The Design and Verification of Dynamic-sized Nonblocking Data Structures

<p>Modern computer systems often involve multiple processes or threads of control that communicate through shared memory. However, the implementation of correct and efficient data structures that can be shared by several processes is frequently challenging. This thesis is concerned with the design and verification of a class of shared memory algorithms known as nonblocking algorithms, which are implementations of shared data structures that provide strong progress guarantees. Nonblocking algorithms offer an appealing alternative to traditional techniques for the implementation of shared memory data structures, but they are difficult to design, and extant algorithms can often be applied in only a limited range of systems. Furthermore, because of their subtlety, it is notoriously difficult to determine whether a given nonblocking algorithm is correct. This thesis addresses these difficulties in two ways. First, we present techniques for the verification of nonblocking algorithms that dynamically allocate memory. These techniques allow the construction of formal and complete proofs of correctness, so that each proof may be checked by a mechanical proof assistant. Applying techniques first developed for the verification of distributed algorithms, we use labelled-transition systems to model algorithms and their specifications, and simulation relations to prove that an implementation meets its specification. Nonblocking algorithms often require a particular notion of simulation, called backward simulation, that is rarely necessary in other contexts. This thesis contributes to the relatively limited collective experience in the use of backward simulation. The second set of contributions addresses the limitations of many extant nonblocking algorithms. While many nonblocking algorithms allocate memory dynamically, it is difficult to determine in a nonblocking context when it is safe to free memory. We present techniques to accomplish this. Furthermore, many nonblocking algorithms depend on the availability of two powerful synchronisation primitives, known as load-linked and store-conditional, which are not normally provided by hardware. We present implementations of these primitives that work on commonly available platforms.</p>

Orthogonal Range Search Data Structures

AbstractWe first review existing space-efficient data structures for the orthogonal range search problem. Then, we propose two improved data structures, the first of which has better query time complexity than the existing structures and the second of which has better space complexity that matches the information-theoretic lower bound.

Efficient Data Structures

Efficient data structures for data-driven mechanics, sat solving with gpu accelerated inprocessing.

AbstractSince 2013, the leading SAT solvers in the SAT competition all use inprocessing, which unlike preprocessing, interleaves search with simplifications. However, applying inprocessing frequently can still be a bottle neck, i.e., for hard or large formulas. In this work, we introduce the first attempt to parallelize inprocessing on GPU architectures. As memory is a scarce resource in GPUs, we present new space-efficient data structures and devise a data-parallel garbage collector. It runs in parallel on the GPU to reduce memory consumption and improves memory access locality. Our new parallel variable elimination algorithm is twice as fast as previous work. In experiments our new solver ParaFROST solves many benchmarks faster on the GPU than its sequential counterparts.

I/O-efficient data structures for non-overlapping indexing

Efficient data structures for range shortest unique substring queries.

Let T[1,n] be a string of length n and T[i,j] be the substring of T starting at position i and ending at position j. A substring T[i,j] of T is a repeat if it occurs more than once in T; otherwise, it is a unique substring of T. Repeats and unique substrings are of great interest in computational biology and information retrieval. Given string T as input, the Shortest Unique Substring problem is to find a shortest substring of T that does not occur elsewhere in T. In this paper, we introduce the range variant of this problem, which we call the Range Shortest Unique Substring problem. The task is to construct a data structure over T answering the following type of online queries efficiently. Given a range [α,β], return a shortest substring T[i,j] of T with exactly one occurrence in [α,β]. We present an O(nlogn)-word data structure with O(logwn) query time, where w=Ω(logn) is the word size. Our construction is based on a non-trivial reduction allowing for us to apply a recently introduced optimal geometric data structure [Chan et al., ICALP 2018]. Additionally, we present an O(n)-word data structure with O(nlogϵn) query time, where ϵ>0 is an arbitrarily small constant. The latter data structure relies heavily on another geometric data structure [Nekrich and Navarro, SWAT 2012].

Dynamic and Internal Longest Common Substring

Abstract Given two strings S and T, each of length at most n, the longest common substring (LCS) problem is to find a longest substring common to S and T. This is a classical problem in computer science with an $$\mathcal {O}(n)$$ O ( n ) -time solution. In the fully dynamic setting, edit operations are allowed in either of the two strings, and the problem is to find an LCS after each edit. We present the first solution to the fully dynamic LCS problem requiring sublinear time in n per edit operation. In particular, we show how to find an LCS after each edit operation in $$\tilde{\mathcal {O}}(n^{2/3})$$ O ~ ( n 2 / 3 ) time, after $$\tilde{\mathcal {O}}(n)$$ O ~ ( n ) -time and space preprocessing. This line of research has been recently initiated in a somewhat restricted dynamic variant by Amir et al. [SPIRE 2017]. More specifically, the authors presented an $$\tilde{\mathcal {O}}(n)$$ O ~ ( n ) -sized data structure that returns an LCS of the two strings after a single edit operation (that is reverted afterwards) in $$\tilde{\mathcal {O}}(1)$$ O ~ ( 1 ) time. At CPM 2018, three papers (Abedin et al., Funakoshi et al., and Urabe et al.) studied analogously restricted dynamic variants of problems on strings; specifically, computing the longest palindrome and the Lyndon factorization of a string after a single edit operation. We develop dynamic sublinear-time algorithms for both of these problems as well. We also consider internal LCS queries, that is, queries in which we are to return an LCS of a pair of substrings of S and T. We show that answering such queries is hard in general and propose efficient data structures for several restricted cases.

FSMI: Fast computation of Shannon mutual information for information-theoretic mapping

Exploration tasks are embedded in many robotics applications, such as search and rescue and space exploration. Information-based exploration algorithms aim to find the most informative trajectories by maximizing an information-theoretic metric, such as the mutual information between the map and potential future measurements. Unfortunately, most existing information-based exploration algorithms are plagued by the computational difficulty of evaluating the Shannon mutual information metric. In this article, we consider the fundamental problem of evaluating Shannon mutual information between the map and a range measurement. First, we consider 2D environments. We propose a novel algorithm, called the fast Shannon mutual information (FSMI). The key insight behind the algorithm is that a certain integral can be computed analytically, leading to substantial computational savings. Second, we consider 3D environments, represented by efficient data structures, e.g., an OctoMap, such that the measurements are compressed by run-length encoding (RLE). We propose a novel algorithm, called FSMI-RLE, that efficiently evaluates the Shannon mutual information when the measurements are compressed using RLE. For both the FSMI and the FSMI-RLE, we also propose variants that make different assumptions on the sensor noise distribution for the purpose of further computational savings. We evaluate the proposed algorithms in extensive experiments. In particular, we show that the proposed algorithms outperform existing algorithms that compute Shannon mutual information as well as other algorithms that compute the Cauchy–Schwarz quadratic mutual information (CSQMI). In addition, we demonstrate the computation of Shannon mutual information on a 3D map for the first time.

37 Research Topics In Data Science To Stay On Top Of

• February 22, 2024

As a data scientist, staying on top of the latest research in your field is essential.

The data science landscape changes rapidly, and new techniques and tools are constantly being developed.

To keep up with the competition, you need to be aware of the latest trends and topics in data science research.

In this article, we will provide an overview of 37 hot research topics in data science.

We will discuss each topic in detail, including its significance and potential applications.

These topics could be an idea for a thesis or simply topics you can research independently.

Stay tuned – this is one blog post you don’t want to miss!

37 Research Topics in Data Science

1.) predictive modeling.

Predictive modeling is a significant portion of data science and a topic you must be aware of.

Simply put, it is the process of using historical data to build models that can predict future outcomes.

Predictive modeling has many applications, from marketing and sales to financial forecasting and risk management.

As businesses increasingly rely on data to make decisions, predictive modeling is becoming more and more important.

While it can be complex, predictive modeling is a powerful tool that gives businesses a competitive advantage.

2.) Big Data Analytics

These days, it seems like everyone is talking about big data.

And with good reason – organizations of all sizes are sitting on mountains of data, and they’re increasingly turning to data scientists to help them make sense of it all.

But what exactly is big data? And what does it mean for data science?

Simply put, big data is a term used to describe datasets that are too large and complex for traditional data processing techniques.

Big data typically refers to datasets of a few terabytes or more.

But size isn’t the only defining characteristic – big data is also characterized by its high Velocity (the speed at which data is generated), Variety (the different types of data), and Volume (the amount of the information).

Given the enormity of big data, it’s not surprising that organizations are struggling to make sense of it all.

That’s where data science comes in.

Data scientists use various methods to wrangle big data, including distributed computing and other decentralized technologies.

With the help of data science, organizations are beginning to unlock the hidden value in their big data.

By harnessing the power of big data analytics, they can improve their decision-making, better understand their customers, and develop new products and services.

3.) Auto Machine Learning

Auto machine learning is a research topic in data science concerned with developing algorithms that can automatically learn from data without intervention.

This area of research is vital because it allows data scientists to automate the process of writing code for every dataset.

This allows us to focus on other tasks, such as model selection and validation.

Auto machine learning algorithms can learn from data in a hands-off way for the data scientist – while still providing incredible insights.

This makes them a valuable tool for data scientists who either don’t have the skills to do their own analysis or are struggling.

4.) Text Mining

Text mining is a research topic in data science that deals with text data extraction.

This area of research is important because it allows us to get as much information as possible from the vast amount of text data available today.

Text mining techniques can extract information from text data, such as keywords, sentiments, and relationships.

This information can be used for various purposes, such as model building and predictive analytics.

5.) Natural Language Processing

Natural language processing is a data science research topic that analyzes human language data.

This area of research is important because it allows us to understand and make sense of the vast amount of text data available today.

Natural language processing techniques can build predictive and interactive models from any language data.

Natural Language processing is pretty broad, and recent advances like GPT-3 have pushed this topic to the forefront.

6.) Recommender Systems

Recommender systems are an exciting topic in data science because they allow us to make better products, services, and content recommendations.

Businesses can better understand their customers and their needs by using recommender systems.

This, in turn, allows them to develop better products and services that meet the needs of their customers.

Recommender systems are also used to recommend content to users.

This can be done on an individual level or at a group level.

Think about Netflix, for example, always knowing what you want to watch!

Recommender systems are a valuable tool for businesses and users alike.

7.) Deep Learning

Deep learning is a research topic in data science that deals with artificial neural networks.

These networks are composed of multiple layers, and each layer is formed from various nodes.

Deep learning networks can learn from data similarly to how humans learn, irrespective of the data distribution.

This makes them a valuable tool for data scientists looking to build models that can learn from data independently.

The deep learning network has become very popular in recent years because of its ability to achieve state-of-the-art results on various tasks.

There seems to be a new SOTA deep learning algorithm research paper on  https://arxiv.org/  every single day!

8.) Reinforcement Learning

Reinforcement learning is a research topic in data science that deals with algorithms that can learn on multiple levels from interactions with their environment.

This area of research is essential because it allows us to develop algorithms that can learn non-greedy approaches to decision-making, allowing businesses and companies to win in the long term compared to the short.

9.) Data Visualization

Data visualization is an excellent research topic in data science because it allows us to see our data in a way that is easy to understand.

Data visualization techniques can be used to create charts, graphs, and other visual representations of data.

This allows us to see the patterns and trends hidden in our data.

Data visualization is also used to communicate results to others.

This allows us to share our findings with others in a way that is easy to understand.

There are many ways to contribute to and learn about data visualization.

Some ways include attending conferences, reading papers, and contributing to open-source projects.

10.) Predictive Maintenance

Predictive maintenance is a hot topic in data science because it allows us to prevent failures before they happen.

This is done using data analytics to predict when a failure will occur.

This allows us to take corrective action before the failure actually happens.

• Contribution to knowledge: Research papers contribute to the body of knowledge in a particular field or discipline. They add new information, insights, and perspectives to existing literature and help advance the understanding of a particular phenomenon or issue.
• Opportunity for intellectual growth: Research papers provide an opportunity for intellectual growth for the researcher. They require critical thinking, problem-solving, and creativity, which can help develop the researcher’s skills and knowledge.
• Career advancement: Research papers can help advance the researcher’s career by demonstrating their expertise and contributions to the field. They can also lead to new research opportunities, collaborations, and funding.
• Academic recognition: Research papers can lead to academic recognition in the form of awards, grants, or invitations to speak at conferences or events. They can also contribute to the researcher’s reputation and standing in the field.
• Impact on policy and practice: Research papers can have a significant impact on policy and practice. They can inform policy decisions, guide practice, and lead to changes in laws, regulations, or procedures.
• Advancement of society: Research papers can contribute to the advancement of society by addressing important issues, identifying solutions to problems, and promoting social justice and equality.

Limitations of Research Paper

Research papers also have some limitations that should be considered when interpreting their findings or implications. Here are some common limitations of research papers:

• Limited generalizability: Research findings may not be generalizable to other populations, settings, or contexts. Studies often use specific samples or conditions that may not reflect the broader population or real-world situations.
• Potential for bias : Research papers may be biased due to factors such as sample selection, measurement errors, or researcher biases. It is important to evaluate the quality of the research design and methods used to ensure that the findings are valid and reliable.
• Ethical concerns: Research papers may raise ethical concerns, such as the use of vulnerable populations or invasive procedures. Researchers must adhere to ethical guidelines and obtain informed consent from participants to ensure that the research is conducted in a responsible and respectful manner.
• Limitations of methodology: Research papers may be limited by the methodology used to collect and analyze data. For example, certain research methods may not capture the complexity or nuance of a particular phenomenon, or may not be appropriate for certain research questions.
• Publication bias: Research papers may be subject to publication bias, where positive or significant findings are more likely to be published than negative or non-significant findings. This can skew the overall findings of a particular area of research.
• Time and resource constraints: Research papers may be limited by time and resource constraints, which can affect the quality and scope of the research. Researchers may not have access to certain data or resources, or may be unable to conduct long-term studies due to practical limitations.

Damages to various building structures often occur over their service life and can occasionally lead to severe structural failures, threatening the lives of its residents. In recent years, special attention has been paid to investigating various damages in buildings at the early stage to avoid failures and thereby minimize maintenance. Structural health monitoring can be used as a tool for damage quantification using vibration measurements. The application of various sensors for measuring accelerations, velocity and displacement in civil infrastructure monitoring has a long history in vibration-based approaches. These types of sensors reveal dynamic characteristics which are global in nature and ineffective in case of minor damage identification. In a practical application, the available damage detection approaches are not fully capable of quickly sensing and accurately identifying the realistic damage in structures. Research on damage identification from strain data is an interesting topic in recent days. Some work on the cross-correlation approach is now a centre of attraction and strictly confined to bridge or symmetric structures. The present paper uses strain data to validate the cross-correlation approach for detecting damage to building structures. The effectiveness of the methodology has been illustrated firstly on a simply supported beam, then on a 5-storey steel frame and a 6-storey scaled-down reinforced concrete shear building and lastly on a frame structure with moving load as a special case. The results show that this approach has the potential to identify damages in different kinds of civil infrastructure.

What public k-12 teachers want americans to know about teaching.

Illustrations by Hokyoung Kim

At a time when most teachers are feeling stressed and overwhelmed in their jobs, we asked 2,531 public K-12 teachers this open-ended question:

If there’s one thing you’d want the public to know about teachers, what would it be?

We also asked Americans what they think about teachers to compare with teachers’ perceptions of how the public views them.

Related: What’s It Like To Be a Teacher in America Today?

Pew Research Center conducted this analysis to better understand what public K-12 teachers would like Americans to know about their profession. We also wanted to learn how the public thinks about teachers.

For the open-end question, we surveyed 2,531 U.S. public K-12 teachers from Oct. 17 to Nov. 14, 2023. The teachers surveyed are members of RAND’s American Teacher Panel, a nationally representative panel of public K-12 school teachers recruited through MDR Education. Survey data is weighted to state and national teacher characteristics to account for differences in sampling and response to ensure they are representative of the target population.

Overall, 96% of surveyed teachers provided an answer to the open-ended question. Center researchers developed a coding scheme categorizing the responses, coded all responses, and then grouped them into the six themes explored in the data essay.

For the questions for the general public, we surveyed 5,029 U.S. adults from Nov. 9 to Nov. 16, 2023. The adults surveyed are members of the Ipsos KnowledgePanel, a nationally representative online survey panel. Panel members are randomly recruited through probability-based sampling, and households are provided with access to the Internet and hardware if needed. To ensure that the results of this survey reflect a balanced cross section of the nation, the data is weighted to match the U.S. adult population by gender, age, education, race and ethnicity and other categories.

Here are the questions used for this analysis , along with responses, the teacher survey methodology and the general public survey methodology .

Most of the responses to the open-ended question fell into one of these six themes:

Teaching is a hard job

About half of teachers (51%) said they want the public to know that teaching is a difficult job and that teachers are hardworking. Within this share, many mentioned that they have roles and responsibilities in the classroom besides teaching, which makes the job stressful. Many also talked about working long hours, beyond those they’re contracted for.

“Teachers serve multiple roles other than being responsible for teaching curriculum. We are counselors, behavioral specialists and parents for students who need us to fill those roles. We sacrifice a lot to give all of ourselves to the role as teacher.”

– Elementary school teacher

“The amount of extra hours that teachers have to put in beyond the contractual time is ridiculous. Arriving 30 minutes before and leaving an hour after is just the tip of the iceberg. … And as far as ‘having summers off,’ most of August is taken up with preparing materials for the upcoming school year or attending three, four, seven days’ worth of unpaid development training.”

– High school teacher

Teachers care about their students

The next most common theme: 22% of teachers brought up how fulfilling teaching is and how much teachers care about their students. Many gave examples of the hardships of teaching but reaffirmed that they do their job because they love the kids and helping them succeed. 

“We are passionate about what we do. Every child we teach is important to us and we look out for them like they are our own.”

– Middle school teacher

“We are in it for the kids, and the most incredible moments are when children make connections with learning.”

Teachers are undervalued and disrespected

Some 17% of teachers want the public to know that they feel undervalued and disrespected, and that they need more public support. Some mentioned that they are well-educated professionals but are not treated as such. And many teachers in this category responded with a general plea for support from the public, which they don’t feel they’re getting now.

“We feel undervalued. The public and many parents of my students treat me and my peers as if we do not know as much as they do, as if we are uneducated.”

“The public attitudes toward teachers have been degrading, and it is making it impossible for well-qualified teachers to be found. People are simply not wanting to go into the profession because of public sentiments.”

Teachers are underpaid

A similar share of teachers (15%) want the public to know that teachers are underpaid. Many teachers said their salary doesn’t account for the effort and care they put into their students’ education and believe that their pay should reflect this.

“We are sorely underpaid for the amount of hours we work and the education level we have attained.”

Teachers need support and resources from government and administrators

About one-in-ten teachers (9%) said they need more support from the government, their administrators and other key stakeholders. Many mentioned working in understaffed schools, not having enough funding and paying for supplies out of pocket. Some teachers also expressed that they have little control over the curriculum that they teach.

“The world-class education we used to be proud of does not exist because of all the red tape we are constantly navigating. If you want to see real change in the classroom, advocate for smaller class sizes for your child, push your district to cap class sizes at a reasonable level and have real, authentic conversations with your child’s teacher about what is going on in the classroom if you’re curious.”

Teachers need more support from parents

Roughly the same share of teachers (8%) want the public to know that teachers need more support from parents, emphasizing that the parent-teacher relationship is strained. Many view parents as partners in their child’s education and believe that a strong relationship improves kids’ overall social and emotional development.

“Teachers help students to reach their potential. However, that job is near impossible if parents/guardians do not take an active part in their student’s education.”

How the U.S. public views teachers

While the top response from teachers in the open-ended question is that they want the public to know that teaching is a hard job, most Americans already see it that way. Two-thirds of U.S. adults say being a public K-12 teacher is harder than most other jobs, with 33% saying it’s a lot harder.

And about three-quarters of Americans (74%) say teachers should be paid more than they are now, including 39% who say teachers should be paid a lot more.

Americans are about evenly divided on whether the public generally looks up to (32%) or down on (30%) public K-12 teachers. Some 37% say Americans neither look up to or down on public K-12 teachers.

In addition to the open-ended question about what they want the public to know about them, we asked teachers how much they think most Americans trust public K-12 teachers to do their job well. We also asked the public how much they trust teachers. Answers differ considerably.

Nearly half of public K-12 teachers (47%) say most Americans don’t trust teachers much or at all. A third say most Americans trust teachers some, and 18% say the public trusts teachers a great deal or a fair amount.

In contrast, a majority of Americans (57%) say they do trust public K-12 teachers to do their job well a great deal or a fair amount. About a quarter (26%) say they trust teachers some, and 17% say they don’t trust teachers much or at all.

How the public’s views differ by party

There are sizable party differences in Americans’ views of teachers. In particular, Democrats and Democratic-leaning independents are more likely than Republicans and Republican leaners to say:

• They trust teachers to do their job well a great deal or a fair amount (70% vs. 44%)
• Teaching is a lot or somewhat harder when compared with most other jobs (77% vs. 59%)
• Teachers should be paid a lot or somewhat more than they are now (86% vs. 63%)

In their own words

Below, we have a selection of quotes that describe what teachers want the public to know about them and their profession.
