Flach December 2000 CSTR-00-018 On the state of the art in Machine Learning: a personal review Peter A. Flach December 15, 2000 Abstract This paper reviews a number of recent books related to current developments in machine learning. Some (anticipated) trends will be sketched. These include: a trend towards combining approaches that were hitherto regarded as distinct and were studied by separate research communities; a trend towards a more prominent role of representation; and a tighter integration of machine learning techniques with techniques from areas of application such as bioinformatics. The intended readership has some knowledge of what machine learning is about, but brief tuto- rial introductions to some of the more specialist research areas will also be given. 1 Introduction This paper reviews a number of books that appeared recently in my main area of exper- tise, machine learning. Following a request from the book review editors of Artificial Intelligence, I selected about a dozen books with which I either was already familiar, or which I would be happy to read in order to find out what’s new in that particular area of the field. The choice of books is therefore subjective rather than comprehensive (and also biased towards books I liked). However, it does reflect a personal view of what I think are exciting developments in machine learning, and as a secondary aim of this paper I will expand a bit on this personal view, sketching some of the current and anticipated future trends.

    UNIVERSITY OF CALIFORNIA Los Angeles Data-Driven Learning of Invariants and Specifications A dissertation submitted in partial satisfaction of the requirements for the degree Doctor of Philosophy in Computer Science by Saswat Padhi 2020 © Copyright by Saswat Padhi 2020 ABSTRACT OF THE DISSERTATION Data-Driven Learning of Invariants and Specifications by Saswat Padhi Doctor of Philosophy in Computer Science University of California, Los Angeles, 2020 Professor Todd D. Millstein, Chair Although the program verification community has developed several techniques for analyzing software and formally proving their correctness, these techniques are too sophisticated for end users and require significant investment in terms of time and effort. In this dissertation, I present techniques that help programmers easily formalize the initial requirements for verifying their programs — specifications and inductive invariants. The proposed techniques leverage ideas from program synthesis and statistical learning to automatically generate these formal requirements from readily available program-related data, such as test cases, execution traces etc. I detail three of these data-driven learning techniques – FlashProfile and PIE for specification learning, and LoopInvGen for invariant learning. I conclude with some principles for building robust synthesis engines, which I learned while refining the aforementioned techniques. Since program synthesis is a form of function learning, it is perhaps unsurprising that some of the fundamental issues in program synthesis have also been explored in the machine learning community. I study one particular phenomenon — overfitting. I present a formalization of overfitting in program synthesis, and discuss two mitigation strategies, inspired by existing techniques. ii The dissertation of Saswat Padhi is approved.

Keywords: machine learning, natural language processing, computational social science, graphical models, interpretability, calibration, conformal methods Abstract Natural language corpora are phenomenally rich resources for learning about people and society, and have long been used as such by various disciplines such as history and political science. Recent advances in machine learning and natural language pro- cessing are creating remarkable new possibilities for how scholars might analyze such corpora, but working with textual data brings its own unique challenges, and much of the research in computer science may not align with the desiderata of social scien- tists. In this thesis, I present a line of work on developing methods for computational social science focused primarily on observational research using natural language text. Throughout, I take seriously the concerns and priorities of the social sciences, leading to a focus on aspects of machine learning which are otherwise sometimes secondary, including calibration, interpretability, and transparency. Two ideas which unify this work are the problems of exploration and measurement, and as a running example I consider the problem of analyzing how news sources frame contemporary political issues.

  • Teaching with IMPACT
    Teaching with IMPACT Carl Trimbach [email protected] Michael Littman [email protected] Abstract Like many problems in AI in their general form, supervised learning is computationally intractable. We hypothesize that an important reason humans can learn highly complex and varied concepts, in spite of the computational difficulty, is that they benefit tremendously from experienced and insightful teachers. This paper proposes a new learning framework that provides a role for a knowledgeable, benevolent teacher to guide the process of learning a target concept in a series of \curricular" phases or rounds. In each round, the teacher's role is to act as a moderator, exposing the learner to a subset of the available training data to move it closer to mastering the target concept. Via both theoretical and empirical evidence, we argue that this framework enables simple, efficient learners to acquire very complex concepts from examples. In particular, we provide multiple examples of concept classes that are known to be unlearnable in the standard PAC setting along with provably efficient algorithms for learning them in our extended setting. A key focus of our work is the ability to learn complex concepts on top of simpler, previously learned, concepts|a direction with the potential of creating more competent artificial agents. 1. Introduction In statistical learning theory, the PAC (probably approximately correct) model (Valiant, 1984) has been a valuable tool for framing and understanding the problem of learning from examples. Many interesting and challenging problems can be analyzed and attacked in the PAC setting, resulting in powerful algorithms. Nevertheless, there exist many central and relevant concept classes that are provably unlearnable this way.

  • On-Device Machine Learning: an Algorithms and Learning Theory Perspective
    On-Device Machine Learning: An Algorithms and Learning Theory Perspective SAUPTIK DHAR, America Research Center, LG Electronics JUNYAO GUO, America Research Center, LG Electronics JIAYI (JASON) LIU, America Research Center, LG Electronics SAMARTH TRIPATHI, America Research Center, LG Electronics UNMESH KURUP, America Research Center, LG Electronics MOHAK SHAH, America Research Center, LG Electronics The predominant paradigm for using machine learning models on a device is to train a model in the cloud and perform inference using the trained model on the device. However, with increasing number of smart devices and improved hardware, there is interest in performing model training on the device. Given this surge in interest, a comprehensive survey of the field from a device-agnostic perspective sets the stage for both understanding the state-of-the-art and for identifying open challenges and future avenues of research. However, on-device learning is an expansive field with connections to a large number of related topics in AI and machine learning (including online learning, model adaptation, one/few-shot learning, etc.). Hence, covering such a large number of topics in a single survey is impractical. This survey finds a middle ground by reformulating the problem of on-device learning as resource constrained learning where the resources are compute and memory. This reformulation allows tools, techniques, and algorithms from a wide variety of research areas to be compared equitably. In addition to summarizing the state-of-the-art, the survey also identifies a number of challenges and next steps for both the algorithmic and theoretical aspects ofon-device learning.

    A Sub-Linear Time Framework for Geometric Optimization with Outliers in High Dimensions Hu Ding School of Computer Science and Technology, University of Science and Technology of China, Anhui, China http://staff.ustc.edu.cn/~huding/index.html [email protected] Abstract Many real-world problems can be formulated as geometric optimization problems in high dimensions, especially in the fields of machine learning and data mining. Moreover, we often need to take into account of outliers when optimizing the objective functions. However, the presence of outliers could make the problems to be much more challenging than their vanilla versions. In this paper, we study the fundamental minimum enclosing ball (MEB) with outliers problem first; partly inspired by the core-set method from Bădoiu and Clarkson, we propose a sub-linear time bi-criteria approximation algorithm based on two novel techniques, the Uniform-Adaptive Sampling method and Sandwich Lemma. To the best of our knowledge, our result is the first sub-linear time algorithm, which has the sample size (i.e., the number of sampled points) independent of both the number of input points n and dimensionality d, for MEB with outliers in high dimensions. Furthermore, we observe that these two techniques can be generalized to deal with a broader range of geometric optimization problems with outliers in high dimensions, including flat fitting, k-center clustering, and SVM with outliers, and therefore achieve the sub-linear time algorithms for these problems respectively. 2012 ACM Subject Classification Theory of computation → Approximation algorithms analysis Keywords and phrases minimum enclosing ball, outliers, shape fitting, high dimensions, sub-linear time Digital Object Identifier 10.4230/LIPIcs.ESA.2020.38 Related Version A full version of the paper is available at https://arxiv.org/abs/2004.10090.
