Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in deep machine learning hinge on a large amount of labeled data. Such heavy dependence on supervision data impedes the broader application of deep learning in more practical scenarios, where data annotation and labeling can be expensive (e.g. high-frequency trading) or even dangerous (e.g. training autonomous-driving models.) Transfer Learning (TL), equivalently referred to as knowledge transfer, is an effective strategy to confront such challenges. TL, by its definition, distills the external knowledge from relevant domains into the target learning domain, hence requiring fewer supervision resources than learning-from-scratch. TL is beneficial for learning tasks for which the supervision data is limited or even unavailable. It is also an essential property to realize Generalized Artificial Intelligence. In this thesis, we propose sample-efficient TL approaches using limited, sometimes unreliable resources. We take a deep look into the setting of Reinforcement Learning (RL) and Supervised Learning, and derive solutions for the two domains respectively. Especially, for RL, we focus on a problem setting called imitation learning, where the supervision from the environment is either non-available or scarcely provided, and the learning agent must transfer knowledge from exterior resources, such as demonstration examples of a previously trained expert, to learn a good policy. For supervised learning, we consider a distributed machine learning scheme called Federated Learning (FL), which is a more challenging scenario than traditional machine learning, since the training data is distributed and non-sharable during the learning process. Under this distributed setting, it is imperative to enable TL among distributed learning clients to reach a satisfiable generalization performance. We prove by both theoretical support and extensive experiments that our proposed algorithms can facilitate the machine learning process with knowledge transfer to achieve higher asymptotic performance, in a principled and more efficient manner than the prior arts.

Available in PDF, EPUB and Kindle. Book excerpt: Transfer learning deals with how systems can quickly adapt themselves to new situations, tasks and environments. It gives machine learning systems the ability to leverage auxiliary data and models to help solve target problems when there is only a small amount of data available. This makes such systems more reliable and robust, keeping the machine learning model faced with unforeseeable changes from deviating too much from expected performance. At an enterprise level, transfer learning allows knowledge to be reused so experience gained once can be repeatedly applied to the real world. For example, a pre-trained model that takes account of user privacy can be downloaded and adapted at the edge of a computer network. This self-contained, comprehensive reference text describes the standard algorithms and demonstrates how these are used in different transfer learning paradigms. It offers a solid grounding for newcomers as well as new insights for seasoned researchers and developers.

Download or read book Prediction Learning and Games written by Nicolo Cesa-Bianchi and published by Cambridge University Press. This book was released on 2006-03-13 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important text and reference for researchers and students in machine learning, game theory, statistics and information theory offers a comprehensive treatment of the problem of predicting individual sequences. Unlike standard statistical approaches to forecasting, prediction of individual sequences does not impose any probabilistic assumption on the data-generating mechanism. Yet, prediction algorithms can be constructed that work well for all possible sequences, in the sense that their performance is always nearly as good as the best forecasting strategy in a given reference class. The central theme is the model of prediction using expert advice, a general framework within which many related problems can be cast and discussed. Repeated game playing, adaptive data compression, sequential investment in the stock market, sequential pattern analysis, and several other problems are viewed as instances of the experts' framework and analyzed from a common nonstochastic standpoint that often reveals new and intriguing connections.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proliferation of Internet technology in daily life has created numerous data. These data may come from a variety of sources, such as social networks, online businesses, sensors,military surveillance and so on. Generally speaking, these data could be either dynamic or static. Such huge amount of data, along with modern powerful computing capabilities, had pushed forward tremendous amount of applications in AI substantially, including computer vision, natural language processing, cyber-security, and etc. However, most applications still depends heavily on labeled data. The need of massive labeled data hinders the progress of AI research since the labeling process is very laborious and costly, and also goes against how human beings learn - human beings do not require many labeled data by drawing inferences.Transfer learning, as a popular machine learning paradigm recently, leverages knowledge from a source domain to effectively learn predictive models in a target domain which does not have sufficient labeled data. In this dissertation, we propose to investigate transfer learning techniques on an extensive of data-driven applications. First, we unveil a heterogeneous domain adaptation framework on multiple data stream settings, and we apply it to detect cyber attacks within the data stream. Then, we show that multitask learning on multiple domains may actually help with the classification and retrieval tasks on Computer Vision(CV) applications. After the two applications, we shift the research scope to the scenario of offline learning, and test our transfer learning algorithm on sentiment classification task in Natural Language Processing (NLP) domain. We extend the application scenarios even further to the political science domain. We discuss the potential of the modern Graph Neural Networks (GNN) and apply it to the applications of time series forecasting with additional spatial information. Such application includes a number of critical tasks in social science, including but not limited to peace research, transportation analysis, and epidemic spread modeling. We further address modeling challenges observed during the aforementioned applications, such as scalability, model complexity and etc.

Download or read book Metric Learning written by Aurélien Muise and published by Springer Nature. This book was released on 2022-05-31 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Similarity between objects plays an important role in both human cognitive processes and artificial systems for recognition and categorization. How to appropriately measure such similarities for a given task is crucial to the performance of many machine learning, pattern recognition and data mining methods. This book is devoted to metric learning, a set of techniques to automatically learn similarity and distance functions from data that has attracted a lot of interest in machine learning and related fields in the past ten years. In this book, we provide a thorough review of the metric learning literature that covers algorithms, theory and applications for both numerical and structured data. We first introduce relevant definitions and classic metric functions, as well as examples of their use in machine learning and data mining. We then review a wide range of metric learning algorithms, starting with the simple setting of linear distance and similarity learning. We show how one may scale-up these methods to very large amounts of training data. To go beyond the linear case, we discuss methods that learn nonlinear metrics or multiple linear metrics throughout the feature space, and review methods for more complex settings such as multi-task and semi-supervised learning. Although most of the existing work has focused on numerical data, we cover the literature on metric learning for structured data like strings, trees, graphs and time series. In the more technical part of the book, we present some recent statistical frameworks for analyzing the generalization performance in metric learning and derive results for some of the algorithms presented earlier. Finally, we illustrate the relevance of metric learning in real-world problems through a series of successful applications to computer vision, bioinformatics and information retrieval.

Download or read book Transfer Learning and Deep Domain Adaptation written by Jing He and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transfer learning is an emerging technique in machine learning, by which we can solve a new task with the knowledge obtained from an old task in order to address the lack of labeled data. In particular deep domain adaptation (a branch of transfer learning) gets the most attention in recently published articles. The intuition behind this is that deep neural networks usually have a large capacity to learn representation from one dataset and part of the information can be further used for a new task. In this research, we firstly present the complete scenarios of transfer learning according to the domains and tasks. Secondly, we conduct a comprehensive survey related to deep domain adaptation and categorize the recent advances into three types based on implementing approaches: fine-tuning networks, adversarial domain adaptation, and sample-reconstruction approaches. Thirdly, we discuss the details of these methods and introduce some typical real-world applications. Finally, we conclude our work and explore some potential issues to be further addressed.

Book excerpt: Transfer Learning: Algorithms and Applications presents an in-depth discussion on practices for transfer learning, exploring emerging fields that includes a theoretical analysis of various algorithms and problems that lay a solid foundation for future advances in the field. In the era of Big Data, machine learning methods are widely used in natural language processing, computer vision, speech, and in signal processing communities. However, the current standard machine learning techniques, such as supervised classifiers, tend to fail when the data distribution and/or structure changes over training and test settings. Current techniques addressing machine learning problems can only address a few isolated tasks at one time. Transfer learning, adapted from how humans learn, models the distribution and structure difference between training and test settings.

Download or read book A Prototype oriented Framework for Deep Transfer Learning Applications written by Korawat Tanwisuth and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep learning models achieve state-of-the-art performance in many applications but often require large-scale data. Deep transfer learning studies the ability of deep learning models to transfer knowledge from source tasks to related target tasks, enabling data-efficient learning. This dissertation develops novel methodologies that tackle three different transfer learning applications for deep learning models: unsupervised domain adaptation, unsupervised fine-tuning, and source-private clustering. The key idea behind the proposed methods relies on minimizing the distributional discrepancy between the prototypes and target data with the transport framework. For each scenario, we design our algorithms to suit different data and model requirements. In unsupervised domain adaptation, we leverage the source domain data to construct class prototypes and minimize the transport cost between the prototypes and target data. In unsupervised fine-tuning, we apply our framework to prompt-based zero-shot learning to adapt large pre-trained models directly on the target data, bypassing the source data requirement. In source-private clustering, we incorporate a knowledge distillation framework with our prototype-oriented clustering to address the problem of data and model privacy. All three approaches show consistent performance gains over the baselines
