This pioneering book addresses the question: Are the standard procedures of canonical quantization fully satisfactory, or is there more to learn about assigning a proper quantum system to a given classical system? As shown in this book, the answer to this question is: The standard procedures of canonical quantization are not the whole story!This book offers alternative quantization procedures that complete the story of quantization. The initial chapters are designed to present the new procedures in a clear and simple manner for general readers. As is necessary, systems that exhibit acceptable results with conventional quantization lead to the same results when the new procedures are used for them. However, later chapters examine selected models that lead to unacceptable results when quantized conventionally. Fortunately, these same models lead to acceptable results when the new quantization procedures are used.

This text describes novel treatments of quantum problems using enhanced quantization procedures, generally involving extended correspondence rules for the association of a classical and a quantum theory. Beginning with a review of classical mechanics, the book goes on to detail Hilbert space, quantum mechanics, and scalar quantum field theory. Later chapters further develop analytical skills, study a special class of models, and present a discussion of continuous and discontinuous perturbations. The final chapter offers a brief summary, concluding with a conjecture regarding interacting covariant scalar quantum field theories. Throughout, symmetry is used as a tool to help develop solutions for simple and complex problems alike. Challenging exercises and detailed references are included.

Herb Caen, a popular columnist for the San Francisco Chronicle, recently quoted a Voice of America press release as saying that it was reorganizing in order to "eliminate duplication and redundancy. " This quote both states a goal of data compression and illustrates its common need: the removal of duplication (or redundancy) can provide a more efficient representation of data and the quoted phrase is itself a candidate for such surgery. Not only can the number of words in the quote be reduced without losing informa tion, but the statement would actually be enhanced by such compression since it will no longer exemplify the wrong that the policy is supposed to correct. Here compression can streamline the phrase and minimize the em barassment while improving the English style. Compression in general is intended to provide efficient representations of data while preserving the essential information contained in the data. This book is devoted to the theory and practice of signal compression, i. e. , data compression applied to signals such as speech, audio, images, and video signals (excluding other data types such as financial data or general purpose computer data). The emphasis is on the conversion of analog waveforms into efficient digital representations and on the compression of digital information into the fewest possible bits. Both operations should yield the highest possible reconstruction fidelity subject to constraints on the bit rate and implementation complexity.

Coherent states (CS) were originally introduced in 1926 by Schrödinger and rediscovered in the early 1960s in the context of laser physics. Since then, they have evolved into an extremely rich domain that pervades virtually every corner of physics, and have also given rise to a range of research topics in mathematics. The purpose of the 2016 CIRM conference was to bring together leading experts in the field with scientists interested in related topics, to jointly investigate their applications in physics, their various mathematical properties, and their generalizations in many directions. Instead of traditional proceedings, this book presents sixteen longer review-type contributions, which are the outcome of a collaborative effort by many conference participants, subsequently reviewed by independent experts. The book aptly illustrates the diversity of CS aspects, from purely mathematical topics to physical applications, including quantum gravity.

With numerous breakthroughs over the past several years, deep learning (DL) techniques have transformed the world of artificial intelligence (AI). The abilities that were once considered unique and humane, are now characteristics of powerful machines. State-of-the-art performance across various perceptual tasks from computer vision, speech recognition, game playing, and others, have been demonstrated. Now that we know it works, current research is more directed towards exploring: (a) TinyAI: how to make it more efficient (deployable in resource-constrained devices), through developing new optimization algorithms and tooling; (b) AutoAI: how to reduce human effort and speedup the development cycle of AI systems through automation; (c) InterpretableAI: understand why it works, through detailed theoretical studies; (d) AppliedAI: how to combine all these efforts to move from "Narrow AI" (resolving specific task) into "General AI" (human semi-equivalent). This dissertation primarily takes on the exploration of the first and second directions (autoAI & tinyAI). In particular, we make progress towards developing algorithms for more efficient and automated AI systems with particular focus on quantization methods.(i) Discovering optimal quantization bitwidths. Research question: What is the optimal bitwidth per layer for optimal quantization of a deep neural network? Proposal: we developed a systematic approach to automate the process of discovering the optimal bitwidth for each layer of a deep neural network while complying to the constraint of maintaining the accuracy through an end-to-end deep Reinforcement Learning framework (ReLeQ). (ii) Quantization-aware training. Research question: Can we train a DNN in such a way that makes them inherently robust to quantization? Proposal: we developed a novel quantization-friendly regularization technique based on sinusoidal function, called WaveQ. WaveQ exploits the periodicity, differentiability, and the local convexity profile in sinusoidal functions to automatically propel weights towards values that are inherently closer to quantization levels. Moreover, leveraging the fact that sinusoidal period is a continuous valued parameter, we utilized it as an ideal optimization objective and a proxy to minimize the actual quantization bitwidth, which avoids the issues of gradient-based optimization for discrete valued parameters. (iii) Improved and accelerated finetuning methods. Research question: Can we finetune a quantized DNN in an efficient way to better improve its final accuracy? Proposal: we developed a novel finetuning algorithm for quantized DNNs. The proposed approach utilizes knowledge distillation through teacher-student paradigm in a novel setting that exploits the feature extraction capability of DNNs for higher-accuracy quantization. This divide and conquer strategy makes the training of each student section possible in isolation while all these independently trained sections are later stitched together to form the equivalent fully quantized network.
