This book presents a methodology for the real-time scheduling problems of real-time systems (RTS) from the viewpoint of control theory. Generally, any system can be viewed as an RTS if it performs real-time application functions and behaves correctly depending on given logical activities and satisfying specified deadlines for the activities. This monograph provides broad views and detailed introductions to supervisory control theory (SCT) and its application in real-time scheduling and reconfiguration. Based on three popular SCT modelling frameworks, discrete-event system (DES), timed DES (TDES), and state-tree structures (STS), the authors provide RTS modelling frameworks; thereafter, SCT is used to find their safe execution sequences.As the main contribution, we use (untimed) DES events to represent the execution and preemption of each individual RTS task. This modelling formalism brings the possibilities to model the preemptions of tasks¿ executions. Furthermore, in some cases, priorities cannot be assigned to real-time tasks. In order to solve this problem, a matrix-based priority-free conditional-preemption (PFCP) relation is provided, which generalizes fixed-priority (FP) RTS scheduling. As a natural extension, a generalized modular modelling framework is presented to model the task parameters instead of the global real-time task. The modular models are taken to be generic entities, which also considers the exact execution time of real-time tasks. STS are undoubtedly recognized as a computationally efficient SCT framework which manages the state explosion problem significantly. Hence, building on the (untimed) modular RTS models, a novel STS-based RTS modeling framework is formulated, by assigning dynamic priorities as specified optimality criteria, which can be utilized to model sporadic RTS processing both sporadic and (multi-period) periodic tasks, providing a small set of the safe execution sequences which rank at the top.

Artificial intelligence (AI) is the study and development of computer systems capable of performing activities normally requiring human intelligence. Among these are such activities as linguistic comprehension, pattern recognition, problem solving, and experiential learning. Scientists, academics, and the general public alike have become fascinated by the idea of AI, which has led to tremendous technological advances. From its origins in ancient mythology to its applications in cutting-edge AI research today, this essay presents a comprehensive review of the field. Myths and Theories from the PastAncient cultures and mythologies frequently feature artificial entities with human-level intellect. Hephaestus, the Greek deity of blacksmiths and craftspeople, was able to accomplish much more with the help of his mechanical workers. Similar accounts of automata and artificial birds that may pass for human are found in ancient Chinese and Egyptian writings. These early ideas paved the way for the modern interest with building artificially intelligent devices. When Artificial Intelligence Began: Alan Turing and the Turing TestThe seminal work of British mathematician and logician Alan Turing in the middle of the 20th century marked the beginning of the contemporary era of artificial intelligence. To assess whether or not a machine is capable of intelligent behavior that is indistinguishable from that of a person, Turing developed a test in 1950. The Turing Test is an important notion in the history of artificial intelligence. Interest in creating machines that could mimic human mind was aroused by Turing's ideas. Expert Systems and the Coming "AI Winter"Expert systems were made possible by breakthroughs in artificial intelligence research in the 1960s and 1970s. These programs have the ability to tackle difficult problems and offer insightful analysis since they were developed to emulate human competence in specific subjects. However, the initial euphoria surrounding AI dissipated in the 1980s due to false expectations, technical constraints, and a lack of financing. The AI winter was a temporary lull in the progress of AI studies. The Explosion of Neural Networks and Machine LearningImprovements in machine learning and neural networks sparked a revival of interest in AI in the latter part of the 20th century. To enable computers to learn from data, recognize patterns, and make predictions without explicit programming, machine learning algorithms were developed. Inspired by the structure of the human brain, neural networks became an essential part in creating advanced AI systems that can do tasks such as image identification and natural language processing.

This book provides a coherent and complete overview of various Question Answering (QA) systems. It covers three main categories based on the source of the data that can be unstructured text (TextQA), structured knowledge graphs (KBQA), and the combination of both. Developing a QA system usually requires using a combination of various important techniques, including natural language processing, information retrieval and extraction, knowledge graph processing, and machine learning.After a general introduction and an overview of the book in Chapter 1, the history of QA systems and the architecture of different QA approaches are explained in Chapter 2. It starts with early close domain QA systems and reviews different generations of QA up to state-of-the-art hybrid models. Next, Chapter 3 is devoted to explaining the datasets and the metrics used for evaluating TextQA and KBQA. Chapter 4 introduces the neural and deep learning models used in QA systems. This chapter includes the required knowledge of deep learning and neural text representation models for comprehending the QA models over text and QA models over knowledge base explained in Chapters 5 and 6, respectively. In some of the KBQA models the textual data is also used as another source besides the knowledge base; these hybrid models are studied in Chapter 7. In Chapter 8, a detailed explanation of some well-known real applications of the QA systems is provided. Eventually, open issues and future work on QA are discussed in Chapter 9.This book delivers a comprehensive overview on QA over text, QA over knowledge base, and hybrid QA systems which can be used by researchers starting in this field. It will help its readers to follow the state-of-the-art research in the area by providing essential and basic knowledge.

This book, fully updated for Python version 3.6+, covers the key ideas that link probability, statistics, and machine learning illustrated using Python modules in these areas.  All the figures and numerical results are reproducible using the Python codes provided. The author develops key intuitions in machine learning by working meaningful examples using multiple analytical methods and Python codes, thereby connecting theoretical concepts to concrete implementations. Detailed proofs for certain important results are also provided. Modern Python modules like Pandas, Sympy, Scikit-learn, Tensorflow, and Keras are applied to simulate and visualize important machine learning concepts like the bias/variance trade-off, cross-validation, and regularization. Many abstract mathematical ideas, such as convergence in probability theory, are developed and illustrated with numerical examples. This updated edition now includes the Fisher Exact Test and the Mann-Whitney-Wilcoxon Test. A new section on survival analysis has been included as well as substantial development of Generalized Linear Models. The new deep learning section for image processing includes an in-depth discussion of gradient descent methods that underpin all deep learning algorithms.   As with the prior edition, there are new and updated *Programming Tips* that the illustrate effective Python modules and methods for scientific programming and machine learning. There are 445 run-able code blocks with corresponding outputs that have been tested for accuracy.  Over 158 graphical visualizations (almost all generated using Python) illustrate the concepts that are developed both in code and in mathematics. We also discuss and use key Python modules such as Numpy, Scikit-learn, Sympy,  Scipy, Lifelines, CvxPy, Theano, Matplotlib, Pandas, Tensorflow, Statsmodels,  and Keras.This book is suitable for anyone with an undergraduate-level exposure to probability, statistics, or machine learning and with rudimentary knowledge of Python programming.
