機器學習(Machine Learning，ML)是人工智能的一個分支，它是一門多領域交叉學科，專門研究計算機怎樣模擬或實現人類的學習行為，涉及概率論、統計學、逼近論、凸分析、算法複雜度理論等多門學科。機器學習方法可以根據經驗數據自動完成模型參數學習，而不需要人為設定規則，大幅降低了人工分析的工作量和難度，已成為目前解決人工智能相關問題的主要方式。

What's the point of art?This is the question Henri asks himself when his class is taken on a school trip to the local art gallery. Who wants pictures of old soup cans or melting watches? But when he encounters a painting with the most perfect blue, it creates a beautiful feeling. It's blueberries, oceans, summer skies and butterflies all rolled into one.And then he wanders into a room with a chair and a sign that reads "Is this really a chair?" Henri decides to test it out, unleashing an explosion of creativity! Finally Henri understands what art is all about... Following Isabelle Marinov's successful Leo and the Octopus, this is a fun and encouraging story of a boy learning to appreciate art and its boundless creativity.

Finance students and practitioners may ask: can machines learn everything? Could AI help me? Computing students or practitioners may ask: which of my skills could contribute to finance? Where in finance should I pay attention? This book aims to answer these questions. No prior knowledge is expected in AI or finance.Including original research, the book explains the impact of ignoring computation in classical economics; examines the relationship between computing and finance and points out potential misunderstandings between economists and computer scientists; and introduces Directional Change and explains how this can be used.To finance students and practitioners, this book will explain the promise of AI, as well as its limitations. It will cover knowledge representation, modelling, simulation and machine learning, explaining the principles of how they work. To computing students and practitioners, this book will introduce the financial applications in which AI has made an impact. This

Cybersecurity attacks grow more complex every day. The first edition of Wilson's COMPTIA PENTEST+ GUIDE TO PENETRATION TESTING helps you gain the knowledge and skills necessary to analyze systems in the same way hackers do. It provides the information you need to successfully pass the CompTIA PenTest+ PTO-002 certification exam and contains detailed examples, projects, and hands-on activities (including virtual machine labs and interactive online features) where you can practice using the actual tools and methodologies needed to be a successful penetration tester. The author begins by exploring the concept of penetration testing, and then walks you through the process of building your own penetration testing lab of virtual machines (hosted on your own computer, which is used to practice the use of pen testing tools and methods). A final project guides you in the creation of a penetration testing report that includes all the areas covered in earlier modules.

An empirical study and analysis of heart disease prediction involves using data analysis techniques to identify patterns and risk factors associated with cardiovascular disease. This approach utilizes machine learning algorithms to classify patients based on their likelihood of developing heart disease.The study involves collecting data on risk factors such as age, gender, family history, blood pressure, cholesterol levels, smoking, and diabetes. Feature selection techniques are used to identify the most important risk factors, and a classification model is trained using these factors. The accuracy of the model is evaluated using metrics such as sensitivity, specificity, and AUC.This empirical study and analysis has several advantages, including the ability to identify new risk factors associated with heart disease, improved accuracy in predicting cardiovascular risk, and the potential to develop more personalized prevention and treatment strategies. This approach has the potential to
