Transition from the traditional Rails MVC trio to an abstraction model and evolve your application codebase with synchronized components, boosting flexibility and maintainabilityKey Features:- Understand Rails' architectural patterns along with its advantages and disadvantages- Organize business logic in Rails apps when the default approach is insufficient- Introduce new abstractions to address design problems- Purchase of the print or Kindle book includes a free PDF eBookBook Description:The Ruby on Rails framework boosts productivity by leveraging the convention-over-configuration principle and model-view-controller (MVC) pattern, enabling developers to build features efficiently. This initial simplicity often leads to complexity, making a well-structured codebase difficult to maintain. Written by a seasoned software engineer and award-winning contributor to many other open-source projects, including Ruby on Rails and Ruby, this book will help you keep your code maintainable while working on a Rails app.You'll get to grips with the framework's capabilities and principles to harness the full potential of Rails, and tackle many common design problems by discovering useful patterns and abstraction layers.

Intelligent patterns frequent from large databases refers to the process of discovering meaningful and significant patterns or associations that occur frequently within vast datasets using intelligent data mining techniques.In data mining and pattern recognition, the term "frequent patterns" usually refers to items, sequences, or subsets that appear frequently in a given dataset. These patterns can provide valuable insights into the underlying relationships, trends, and behaviors within the data.Intelligent Patterns: These are meaningful and relevant patterns that are discovered using advanced algorithms and intelligent data analysis techniques. The intelligence here refers to the ability of the algorithms to identify patterns of interest and discard irrelevant or noise patterns.Frequent Patterns: These are patterns that occur frequently or have high support within the dataset. Support refers to the proportion of transactions or instances in which a particular pattern appears.Large Databases: Refers to datasets that are extensive and contain a significant amount of information. Large databases pose challenges for traditional data analysis methods, making intelligent data mining techniques crucial for effective pattern discovery.The process of finding intelligent frequent patterns from large databases typically involves using algorithms like Apriori, FP-Growth, or Eclat, which efficiently search for itemsets or sequences that meet predefined support and confidence thresholds.Applications of discovering frequent patterns include market basket analysis in retail (finding commonly purchased items together), web usage mining (finding frequently visited web pages), bioinformatics (finding frequent gene associations), and more. These patterns are valuable in decision-making, business intelligence, and predictive analytics, as they can reveal hidden relationships and trends within the data that might not be apparent through simple data examination.

Data structures are the means by which software programs store and retrieve data. This monograph focuses on key-value data structures, which are widely used for data-intensive applications thanks to the versatility of the key-value data model. Key-value data structures constitute the core of any data-driven system. They provide the means to store, search, and modify data residing at various levels of the storage and memory hierarchy. Designing efficient data structures for given workloads has long been a focus of research and practice in both academia and industry. Data Structures for Data-Intensive Applications explains the space of data structure design choices, how to select the appropriate data structure depending on the goals and workload of an application at hand, and how the ever-evolving hardware and data properties require innovations in data structure design. The overarching goal is to help the reader both select the best existing data structures and design and build new ones.

Perspectives of Neurodiverse Participants in Interactive Information Retrieval offers a survey of work to date to inform how interactions in information retrieval systems could afford inclusion of users who are neurodiverse. The existing work is positioned within a range of philosophies, frameworks, and epistemologies that frame the importance of including neurodiverse users in all stages of research and development of Interactive Information Retrieval (IIR) systems. The authors motivate the need for inclusive IIR to develop more broadly, and detail why assistive technologies are not sufficient to ensure inclusive access to information. This survey is motivated by the authors' desire to help transform IIR so that neurodiverse users can both inspire future research and benefit from innovation. This work is presented to students, researchers and practitioners in IIR with a view to provide both knowledge and inspiration towards more inclusive IIR approaches and systems. To that end, the survey contains an overview of each of the chapters to guide the reader to parts of the survey that may be most relevant to the work they are undertaking. The authors also offer examples and practical approaches to include neurodiverse users in IIR research, and explore the challenges ahead in the field.

Reinforcement learning agents have demonstrated remarkable achievements in simulated environments. Data efficiency, however, significantly impedes carrying this success over to real environments. The design of data-efficient agents that address this problem calls for a deeper understanding of information acquisition and representation. This tutorial offers a framework that can guide associated agent design decisions. This framework is inspired in part by concepts from information theory that has grappled with data efficiency for many years in the design of communication systems. In this tutorial, the authors shed light on questions of what information to seek, how to seek that information, and what information to retain. To illustrate the concepts, they design simple agents that build on them and present computational results that highlight data efficiency. This book will be of interest to students and researchers working in reinforcement learning and information theorists wishing to apply their knowledge in a practical way to reinforcement learning problems.
