An Introduction to Statistical Learning
An Introduction to Statistical Learning provides an accessible overview of the field of statistical learning, an essential toolset for making sense of the vast and complex data sets that have emerged in fields ranging from biology to finance, marketing, and astrophysics in the past twenty years. This book presents some of the most important modeling and prediction techniques, along with relevant applications. Topics include linear regression, classification, resampling methods, shrinkage approaches, tree-based methods, support vector machines, clustering, deep learning, survival analysis, multiple testing, and more. Color graphics and real-world examples are used to illustrate the methods presented. This book is targeted at statisticians and non-statisticians alike, who wish to use cutting-edge statistical learning techniques to analyze their data. Four of the authors co-wrote An Introduction to Statistical Learning, With Applications in R(ISLR), which has become a mainstay of undergraduate and graduate classrooms worldwide, as well as an important reference book for data scientists. One of the keys to its success was that each chapter contains a tutorial on implementing the analyses and methods presented in the R scientific computing environment. However, in recent years Python has become a popular language for data science, and there has been increasing demand for a Python-based alternative to ISLR. Hence, this book (ISLP) covers the same materials as ISLR but with labs implemented in Python. These labs will be useful both for Python novices, as well as experienced users.
Games, Decisions, and Markets
This book critically discusses the historical backgrounds and new developments of the theories of games, decisions, and markets, with many possible applications to social and economic problems. Consisting of three connected parts, the book sheds new light on the role of merchants in the market economy under conditions of risk and uncertainty. Part I begins with the question of why and how John von Neumann and Oskar Morgenstern did joint work in game theory, namely, the theoretical study of strategic interactions among several decision makers. The duel between Sherlock Holmes and Professor Moriarty in Conan Doyle's famous detective story is recalled as a great inducement to Neumann and Morgenstern to invent zero-sum, two-person games. More general non-zero-sum games and associated Nash solutions are then discussed in relation to the generation-gap problem between a young couple and an elderly couple. Part II explores a set of very fundamental problems of individual decision making. Thetwo famous axioms of revealed preference ― Samuelson's weak axiom and Houthakker's axiom ― are skillfully connected and empirically reevaluated by the introduction of certain regularity conditions. The revealed preference approach is then extended from the original commodity space to the dual price space. Such dual treatment in microeconomics is further applied to the theory of cost and production, with the decomposition of the total factor price effect into the substitution and scale effects. Part III turns the reader's attention to the interdependence of several markets. The almost forgotten Hicks-Morishima approach is newly revived with graphical illustrations of traded goods. The well-known Jones-Kemp approach to international trade is boldly expanded into the world of risk and uncertainty. Some striking results in comparative static analysis are derived, with favorable implications for the real world.

Changing methodologies for better maths learning
This research aims to analyse the potential of the connection between Mathematical Modelling and constructivism and its contribution as a methodology in pedagogical practices in the classroom in the teaching-learning process in General Secondary Education (1st Cycle) at Matola Secondary School. This study came about as a result of the realisation that the pedagogical practices in place in the majority of schools do not respond to current social demands, as students are limited to receiving the knowledge transmitted by the teacher without criticising it, which compromises the quality of education and their skills. In view of this, the use of mathematical modelling combined with the constructivist approach contributes to an effective teaching practice, making students active, reflective, participative and capable of producing their own knowledge.
Mathematical modelling Use of public transparency
Teaching maths isn't just about asking students to solve complicated problems, it's about giving them the thoughts, methods and logical reasoning, as well as providing them with the ability to deal with the exact science, giving some the opportunity to choose to follow this marvellous universal path. This book, which is innovative in its teaching ideas due to the encouragement of new technologies, recalls the history of maths teaching and enables the reader to understand why it is necessary to move forward with the use of the most up-to-date resources. It shows the step-by-step process of setting up games or working with mathematical modelling and provides examples that will make it easier for the teacher to understand what is proposed and then work not just with small inspectors, but with curious people with unlimited interests. Learners, who have already been synchronised for a long time, will certainly have the intention of continuing the human legacy on planet Earth. The use of Transparency made available by public bodies during the Modelling games brings the lessons into the reality where the future citizen must act wisely and confidently in the proper understanding of Mathematics. It makes the lesson fun and interesting, and helps solve problems.
Low Biological Energies

From questioning to questioning the coordination of cellular activity, marine historian and naturalist Claude ROUQUETTE embarks on a navigation at sight, to plumb the depths of low energies in order to take stock of the complex processes in biological evolution, intimately associated with the transformations of civilization.
Image Analysis for Vision-Based Skimming
Infestation with invasive aquatic weeds is a major problem being faced while maintaining inland water bodies. Cleaning the surface pollution ideally requires a fully autonomous trash skimmer with capabilities for detecting the presence and finding the physical location of nearby free- floating weed clusters, collection of weed clusters using cutting of matted weeds, if required, moving the skimmer close to the cluster, collecting the cluster, and moving the collected weeds to the bank. Vision enabled trash skimmer consists of a trash skimmer connected to a vision sensor with capability to capture individual video frames and analyze them to extract desired information. Under these conditions, providing visual information of the surroundings to the trash skimmer will make its operations more convenient, accurate and improve its overall performance. This book focuses on improving the performance of the image processing steps namely horizon line detection techniques for segmenting water regions, object detection algorithm for segmenting floating objects on the water surface, color based edge detection algorithm to estimate green-colored weeds in inland water bodies.
Incidence of Technology as a Pedagogical Tool
Technologies have revolutionized education, transforming the way we learn and teach, allowing us to explore their impact on the different levels of curricular concretion, at the macro curricular level: the general objectives, the competencies to be developed and the evaluation criteria are established at a global level, by integrating technologies the teaching strategies are enhanced and fostering the acquisition of digital competencies necessary in today's society; at the meso-curricular level, the specific contents, teaching, learning and evaluation strategies for each particular area or subject are detailed, having as resources the educational platforms such as videos, animations and presentations enrich the educational content and facilitate the understanding of the concept; at the micro-curricular level, the daily activities are planned, defining the didactic resources to be used, the evaluation criteria are established at the level of the didactic units, the technology will improve the interaction in the classroom and personalize the learning process.
Difficulties in understanding and using rational numbers

It aims to investigate how we can contribute to minimizing the countless situations that interfere with the development of fractional activities in EJA - Youth and Adult Education, and to research the development of strategies for working with tools that can act by enabling and making EJAI students feel more comfortable with rational numbers.
The Challenge of Computing Homotopy Groups
In the grand tapestry of mathematics, topology stands out for its unique approach to geometric shapes. It doesn't care about size or angles, but rather how spaces can be continuously deformed into one another, like stretching a clay model without tearing or gluing separate pieces. This seemingly abstract concept holds immense power, unlocking hidden properties of shapes and revealing a universe beyond our everyday perception of space. One of the central ideas in topology is the notion of a homotopy group. Imagine a loop drawn on a surface, like a circle on a sphere or a square on a plane. Homotopy groups classify these loops based on how they can be continuously deformed into one another without breaking the loop or letting it touch the edge of the surface. Intuitively, a loop that can be shrunk to a point without leaving the surface represents a "trivial" element in the group. More intricate loops that cannot be shrunk but can be continuously deformed into each other belong to the same class within the group.
Economic analysis on a small rural property
Rural properties, regardless of size, need strategies for decision-making. Given this context, this study maps and evaluates three sources of resources on a particular rural property, with the aim of describing business management on small rural properties, emphasizing the need for an ideal evaluation of the viability of economic activities, as a strategic management tool bringing data, statements and results achieved, in order to bring a better perception of the agricultural segment to rural properties and bringing data analyzed through mathematical models that can maximize the profits of the property under study. As such, through this study it can be identified that under the current conditions, dairy production is unviable, compared to the other two activities on the property, providing an optimal model for maximizing profit, which would be the joint production of corn and soybeans, thus maximizing profit.
Games, Gambling, and Probability
The goal for this textbook is to complement the inquiry-based learning movement. According to the author, concepts and ideas will stick with the reader more when they are motivated in an interesting way. Topics are presented mathematically as questions about the games themselves are posed.
Teacher Noticing of Pre-Service and In-Service Secondary Mathematics Teachers
In light of increasing demands on teachers and the need to develop teaching-related competences, this book examines the situation-specific skill of teacher noticing in pre-service and in-service secondary mathematics teachers. A video-based test instrument is used to measure teachers' noticing skills in perception, interpretation, and decision-making from both general and mathematics pedagogical perspectives. The aim is to understand the structure and characteristics of teacher noticing across different groups, as well as the influences of teaching experience and opportunities to learn. Three quantitative studies are conducted: two cross-sectional studies with 457 participants, including master's students, early career teachers, and experienced teachers, and one longitudinal study with 175 master's students. The results support the conceptualization of teacher noticing as comprising three facets. They also reveal positive influences of teaching experience on the development of teacher noticing, with in-service teachers outperforming master's students. However, experienced teachers perform similarly to early career teachers in general and worse in certain areas, suggesting saturation or forgetting effects. The longitudinal study finds that interpretation skills facilitate the development of perception and decision-making, emphasizing the knowledge-based nature of teacher noticing.

Guaranteed Computational Methods for Self-Adjoint Differential Eigenvalue Problems
This monograph presents a study of newly developed guaranteed computational methodologies for eigenvalue problems of self-adjoint differential operators. It focuses on deriving explicit lower and upper bounds for eigenvalues, as well as explicit estimations for eigenfunction approximations. Such explicit error estimations rely on the finite element method (FEM) along with a new theory of explicit quantitative error estimation, diverging from traditional studies that primarily focus on qualitative results. To achieve quantitative error estimation, the monograph begins with an extensive analysis of the hypercircle method, that is, the Prager-Synge theorem. It introduces a novel a priori error estimation technique based on the hypercircle method. This facilitates the explicit estimation of Galerkin projection errors for equations such as Poisson's and Stokes', which are crucial for obtaining lower eigenvalue bounds via conforming FEMs. A thorough exploration of the fundamental theory of projection-based explicit lower eigenvalue bounds under a general setting of eigenvalue problems is also offered. This theory is extensively detailed when applied to model eigenvalue problems associated with the Laplace, biharmonic, Stokes, and Steklov differential operators, which are solved by either conforming or non-conforming FEMs. Moreover, there is a detailed discussion on the Lehmann-Goerisch theorem for the purpose of high-precision eigenvalue bounds, showing its relationship with previously established theorems, such as Lehmann-Maehly's method and Kato's bound. The implementation details of this theorem with FEMs, a topic rarely covered in existing literature, are also clarified. Lastly, the monograph introduces three new algorithms to estimate eigenfunction approximation errors, revealing the potency of classical theorems. Algorithm I extends Birkhoff's result that works for simple eigenvalues to handle clustered eigenvalues, while Algorithm II generalizes the Davis-Kahan theorem, initially designed for strongly formulated eigenvalue problems, to address weakly formulated eigenvalue problems. Algorithm III utilizes the explicit Galerkin projection error estimation to efficiently handle Galerkin projection-based approximations.
Cultural Tourism in Porto Seguro-Bahia
The aim of this research is to evaluate the discursive aspects of cultural tourism adverts about the Discovery Coast. This scientific analysis research is based on French Discourse Analysis (DA), which examines the materiality of discourses and analyses the discursive corpus of advertisements promoting the Discovery Coast in an area that covers the municipalities of Porto Seguro, Belmonte, Santa Cruz Cabr獺lia, Eun獺polis and Itabela in the far south of Bahia. Communication is important because in order to promote tourism in a locality, it needs to be publicised in order to attract visitors to it, using media such as magazines, folders and the Internet, which is currently one of the world's most widespread means of communication. For a product to be sold, it needs to be publicised and it is through this publicity that the consumer is persuaded to buy what is being sold. In this way, adverts are essential tools in the dissemination and propagation of tourism products and are used as a vehicle capable of building a product's image.
An Observer's Journey Into the Heart of Universes
This work is based exclusively on the observation of sacred arts: Ngombi or Ngoma (Sacred Harp), Mvet ?kang (Harp Cithare), Masque Punu, Songo (sowing game), Menorah (7-branch candlestick) and Hanoukkia (9-branch candlestick), with the current Calendar as their common point of departure. Mathematical universes are built around the recurring unity of quadrilaterals (square or rectangle) with the trilateral figure (triangle) referring to the pyramid. They are mainly characterized by the conversation of one of the quadrilateral's diagonals into a triangular base, while excluding the second, hence the term concave geometric construction. The inner side of geometric figures is the expression of a dynamism whose evolution is both ascending and descending, under a fractal grip by the action of the arithmetic triplet. Central symmetry, orthogonal symmetry, parallelism, perpendicularity, triangulation, diagonometry and more are just some of the geometric theorems to be found here. Civilizational memories are all revealed as bearing the same geometric framework.
Continuous-Parameter Time Series
This book provides a self-contained account of continuous-parameter time series, starting with second-order models. Integration with respect to orthogonal increment processes, spectral theory and linear prediction are treated in detail. L矇vy-driven models are incorporated, extending coverage to allow for infinite variance, a variety of marginal distributions and sample paths having jumps. The necessary theory of L矇vy processes and integration of deterministic functions with respect to these processes is developed at length. Special emphasis is given to the analysis of continuous-time ARMA processes.

Secure signal transmission
Voice communication is closely linked to everyday life, such as education, e-learning, commerce, politics and the dissemination of information. To maintain security, sensitive data must be protected during transmission. Chaotic systems have become good candidates for cryptography to increase the degree of security. In this book, we focus on the design of a high-security voice communication system using two levels of encryption based on chaotic systems. The first level is chaotic masking, while the second level is scrambling. In the masking level using two methods, the first method is masking using a hybridization between chaotic frameworks (logistic map and tent map), while the second method is based on the Chua chaotic system. At the scrambling level, we use Arnold's map. At receiver level, we use Pecore and Carroll synchronization to recover the encrypted audio signal.

Basic Concepts of Nonlinear Optimization
This textbook is an introduction to nonlinear optimization, which treats mathematical concepts stringently on the one hand, but also motivates them in great detail and illustrates them with 42 figures. Therefore, the book is not only aimed at mathematicians, but also at natural scientists, engineers, and economists who want to understand and apply mathematically sound methods in their field. With just over two hundred pages, the book offers sufficient flexibility to serve as a foundation for various types of lectures on nonlinear optimization. Many geometric approaches for understanding both optimality conditions and numerical methods introduce a new perspective, enriching the existing literature on optimization. This is particularly evident in the detailed treatment of issues arising from different functional descriptions of the same geometry of feasible sets, and the thus motivated introduction of constraint qualifications for deriving derivative-based optimality conditions. This book is the English translation of the second edition of "Grundz羹ge der Nichtlinearen Optimierung" (Springer, 2021) written in German. The translation was done with the help of artificial intelligence. A subsequent revision was performed by the author to further refine the work and to ensure that the translation is appropriate concerning content and scientific correctness. It may, however, read stylistically different from a conventional translation.

Linear Optimization and Duality
Linear Optimization and Duality: A Modern Exposition departs from convention in significant ways. Standard linear programming textbooks present the material in the order in which it was discovered. Duality is treated as a difficult add-on after coverage of formulation, the simplex method, and polyhedral theory. Students end up without knowing duality in their bones.This text brings in duality in Chapter 1 and carries duality all the way through the exposition. Chapter 1 gives a general definition of duality that shows the dual aspects of a matrix as a column of rows and a row of columns. The proof of weak duality in Chapter 2 is shown via the Lagrangian, which relies on matrix duality. The first three LP formulation examples in Chapter 3 are classic primal-dual pairs including the diet problem and 2-person zero sum games.For many engineering students, optimization is their first immersion in rigorous mathematics. Conventional texts assume a level of mathematical sophistication they don't have. This text embeds dozens of reading tips and hundreds of answered questions to guide such students.Features Emphasis on duality throughout Practical tips for modeling and computation Coverage of computational complexity and data structures Exercises and problems based on the learning theory concept of the zone of proximal development Guidance for the mathematically unsophisticated reader.
