Bankers Like Us: Dispatches from an Industry in Transition
by Leda GlyptisThis book will resonate with anyone no matter where you reside on this journey, whether newbie or old guard. If you want to be part of this change, you need to understand all about the messy middle that Leda so expertly describes in this book. If you read this book and it doesn’t resonate, then I suggest you think about stepping aside. — Curt Queyrouze, President, Coastal Community Bank The world is going digital, and so is banking—in fits, starts, and circles. Why is it so hard? Why is the industry constantly getting in the way of its own technological progress and what can we do about it all? This book looks at the human and structural obstacles to innovation-driven transformation and at the change in habits, mindsets and leadership needed for the next stage of the digital journey and argues that this change will be brought about, not by external heroes and saviours, not by a generation yet to be born, but people just like us. People who understand the industry and its quirks. Bankers who have the grit, determination and energy to drive change. Bankers like us. This book celebrates and chronicles the shared experience of bankers like us. It starts with a ‘this is who we are’ piece, including the author’s trench credentials. It then presents an overview of corporate culture (this is what we deal with and a few ideas on how to handle it), as well as a piece on why transformation is so difficult and so many get it wrong; a piece on the challenges our lack of diversity brings or compounds, and a hopeful look-ahead on what a team of principled, dedicated folks can do despite everything.
Banking 4.0: The Industrialised Bank of Tomorrow
by Mohan BhatiaThis book shows banking professionals how to leverage the best practices in the industry to build a structured and coordinated approach towards the digitization of banking processes. It provides a roadmap and templates in order to industrialize the financial services firm over iterative cycles.To achieve the planned business and revenue results at the optimal costs, the digital transformation has to be calibrated and coordinated across both the front and back office, scaled and timed against external innovation benchmarks and Fintechs. To this end, data collection and evaluation must be ingrained, banking-specific artificial intelligence methods must be included, and all digitization approaches must be harmonized on an iterative basis with the experience gained. Spread over several chapters, this book provides a calibration and coordination framework for the delivery of the digital bank 4.0.
Banking on (Artificial) Intelligence: Navigating the Realities of AI in Financial Services
by Theodora LauThere is no lack of hype around artificial intelligence. We have only begun to scratch the surface of what this powerful technology can do. While tech and financial services become more intertwined, cutting through the noise has become more difficult but also more crucial. As a technology, AI is essential to advancing innovation, to creating efficiencies, and enhancing productivity while capturing opportunities by both incumbent financial institutions as well as fintechs. But it also comes with risks and potential for biases and disinformation, that can deepen inequalities and erode trust in our society. Responsible innovation must become part of our DNA and not as an afterthought. This book provides a tailored overview of what AI specifically means for financial services, a highly regulated yet also disrupted industry. It investigates the current state of AI applications in financial services today along with the state of funding and partnerships between tech and banking industries. It also examines the key pillars of responsible AI and the importance of keeping humans in the loop. The book takes a deep dive into the use cases in the financial services industry, the challenges and opportunities, and the fragmented regulatory landscape. How can we effectively assess risks, and balance innovation and customer centricity with trust in AI in financial services? Can smaller organizations reap the benefits of the technology? How can institutions deploy AI responsibly and securely, and promote a fairer and more equitable future for more people? While data is about bits and bytes, the realities of AI is very much human. This book will help spark dialogue and collaboration as we journey into the future.
Bankruptcy Prediction through Soft Computing based Deep Learning Technique
by Arindam Chaudhuri Soumya K. GhoshThis book proposes complex hierarchical deep architectures (HDA) for predicting bankruptcy, a topical issue for business and corporate institutions that in the past has been tackled using statistical, market-based and machine-intelligence prediction models. The HDA are formed through fuzzy rough tensor deep staking networks (FRTDSN) with structured, hierarchical rough Bayesian (HRB) models. FRTDSN is formalized through TDSN and fuzzy rough sets, and HRB is formed by incorporating probabilistic rough sets in structured hierarchical Bayesian model. Then FRTDSN is integrated with HRB to form the compound FRTDSN-HRB model. HRB enhances the prediction accuracy of FRTDSN-HRB model. The experimental datasets are adopted from Korean construction companies and American and European non-financial companies, and the research presented focuses on the impact of choice of cut-off points, sampling procedures and business cycle on the accuracy of bankruptcy prediction models. The book also highlights the fact that misclassification can result in erroneous predictions leading to prohibitive costs to investors and the economy, and shows that choice of cut-off point and sampling procedures affect rankings of various models. It also suggests that empirical cut-off points estimated from training samples result in the lowest misclassification costs for all the models. The book confirms that FRTDSN-HRB achieves superior performance compared to other statistical and soft-computing models. The experimental results are given in terms of several important statistical parameters revolving different business cycles and sub-cycles for the datasets considered and are of immense benefit to researchers working in this area.

Baseball Hacks: Tips & Tools for Analyzing and Winning with Statistics
by Joseph AdlerBaseball Hacks isn't your typical baseball book--it's a book about how to watch, research, and understand baseball. It's an instruction manual for the free baseball databases. It's a cookbook for baseball research. Every part of this book is designed to teach baseball fans how to do something. In short, it's a how-to book--one that will increase your enjoyment and knowledge of the game. So much of the way baseball is played today hinges upon interpreting statistical data. Players are acquired based on their performance in statistical categories that ownership deems most important. Managers make in-game decisions based not on instincts, but on probability - how a particular batter might fare against left-handedpitching, for instance. The goal of this unique book is to show fans all the baseball-related stuff that they can do for free (or close to free). Just as open source projects have made great software freely available, collaborative projects such as Retrosheet and Baseball DataBank have made great data freely available. You can use these data sources to research your favorite players, win your fantasy league, or appreciate the game of baseball even more than you do now. Baseball Hacks shows how easy it is to get data, process it, and use it to truly understand baseball. The book lists a number of sources for current and historical baseball data, and explains how to load it into a database for analysis. It then introduces several powerful statistical tools for understanding data and forecasting results. For the uninitiated baseball fan, author Joseph Adler walks readers through the core statistical categories for hitters (batting average, on-base percentage, etc.), pitchers (earned run average, strikeout-to-walk ratio, etc.), and fielders (putouts, errors, etc.). He then extrapolates upon these numbers to examine more advanced data groups like career averages, team stats, season-by-season comparisons, and more. Whether you're a mathematician, scientist, or season-ticket holder to your favorite team, Baseball Hacks is sure to have something for you. Advance praise for Baseball Hacks: "Baseball Hacks is the best book ever written for understanding and practicing baseball analytics. A must-read for baseball professionals and enthusiasts alike."-- Ari Kaplan, database consultant to the Montreal Expos, San Diego Padres, and Baltimore Orioles"The game was born in the 19th century, but the passion for its analysis continues to grow into the 21st. In Baseball Hacks, Joe Adler not only demonstrates thatthe latest data-mining technologies have useful application to the study of baseball statistics, he also teaches the reader how to do the analysis himself, arming the dedicated baseball fan with tools to take his understanding of the game to a higher level."-- Mark E. Johnson, Ph.D., Founder, SportMetrika, Inc. and Baseball Analyst for the 2004 St. Louis Cardinals
Bases de Hacking: um guia de iniciantes ao hacking ético e aos testes de penetração
by Adidas WilsonOriginalmente, o termo “hacker” referia-se a um programador que tinha competências a nível de sistemas operativos e código de máquina. Nos nossos dias, é qualquer pessoa que incorra em atividades de hacking. Hacking é o ato de mudar as funcionalidades de um sistema de forma a atingir um objetivo que não está no propósito original do criador. A palavra “hacking” é normalmente percebida de forma negativa, especialmente por pessoas que não percebem o trabalho de um hacker ético. No mundo do hacking, os hackers éticos são boas pessoas. Qual o seu papel? Usam o seu vasto conhecimento de computadores para o bem em vez do mal. Procuram falhas de segurança nos sistemas da organizações e negócios para prevenir atores maliciosos de tomarem vantagem dos mesmos. Para alguém que adora o mundo da tecnologia e dos computadores, seria inteligente considerar uma carreira de hacking ético. Você é pago (quantia interessante) para quebrar os sistemas. Começar não será como ir dar um passeio ao parque – tal como qualquer outra carreira. No entanto, se for determinado, verá que irá conseguir uma carreira lucrativa. Quando decidir iniciar-se nesta jornada, terá de cultivar a paciência. O primeiro passo para muitas pessoas é normalmente obter um curso em ciências de computadores. Pode também obter uma certificação A+ (CompTIA) – tem de fazer e passar a dois exames diferentes. Para conseguir fazer o teste de qualificação, precisa de ter pelo menos 500 horas de experiência em computação prática. A experiência é requerida, e uma qualificação em CCNA ou Network+ para avançar na carreira.
