...Para os meus pais, porque "o valor das coisas não está no tempo que elas duram, mas na intensidade com que acontecem. Por isso existem momentos inesquecíveis, coisas inexplicáveis e pessoas incomparáveis" como vocês! Obrigado por tudo, Filipe Abstract The Retail Banking Industry has been severely affected by fraud over the past few years. Indeed, despite all the research and systems available, fraudsters have been able to outsmart and deceive the banks and their customers. With this in mind, we intend to introduce a novel and multi-purpose technology known as Stream Computing, as the basis for a Fraud Detection solution. Indeed, we believe that this architecture will stimulate research, and more importantly organizations, to invest in Analytics and Statistical Fraud-Scoring to be used in conjunction with the already in-place preventive techniques. Therefore, in this research we explore different strategies to build a Streambased Fraud Detection solution, using advanced Data Mining Algorithms and Statistical Analysis, and show how they lead to increased accuracy in the detection of fraud by at least 78% in our reference dataset. We also discuss how a combination of these strategies can be embedded in a Stream-based application to detect fraud in real-time. From this perspective, our experiments lead to an average processing time of 111,702ms per transaction, while strategies to further improve the performance are discussed. Keywords: Fraud Detection, Stream Computing, Real-Time...

What kind of questions do they ask and what judgments do applicants have to make while answering them? Since 2003, those with real Group Discussion and Personal Interview calls from India’s top bschools have been posting entire and detailed transcripts of their admission interviews immediately after they happen, so that others slotted for later interviews can learn what GDPI is going to be like this year. This book is a collection of dozens of handpicked GDPI experiences from the country’s top bschools during the admission years 2005, 2006, 2007, 2008, 2009 and 2010. In this edition, we have included over 180 GDPI experiences from the admission processes of IIM Ahmedabad, IIM Bangalore, IIM Calcutta, IIM Indore, IIM Lucknow and IIM Kozhikode.
