About

Language

This workshop will be given in English.

Description

The Fin-ML/IVADO Online Workshop is a practical training in machine learning, applied to concrete problems in investments, banking and insurance. Over each week, the workshop will consist of theory in one session, followed by a problem-solving session. There may be work to complete between the sessions. This online workshop will take place over a 10 week period, 1.5 hour per session with a 15 minute break.

Target Audience

Master’s and PhD students and professionals with quantitative training who want to learn about new technologies in data science, machine learning and operations research, with examples applied to problems in investments, banking and insurance.

*The concepts may be interesting to technical professionals that are not from the finance world, although examples and datasets will come from this environment.

Prerequisites

Knowledge of Mathematics & Statistics (Linear Algebra, Probability and Information Theory, Numerical Computation), and Programming (ideally Python) is strongly recommended. The participants can familiarize themselves with Chapters 2 to 4 of the Deep Learning book by Ian Goodfellow and Yoshua Bengio and Aaron Courville (available online deeplearningbook.org)

Objectives

  • Introduce students and professionals to new technologies in machine learning, that are most relevant in the financial sector;
  • Develop an understanding of the challenges and issues of data science applied to investments, banking and insurance;
  • Learn to use computer tools to solve concrete problems;
  • Encourage interdisciplinary knowledge sharing.

Organizers

  • Manuel Morales, Associate Professor, Université de Montréal, Director of Fin-ML
  • Rheia Khalaf, Director of Collaborative Research & Partnerships, Fin-ML
  • Nathalie Sanon, Head of IVADO training program

Week 3

Theory: Alexandre Nguyen

  • Introduction: Forecasting problem

Tutorial: Aden Houssein Aboubaker

  • Comparison between ML and DL applied in Banking (Fraud Detection):
    • Fraud detection dataset: we will do following steps: Exploratory Data Analysis, Data Preprocessing, Model Evaluation and Selection based on good metric adapted to the situation,
    • We will focus on methodological approaches to handle efficiently the problem of unbalanced datasets in a binary classification context for Fraud Detection,
    • Indeed, the problem of unbalanced data is very frequent in the industry and this is why it is now necessary to have in its Data Scientist toolbox the techniques that allow to remedy this,
    • We will see that there are several solutions to remedy this imbalance problem such as: (1.a) choosing the right metric to monitor, (1.b) solutions at the algorithmic level (e.g. introducing a penalty in the cost function, cost-sensitive learning…), (2) selecting a good threshold (e.g. by optimizing threshold using precision/recall graphs), (3) solutions at the data level (under/oversampling, synthetic data…),, and (4) anomaly detection (e.g. Auto-encoders, Isolation Forest…).
