The School

Dates: 1-4 September, 2018

Venue: Christ Church, Oxford

The delegates joined our unique School in AI and ML. Following an introduction to data science and a refresher on Python programming on Level39, Canary Wharf, they went up to Oxford to study the theory and practise machine learning on real financial examples.

The delegates networked with other data scientists, fintech industry leaders, and Oxford academics.

They reviewed, learned, and mastered:

  • probability and statistics
  • linear regression methods
  • dimensionality reduction
  • unsupervised machine learning
  • bias-variance tradeoff
  • model and feature selection
  • classification
  • neural nets
  • deep learning
  • recurrent neural networks, including LSTM
  • reinforcement learning
  • current frontiers in AI and ML

The Course

School

Course Design

The course was designed for practitioners by practitioners with a mathematical and computational background. It was meant to build a solid theoretical foundation, which is vital for understanding data science and machine learning.

The emphasis, however, was not on theory but on getting results in practice. As George Pólya put it, mathematics is not a spectator sport!

For this very reason, we used active learning. Practical exercises were provided in unassessed tutorials, and Jupyter-based laboratory sessions.

School

Overview

There were no formal prerequisites for the course, although some familiarity with linear algebra, probability, and optimization theory was a plus. We refreshed the delegates’ memory whenever they needed a refresher.

Those who wished to read up on AI/ML before starting the course were recommented Intelligent Data Analysis by Berthold and Hand, The Elements of Statistical Learning: Data Mining, Inference, and Prediction by Hastie, Tibshirani, and Friedman, and Deep Learning by Goodfellow, Bengio, and Courville. Some of these books are freely available online.

The course began with a review of Python programming, visualization, and libraries.

We reviewed probability and statistics needed for machine learning, examined linear regression methods as a basic example of a supervised machine learning technique, considered dimensionality reduction, unsupervised machine learning, bias-variance tradeoff, model and feature selection, classification, until focussing on neural nets and deep learning (the emphasis of this course).

Deep learning architectures such as deep neural networks, deep belief networks, and recurrent neural networks had been applied to many fields, including computer vision, speech recognition, natural language processing, audio recognition, social network filtering, machine translation, bioinformatics, drug design, and board game programmes, where they had produced results comparable to and, in some cases, superior to human experts.

When you come to our events, we take you on a tour of Level39 and introduce you to members of Level39, their co-founders and potential investors.

Venue

The University of Oxford

Our trainings take place at one of the constituent colleges of the University of Oxford, the oldest university in the English-speaking world and the world’s second-oldest university in continuous operation. Teaching at Oxford goes back as far as 1096.

There are 38 constituent colleges at Oxford and a full range of academic departments organized into four divisions. Christ Church, or Ædes Christi in Latin, is a constituent college of the University of Oxford. It is colloquially known as The House. The college, especially its dining hall, have been featured in the Harry Potter movies.

Sixty-nine Novel Prize winners, four Fields Medalists, and six Turing Award winners have studied, worked, or held visiting fellowships at the University of Oxford.

For all participants, accommodation on Oxford’s campus was provided. They joined a distinguished company of scholars who lived in these very rooms: Lewis Carroll, Albert Einstein, William Ewart Gladstone, Robert Hooke, John Locke, Sir Robert Peel, and others.
