Find here the material of the first three weeks of the lecture course. A fourth draft of the lecture notes from 2013 and 2017 together with the exam questions can be found here. Two ipython notebooks on learning arbitrages and simulating semi-martingales are provided. Several examples from my course Machine Learning in Finance are used to illustrate concepts and to demonstrate the effectiveness of machine learning technology in Finance.
