Introduction to Deep Learning for Medical Researchers

İstinye University (Cevizlibağ), Tuesday, Wednesday, and Thursday, 4:30-6:30PM

This repository contains a series of presentations, Google Colaboratory notebooks, and supporting code and provides an introduction to machine learning and deep learning tools and techniques. The material, created in collaboration with Prof. Çetin Kaya Koç, was a short-course for medical researchers at İstinye University, Turkey. This class introduces basic and advanced techniques, with an emphasis on tools, model creation, and model validation.

The course is split into 11 one-hour modules. All computation is done on the cloud using free Google Colaboratory notebooks and free/open-source software: Python and PyTorch. Contents include:
