# Deep Learning: Introduction and Basics

Today we will learn more about how deep learning works and what model types there are used for medical problems.

What we will do today:
* Theory and Practice of Deep Learning
* Introducing different model architectures
* Hands-on practice with in different exercises

Slides used for this session can be downloaded as PDF [here](deep_learning_introduction.pdf).

We will use the Jupyter Notebooks today not over our terminal but in Google Colab.  
Google Colab can be used as a coding environment and provides us with computational resouces like GPUs.  
Please login to your Google account.  

**2 IMPORTANT HINTS:**
1. Please open the notebooks over the links down here. This will first give you a page with a lot of text. 
In the upper right corner there should be a button with "Open with Google Collaboratory". Please click on this.

2. For notebook 01, 02 and the exercise notebooks, please save a copy of them in your Google Drive and work on these copies not in the original notebooks.
For this you open the notebook click on File -> Save a copy in Drive -> wait a few seconds until the copy opens automatically.

Then you can work on the exercises and have fun ! 

We added the notebooks also as files in Git for your to have a look but not to execute them on your laptop.
