This is the repository for the hands-on session of the Tutorial on Sequence-Aware Recommenders to be held at ACM RecSys 2018 in Vancouver.

All the additional material about the tutorial is hosted at this page.

You have two options to run the code contained in this repository:

1. Setup a new environment on your local machine and run the code locally (highly recommended).
2. Launch a new Binder instance by clicking on this badge .

While we all know that setting up a new local environment is a slightly tedious process, Binder instances have strict resource limits (1-2GB of memory, max 100 concurrent users per repository). Also beware that Binder sessions automatically expire after 10 minutes of inactivity!
So we highly recommend to set up a new local environment in advance by following the Setup instructions.

First of all, clone this project to your local machine.

Now you need to set up a new python3 environment. We will use Anaconda/Miniconda for doing so. If you don't have Anaconda/Minicoda already installed on your machine, download it here (Python 3 version).

After that, install the environment for this hands-on by running:

conda env create --file environment.yml

Then activate the environment with source activate srs or conda activate srs, and install a new iptyhon kernel by running:

python -m ipykernel install --name srs

Finally, launch the Jupyter Notebook with

jupyter notebook --port=8888

and open it your browser at the address localhost:8888. (Beware, if port 8888 is already taken by another service, jupyter notebook will automatically open on a different one. Check out the startup log!).

The notebooks used in this hands-on are listed in the main directory of this project, as shown below:

Click on the name of the notebook to open it in a new window. The name of each running notebook is highlighted in green (in the screen above, the notebook 00_TopPopular is the only one running).

Before starting to execute the notebook cells, you have to ensure that the kernel is properly set to srs, like in the screen below:

If it's not your case, change the kernel to srs by clicking on Kernel > Change kernel > srs in the menu bar, as shown below:

NOTE: this requires the installation of the srs kernel, as explained in the Setup instructions.

You can now start running the cells in the notebook! Yay!

We want to sincerely thank Umberto Di Fabrizio for developing large sections of this repository back when he was a MSc student at Politecnico di Milano. Great job Umberto!
