Workshops descriptions

Developing a small application with git

Speaker: Ignasi Fosch (@ignasi-fosch)
Language: English
Description: In this workshop, the attendees will participate in collaborative developing a small simple application using git and GitHub for the workflow. The goals of the exercise is to practice some simple concepts about contributing code.
Level: Beginner
Requirements:

• Git installed
• Some virtual environment with Python 3.6 and pytest setup
• GitHub account created

Introduction to pytorch

Speaker: Bartek Skorulski
Language: English
Description: Why is it worth to know pytorch? Pytorch is a machine/deep learning library for python mainly developed by Facebooks’s AI Research Group. SInce pytorch's models are just like other python programs, it quite easy to write and debug them. Hence pytorch is great for research and experiments. Moreover, with new version 1.0, pytorch introduce "script mode" that aims to become also a tool for writing production code.

In this short workshop we give a quick and dirty introduction to pytorch. You will have an opportunity to build, train and evaluate few forward feed neural networks. We start with a simple single layer neural networks and finish with convolutional ones.
Level: Intermediate
Requirements:

• We assume that you are familiar with python, have some basic knowledge about neural network.
• You will get the best experience if you bring a notebook with access to python (I'll use version 3.6) with numpy, pandas, jupyter, pytorch, matplotlib, pillow and opencv.
• Guide to install Pytorch.

Data analysis with Jupyter Notebook, Pandas and Plotly

Speaker: Natàlia Padilla (@nataliasirera) and Laura Pérez (@laura-perez-mayos) (@PyLadiesBCN)
Language: English
Description: A hands-on session where you will learn how to analyze data with Jupyter Notebook, Pandas and Plotly. This will be a guided workshop, suitable for both experienced users and beginners with an interest in data analysis.
Level: Beginner
Requirements: a laptop + Jupyter + Pandas + Plotly + an appetite for learning!
Installation:
• Option 1: Install Anaconda anaconda.com/download

Mirror, mirror on the wall, who is the fairest of them all? (Introduction to OpenCV)

Speaker: Ismael Benito (@ismansiete)
Language: English
Description: An introduction to OpenCV for NumPy-Scipy-Matplotlib stack users. Starting with Anaconda pre-compiled versions, specially from Menpo project (https://anaconda.org/menpo/opencv3). Covering inputs and outputs, from basic image handling, such as: 'imread', 'imshow', 'imwrite', etc; to video streams. Some basics in color treatment and thresholding techniques. Also, fundamentals of image warping and cropping. Finally, a small project to be able to find a specific object, for example a QR Code, in a scene and trimmed it.
Level: Intermediate
