Hallo everyone,

Our March meetup in 2019 will be hosted by OLX.
Doors open at 6:45 PM and the talks are going to start at 7:15 PM.
Food and Drinks are provided.

The Schedule for the evening:

Talk 1: 35 mins
Title: Image classification at scale
Speaker: Alexey Grigorev

At people upload 3 mln images per day, at 1.5 mln,
and in total across all OLX sites it can easily be tens of millions
images daily.
It is important for us to know what is on these images right after
they are uploaded, and we use deep learning classification models
for that.
Serving deep learning models is challenging at this scale. In this talk
we will present our image processing infrastructure. We will
cover all steps of model lifecycle: from how the models are trained
to how they are deployed to our kubernetes cluster.

Speaker Bio:
Alexey Grigorev is a data scientist and machine learning engineer
with more than 8 years of professional experience. Currently Alexey works as a data scientist at OLX. His areas of expertise are machine learning and text mining.

Talk 2: 35 mins
Title: How autonomous driving can be tackled with a single neural network using Python and Tensorflow
Speaker: Markus Hinsche

Deep networks can be trained on demonstrations of human driving to learn to follow roads and avoid obstacles. This is possible with a single end-to-end network learning all the parts of the driving at once. I will give a short introduction to autonomous driving stacks and guide you through the implemention of this network which was introduced in the paper "End-to-end Driving via Conditional Imitation Learning". We open-sourced our implementation ( and wrote a Medium post (

Speaker Bio:
Markus Hinsche is a Software Engineer working on Machine Learning at Merantix and one of the rare breed of people actually from the Berlin area. He is eager to explore new topics every day. To satisfy this hunger for the unknown, Markus worked at various startups after receiving his Master's degree in IT Systems Engineering at Hasso Plattner Institute in Potsdam.
