Deep Learning Kickstart - Training Workshop @ PAPIs Europe

Summary

Deep Learning applications are at the leading edge of the current AI revolution.

TensorFlow is Google’s internally developed framework for deep learning, which has been growing in popularity since it was released as open source in 2015.

Keras is a high-level neural networks API, written in Python and capable of running on top of either TensorFlow, CNTK or Theano. It was developed with a focus on enabling fast experimentation and is now included as a TensorFlow contrib module.

PSQL

Magic words:

psql -U postgres

If run with -E flag, it will describe the underlaying queries of the \ commands (cool for learning!).

Most \d commands support additional param of __schema__.name__ and accept wildcards like *.*
