Re: TensorFlow DLL for Windows (64 bits)

Postby Antonio Linares » Thu Jun 08, 2017 6:49 pm

Joao,

TensorFlow is a Machine Learning (AI) software developed by Google which is becoming very popular

An open-source software library for Machine Intelligence


https://www.tensorflow.org/

Examples of use:
https://cloud.google.com/blog/big-data/2016/08/how-a-japanese-cucumber-farmer-is-using-deep-learning-and-tensorflow

https://www.theverge.com/2016/1/21/10805398/friends-neural-network-scripts

Possibilities are endless :-)
