Growing use of deep learning at Google
In 2012, there was not much use of deep neural nets at Google. Over time, we built tools that other teams can pick up and use to solve their problems. The tools were general purpose and were easily repurposed to different domains just by training on different types of data.
What is Deep Learning?– A powerful class of machine learning model
– Modern reincarnation of artificial neural networks
– Collection of simple, trainable mathematical functions
They are loosely based on what we know about the brain
Commonalities with real brains:
-each neuron is connected to a small subset of other neurons
-based on what it sees, it decides what it wants to say
-neurons learn to cooperate to accomplish the task
Each neuron implements a relatively simple mathematical function.
