Visão geral

Goro é uma biblioteca de aprendizado de máquina de alto nível para o Go Build on Gorgonia. O objetivo é ter a mesma sensação que Keras.

Uso

// create the 'x' input e.g. mnist image
x := NewInput ( "x" , [] int { 1 , 28 , 28 })

// create the 'y' or expect output e.g. labels
y := NewInput ( "y" , [] int { 10 })

// create a new sequential model with the name 'mnist'
model , _ := NewSequential ( "mnist" )

// add layers to the model

// fit the model

// fit the model with a batch
