Hands-On Deep Learning with Go

Simple example – addition

The easiest way to understand how this all fits together is by building a simple example.

To start, let's implement a simple graph to add two numbers together—basically, this would be: c = a + b:

1. First, let's import some libraries—most importantly, Gorgonia, as follows:

package mainimport (     "fmt"     "log"     . "gorgonia.org/gorgonia" )

2. Then, let's start our main function, like so:

func main() {  g := NewGraph()}

3. To that, let's add our scalars, as shown here:

a = NewScalar(g, Float64, WithName("a"))b = NewScalar(g, Float64, WithName("b"))

4. Then, very importantly, let's define our operation node, as follows:

c, err = Add(a, b)if err != nil {              log.Fatal(err)              }

Note that c will not actually have a value now; we've just ...
