Why it exists

Suites and small nets need MSE+SGD and tween hooks without inventing an external trainer.

What it is

MSE/MSEGrad, SGD, Step, ApplyTween/StepTween, StepMesh. No QAT dual path — storage dtype is truth.

Go example

examples/31-training/main.go

Run:cd welvet/examples/31-training && source ../env.sh && go run .
package main

import (
	"fmt"

	"github.com/openfluke/welvet/architecture"
	"github.com/openfluke/welvet/core"
	"github.com/openfluke/welvet/layers/dense"
	"github.com/openfluke/welvet/runtime/forward"
	"github.com/openfluke/welvet/runtime/training"
)

func main() {
	g := architecture.NewGrid(1, 1, 1, 1)
	l, _ := dense.New(4, 4, core.ActivationLinear, core.DTypeFloat32)
	_ = dense.Place(g, 0, 0, 0, 0, l)
	fwd, _ := forward.Forward(g, core.NewTensor[float32](1, 4))
	loss, err := training.Step(fwd, core.NewTensor[float32](1, 4), 1e-2)
	fmt.Println(loss, err)
}
