the algorithm was produced by hinton in 2022 , using two forward passes to minic the learning in the cortex at sleeping (hinton statement).
Forward Forward Algorithm Paper
use contrastive learning , positive and negative pass including label of image correctly in positive and wrong label in negative images.
- use 2 layer (512) network with softplus function (smoother than ReLU)
loss of testset 0.67% and accuracy 93.27%
