Web10 de mar. de 2024 · Training sample numbers = 1000 Mini batch size = 100 Within each mini batch, I saved the delta of gradient for each sample, and took average over the 100 samples, and then updated the weight. So the delta of weights are calculated for 100 times, but weights are only updated once for each mini batch. dr victoria bateman twitter
