Residual States:forward过程中保存的临时变量,如激活值Activations,临时缓冲区Temporary buffers,碎片化的存储空间Memory Fragmentation,在反向传播时会逐渐释放。 接下来的ZeRO-DP和ZeRO-R则分别对这两部分的显存占用进行优化;ZeRO-offload和ZeRO-Infinity则是将显存占用offload到CPU和NVME中;ZeRO++则是解决集群低带宽且显存...

On average beta seems to be about -0.005 in residual layers. Low learning rate and starting from already trained weights probably affected the results, but I can't run any longer runs on my computer. Also earlier I wrote that batch norm mean can be modified to include beta. It's true,...

This target model consists of 32 residual blocks with width 4096. We form the small proxy model by shrinking width to 256, resulting in roughly 40 million trainable parameters, 168 times smaller than the target model. HPs were then determined by a random search on the proxy model. The total...
