Model card for fbnetc_100.rmsp_in1k#
A FBNet image classification model. Trained on ImageNet-1k in timm using recipe template described below.
Recipe details:
A simple RmsProp based recipe without RandAugment. Using RandomErasing, mixup, dropout, standard random-resize-crop augmentation. RMSProp (TF 1.0 behaviour) optimizer, EMA weight averaging Step (exponential decay w/ staircase) LR schedule with warmup Model Details#
