For ReLU networks, the activations usually start out looking relatively blobby and dense, but as the training progresses the activations usually become more sparse and localized. Geoff Tate looks at the shortcomings of ResNet-50 as an inference benchmark in machine learning and considers the importance of image size, batch size and throughput for assessing. GitHub Gist: instantly share code, notes, and snippets. Accuracy increased with unfreezing more Resnet blocks, as more activation layers got to train for specific task [fashion data set]. This paper presents deep residual net architecture that won ImageNet detection and localization, COCO detection and segmentation. Our DCT coefficients are very differently shaped: the Y channel is 8x smaller along each spatial dimension but has 64 frequency channels, resulting in input shape (28, 28, 64). "Using NVIDIA's TensorRT on Tesla GPUs, we can simultaneously inference 1,000 HD video streams in real time, with 20 times fewer servers.

We classified each of these images using ResNet and inspected the results. Deep networks are hard to train because of the notorious vanishing gradient problem-as the gradient is back-propagated to earlier layers, repeated multiplication may make the gradient infinitively small. , use --model=resnet --hparams_set=resnet_50 or --model=xception --hparams_set=xception_base. We also show how Grad-CAM may be combined with existing pixel-space visualizations to create a high-resolution class-discriminative visualization (Guided Grad-CAM). For TSC, this is the deepest architecture with 11 layers of which the first 9 layers are convolutional followed by a GAP layer that averages the time series across the time dimension.
