I have trained a model to figure out if an image is right or wrong (just 2 classes) and I have used the guide on keras website for GradCAM . The input images are reshaped to (250, 250) and then normalized by dividing the image numpy array by 255. This is then passed for the training of the model.

Webb12 okt. 2024 · second question: the slowfast model has 2 paths (slow and fast paths) and each path need a specific number of frames from the whole input (for ex if my batch is 64 frames the fast path will need 32 frame only and the slow path will need less “and those frames choosing by a specific skip offset too”, so how could i do this also ? 1 Like WebbContribute to github-zbx/mmaction2 development by creating an account on GitHub.

WebbSlowFast is a new 3D video classification model, aiming for best trade-off between accuracy and efficiency. It proposes two branches, fast branch and slow branch, to handle different aspects in a video. Fast branch is to capture motion dynamics by using many but small video frames. Webbslow_cams = [] for idx in range (guided_gradients.shape [1]): # Get weights from gradients weights = np.mean (guided_gradients [:, idx, :, :], axis= (1, 2)) # Take averages for each …

WebbGradCAM is designed for convolutional neural networks, and is usually applied to the last convolutional layer. GradCAM computes the gradients of the target output with respect to the given layer, averages for each output channel (dimension 2 of output), and multiplies the average gradient for each channel by the layer activations.

WebbThis scalar fulfills the role of label in classification tasks, and generalizes the Grad-CAM technique to nonclassification tasks, such as regression. Grad-CAM uses the reduced output activations of the reduction layer to compute the gradients for the importance map.
