Gat num_heads
WebBy default, we use ``[32, 32]``. num_heads : list of int ``num_heads[i]`` gives the number of attention heads in the i-th GAT layer. ``len(num_heads)`` equals the number of GAT layers. By default, we use 4 attention heads for each GAT layer. feat_drops : list of float ``feat_drops[i]`` gives the dropout applied to the input features in the i-th ...

WebJun 8, 2024 · Description: Training a video classifier with hybrid transformers. This example is a follow-up to the Video Classification with a CNN-RNN Architecture example. This time, we will be using a Transformer-based model ( Vaswani et al.) to classify videos. You can follow this book chapter in case you need an introduction to Transformers (with code). WebIn this example we use two GAT layers with 8-dimensional hidden node features for the first layer and the 7 class classification output for the second layer. attn_heads is the number of attention heads in all but the last GAT layer in the model. activations is a list of activations applied to each layer’s output.
WebDec 13, 2024 · Probability of seeing x heads out of n=10 coin tosses. We started with a simple experiment, tossing a far coin 10 times. And we repeated the experiment 100 times and measured how many successes/heads we observed. We can use the number of successes (heads) observed in many ways to understand the basics of probability.
