Web我有一個梯度爆炸問題，嘗試了幾天后我無法解決。我在 tensorflow 中實現了一個自定義消息傳遞圖神經網絡，用於從圖數據中預測連續值。每個圖形都與一個目標值相關聯。圖的每個節點由一個節點屬性向量表示，節點之間的邊由一個邊屬性向量表示。在消息傳遞層內，節點屬性以某種方式更新 ... WebJul 18, 2024 · When the gradients vanish toward 0 for the lower layers, these layers train very slowly, or not at all. The ReLU activation function can help prevent vanishing gradients. Exploding Gradients. If the weights in a network are very large, then the gradients for the lower layers involve products of many large terms. WebFor example, if only 25% of my kernel's weights ever change throughout the epochs, does that imply an issue with vanishing gradients? Here are my histograms and distributions, is it possible to tell whether my model suffers from Vanishing gradients from these images?
