Nettet9. des. 2024 · Learning Rate 又稱為學習率,Learning Rate對模型梯度下降的學習影響重大,如果Learning Rate太小,網路容易訓練緩慢,Learning Rate太大又容易無法收斂. 而在訓練神經網路很容易忽略learning rate 的設計,畢竟learning rate 對整體的效果很難有立即見效的效果,但是設計一個 ... Nettet21. jan. 2024 · 2. Use lr_find() to find highest learning rate where loss is still clearly improving. 3. Train last layer from precomputed activations for 1–2 epochs. 4. Train last layer with data augmentation (i.e. precompute=False) for 2–3 epochs with cycle_len=1. 5. Unfreeze all layers. 6. Set earlier layers to 3x-10x lower learning rate than next ... Nettet28. jun. 2024 · The former learning rate, or 1/3–1/4 of the maximum learning rates is a good minimum learning rate that you can decrease if you are using learning rate decay. If the test accuracy curve looks like the above diagram, a good learning rate to begin from would be 0.006, where the loss starts to become jagged. university of pennsylvania jobs hospital
