Table 3 The experimental results of learning rate adjustment.
From: Channel equalization in ultraviolet communication based on LSTM-DNN hybrid model
Learning rate | The number of training epochs required to reach convergence | The final accuracy of the test set | Stability of loss reduction |
|---|---|---|---|
0.0001 | 400 | 91.2% | Significant fluctuations, occasional rebound |
0.00005 | 450 | 92.5% | Stable decline, slightly fluctuating |
0.00002 | 500 | 93.1% | Steady decline without significant rebound |
