验证步数 Validation Step,计算验证集Loss的间隔步数;为0时不开启验证,没有相关指标。 repetition_penalty 生成样本时的长度惩罚系数。 temperature 生成样本时的temperature。 kl_coeff 对reward增加KL-Penalty的系数。 Checkpoint保存个数 训练过程最终要保存的Checkpoint个数,Checkpoint保存会增加训练时长。 Checkpoint保存...

You did not mention the size of the training, validation, and test. The size of the data you use is very important to be as big enough to represent the real distribution of the data, in training, validation, and the test. On the other hand, the way you sample the data should be do...

The train and validation accuracy improves throughout training, and the train loss decreases. The number of validation samples is the same as the number of train samples. After the training was accomplished, by using the model.evaluation(X,Y) function, the loss was s...
model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy']) history = model.fit(x_train, y_train,batch_size=batch_size, epochs=epochs, verbose=1, validation_split=0.1) 话不多说,我们直接来看结果: score = model.evaluate(x_test, y_test, ...
to train GatorTron models by leveraging both data-level and model-level parallelisms implemented by the Megatron-LM package43. We monitored the training progress by training loss and validation loss and stopped the training when there was no further improvement (i.e., the loss plot became flat...
