在计算 validation loss的时候用的神经网络 其实比计算training loss 的时候是有进步的, 在没有overfitting 的情况下。所以validation loss 会小于 training loss 3。由于数据本身分布(data distribution)的原因,分配到 validation 数据集太小,或者分到 validation 的数据太简单。 refer to: Why is my validation ...
前者是培训损耗,后者是验证损耗
I'm training a unet model on the TACO dataset, and I'm having problems with my output. My validation loss is quite a bit lower than my training loss, and I'm not entirely sure if this is a good thing. Since the TACO dataset is a COCO format dataset with 1500 images...
但是总体来说 validation略微回升也是比较常见的
I have used the Transformer model to train the time series dataset, but there is always a gap between training and validation in my loss curve. I have tried using different learning rates, batch sizes, dropout, heads, dim_feedforward, and layers, but they don't work. Can an...

Getting the validation loss during training seems to be a common issue: #7871 #171 #271 #5694 #1093 The most common 'solution' is to set workflow = [('train', 1), ('val', 1)]. However, in all the above mentioned issues the same error occ...
Getting the validation loss during training seems to be a common issue: #1711 #1396 #310 The most common 'solution' is to set workflow = [('train', 1), ('val', 1)] . But when I do this, while adjusting the samples_per_gpu configuration, ...
The section of most interest to us here is in the training loop section, just above the bottom you will see how the loss parameters are calculated. The training loss is calculated over the entire training dataset. Likewise, the validation loss is calculated over the entire validation dataset. ...
In addition to training, this function also prints training progress information, as well as a plot of the training and validation loss over time. Args: learning_rate: A `float`, the learning rate. steps: A non-zero `int`, the total number of training steps. A training step ...
