validation loss increasing after first epoch
The best model was saved at this instant. I'm using model.fit_generator() to … Press J to jump to the feed. This decay policy follows a time-based decay that we’ll get into in the next section, but for now, let’s familiarize ourselves with the basic formula, Suppose our initial learning rate = 0.01 and decay = 0.001, we would expect the learning rate to become, 0.1 * (1/ (1+0.01*1)) = 0.099 after the 1st epoch. The second reason you may see … Usually with every epoch increasing, loss goes lower and accuracy goes … validation loss increasing - bullseyevideomarketing.com I am using SGD optimizer. I was training the Le-Net 5-LeCun et al architecture on the Cifar-10 dataset for some tensorflow practice and I noticed that my Validation loss and accuracy starts to increase after a point and then starts to yo-yo around the point while my training loss keeps decreasing. But with val_loss (keras validation loss) and val_acc (keras validation accuracy), many cases can be possible like below: val_loss starts increasing, val_acc starts decreasing. If you’re somewhat new to Machine Learning or Neural Networks it can take a bit of expertise to get good models. But validation loss and validation acc decrease straight after the 2nd epoch itself. The overall testing after training gives an accuracy around 60s. I've already cleaned, shuffled, down-sampled (all classes have 42427 number of data samples) and split the data properly to training (70%) / validation (10%) / testing (20%). In the example from the previous section, a default batch size of 32 across 500 examples results in 16 updates per epoch and 3,200 updates across the 200 epochs. validation loss increase after
