WebIt predicts all one class on the validation set or just any particular batch? If it is just a particular batch, maybe how you batch the data is off and all of one class is in that batch. Look at metrics like accuracy and loss. If it is the validation set, I would look into if the training loss is consistently going down. WebCheck how often the other class (es) appear. If one class dominates the others (e.g. one class is 99.9% of the data), this is a problem. Look for "outlier detection" techniques. …
