WebWhat I have noticed is that the training accuracy gets stucks at 0.3334 after few epochs or right from the beginning (depends on which optimizer or the learning rate I'm using). So yeah, the model is not learning behind 33 percent accuracy. Tried learning rates: 0.01, 0.001, 0.0001 – Mohit Motwani Aug 17, 2024 at 9:34 1 WebDec 18, 2024 · $\begingroup$ I see you're using binary cross-entropy for your cost function. For multi-class classification you could look into categorical cross-entropy and categorical accuracy for your loss and metric, and troubleshoot with sklearn.metrics.classification_report on your test set $\endgroup$ WebA metric is a function that is used to judge the performance of your model. Metric functions are to be supplied in the metrics parameter when a model is compiled. A metric function is similar to an objective function, except that the results from evaluating a metric are not used when training the model. You can either pass the name of an ... tower prices
