I observed that after 2 epochs, my validation loss start to increase, but my validation accuracy and f1 score still increases too. I have tried with 2 different seed but I observe the same effect. How do I know if I am overfitting? Should I perform early stopping?
WebGPT2 [also known as alanine transaminase 2 (ALT2)] is one of two related transaminases that catalyze the reversible addition of an amino group from glutamate to pyruvate, yielding alanine and α-ketoglutarate. WebGPT2 is expressed in brain and is in the pathway to generate glutamate, an excitatory neurotransmitter. Functional assays of recombinant wild-type and mutant ALT2 proteins …
