Day #88 - Metrics Optimization

Loss vs Metric
  • Metric - Function which we want to use to evaluate the model. Maximum accuracy in classification
  • Optimization Loss - Easy to optimize for given model, Function our model optimizes. MSE, LogLoss
  • Preprocess train and optimize another metric - MSPE, MAPE, RMSLE
  • Optimize another metric postprocess predictions - Accuracy, Kapps
  • Early Stopping - Stop traning when models starts to overfit
 Custom loss functions

Accuracy Metrics





Happy Coding and Learning!!!
