Join us in N RC 2100 or on Teams!\n\nMachine Learning Workshop: Imbalanced Data Strateg ies\n\nPresenter: Dr. Evan Krell (Naval Research Lab - Marine Meteorology Division)\n\nAbstract: A major challenge in machine learning is dealing wi th imbalanced datasets. That is\, where the dataset does not have an equal number of samples from each class. In some situations\, the dataset can b e very imbalanced because of the actual rarity of certain events\, so clas s balance can not be obtained through additional sampling. For example\, t o train a model for predicting hurricanes there are very few hurricane exa mples compared to a massive amount of non-hurricane examples. This makes i t difficult to model extreme events.\n\nTo deal with this\, several class balancing methods have been proposed that have become very popular: Random Undersampling\, Random Oversampling\, SMOTE\, and weighted loss functions . While they can be effective at improving skill at predicting the minorit y class\, they have some major disadvantages. Mainly\, the output probabil ity loses any statistical meaning.\n\nIn this workshop\, I show that these data balancing methods might not do what you think they are doing and tha t there is another\, simpler\, alternative for tuning models under class i mbalance that is applied after training the model so that the original pro babilities that represent the training distribution are maintained.\n\n[ci d:5072f664-a02f-4e57-b816-c16e4d6038b1]\n\n_______________________________ _\n\niCORE Workshops are bi-weekly starting at 4:00pm.
