Several additional approaches were attempted but deprioritized or entirely eliminated from the final workflow due to lack of positive impact on the validation MAE. Her primary interests lie in theoretical machine learning. She currently does research involving interpretability methods for biological deeplearning models.
To determine the best parameter values, we conducted a grid search with 10-fold cross-validation, using the F1 multi-class score as the evaluation metric. For the classifier, we employ SVM, using the scikit-learn Python module. The SVM algorithm requires the tuning of several parameters to achieve optimal performance.
Cross-validation is recommended as best practice to provide reliable results because of this.
