  1. 21. A Comparative study of data splitting algorithms for machine learning model selection

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Delwende Eliane Birba; [2020]
    Keywords : K-fold; cross-validation; Kennard-Stone algorithm; data splitting; bootstrap; overfitting; SPXY; k-faldig korsvalidering; korsvalidering; Kennard-Stone-algoritm; datapartitionering; bootstrap; överanpassning; SPXY;

    Abstract : Data splitting is commonly used in machine learning to split data into a train, test, or validation set. This approach allows us to find the model hyper-parameter and also estimate the generalization performance. In this research, we conducted a comparative analysis of different data partitioning algorithms on both real and simulated data. READ MORE
