Predict football punt and kickoff return yards with fat-tailed distribution using GluonTS

Flipboard

There are around 3,000 and 4,000 plays from four NFL seasons (2018–2021) for punt and kickoff plays, respectively. Models were trained and cross-validated on the 2018, 2019, and 2020 seasons and tested on the 2021 season. To avoid leakage during cross-validation, we grouped all plays from the same game into the same fold.

Machine Learning Strategies Part 07: Addressing Bias and Variance

Mlearning.ai

For example, if you are using regularization such as L2 regularization or dropout with your deep learning model that performs well on your hold-out-cross-validation set, then increasing the model size won’t hurt performance, it will stay the same or improve. The only drawback of using a bigger model is computational cost. Ng, Andrew.

What a data scientist should know about machine learning kernels?

Mlearning.ai

This is often done using techniques such as cross-validation or grid search. Hyperparameter tuning is the process of finding the optimal values for these hyperparameters to maximize the performance of the algorithm. There are several approaches to hyperparameter tuning for kernel-based algorithms, including: 1.
