Learn how to find the best classification model with automated machine learning (AutoML). You'll use the Python SDK (v2) to configure and run an AutoML job. Learning objectives In this module, you'll learn how to: Prepare your data to use AutoML for classification. ...
Tabular Transformers: These models have also shown promise in handling structured data, offering an alternative to traditional methods like random forests and gradient boosting machines for tabular classification tasks. Transformers excel in handling large, complex datasets, and they have been widely adopte...
