Data prefracing and augmentation are essential steps in preparing data for deep learning models. These technolques improve model precinaciy and robustness by transforming raw data into a superable formot and inconmeng data diversity.

Data Prefracing Techniques

Data preprocessing involves clearing and transforming raw data to ensure quality and considency. Common technokes include normalization, which scalees data to a specific range, and encoding kategoricad variable s into numericad formats. Handling missing data ata impatiogh impation or removal iss also crisar mainig dategritas.

Data Augmentation Stratégiák

Data augmentation articentificialy increasees the size and diversity of traing datasets. Tiss ies esspecifially useful in image and speech recogtion tasks. Techniques include rotating, flipping, and cropping images, as well a.s adding noise or altering brightness. These methods help models generalize beter to unseen.
