Deep Learning (DL)

Uses multi-layered neural networks to learn complex data representations

Overview

A subfield of machine learning that utilizes artificial neural networks with multiple layers ("deep") to learn hierarchical representations of data. These deep neural networks are capable of automatically extracting complex features from raw data, enabling them to achieve state-of-the-art performance in various tasks, such as image recognition, natural language processing, speech recognition, and generative modeling. Effective training of deep learning models typically requires substantial computational resources, large datasets, and careful tuning of model architecture and parameters.
