Deep learning models

Definition

Deep learning models are a subset of machine learning techniques that use neural networks with many layers to analyze and interpret complex data patterns. These models excel in tasks such as image recognition, natural language processing, and spatial mapping by learning features directly from data, reducing the need for manual feature extraction. Their ability to process large datasets makes them invaluable in understanding environments and enhancing augmented and virtual reality experiences.
