The main difference between deep learning and geometric deep learning lies in the data structures they operate on.
1. Deep Learning: Traditional deep learning methods operate on grid-like data structures, such as images or sequences. These methods assume that data points are independent and identically distributed, and they leverage neural networks with layers of neurons to learn hierarchical representations from the data. Deep learning models excel at tasks like image classification, natural language processing, and speech recognition.
2. Geometric Deep Learning: Geometric deep learning, on the other hand, focuses on learning from and processing non-grid structured data, such as graphs, manifolds, or point clouds. It extends deep learning to irregular and structured domains where data points are not necessarily independent. Geometric deep learning methods incorporate the underlying geometric structure of the data, allowing the models to capture relationships, patterns, and symmetries present in the data. This makes geometric deep learning well-suited for tasks like graph analysis, molecule modeling, social network analysis, and 3D shape understanding.
In summary, while traditional deep learning operates on grid-like data, geometric deep learning extends deep learning to handle non-grid structured data, enabling the modeling of complex relationships and patterns inherent in graphs and other structured domains.
