About this paper
David Eigen, Marc'Aurelio Ranzato, Ilya Sutskever
A Deep Mixture of Experts (DMoE) framework enables scalable neural network architectures by dynamically activating different processing paths for each input. It learns to factor distinct aspects of data, such as location and content on image tasks, while efficiently utilizing a large number of expert combinations.
Key insights
- The DMoE automatically learns factored representations, with different layers specializing in distinct aspects of the input data (e.g., 'where' vs. 'what' in image recognition).
- Dynamic, input-dependent activation of network components facilitates conditional computation, allowing only relevant parts of a large model to be engaged for a given input.
- The gating assignment constraint effectively promotes diverse expert usage, ensuring that the numerous potential expert combinations are actively leveraged during training.
