DSD: Regularizing Deep Neural Networks with Dense …

providing enough model capacity. We propose DSD, a dense-sparse-dense training flow, for regularizing deep neural networks. In the first D step, we train a dense network to learn which connections are important. In the S step, we regularize the network by pruning the unimportant connections and retrain the network given the sparsity constraint.

The dense phase has a viscosity similar to that of a gas, but a density closer to that of a liquid. Because of its unique properties, dense phase has become attractive for transportation of natural gas. Pipelines have been built to transport natural gas in the dense phase region due to its higher density.

Dense phase is a fourth (Solid, Liquid, Gas, Dense) phase that cannot be described by the senses. The word "fluid" refers to anything that will flow and applies equally well to gas and liquid. Pure compounds in the dense phase or supercritical fluid state normally have better dissolving ability than do the same substances in the liquid state.

The term dense phase has become an ambiguous because no universally accepted definition appears to exist. For reference purposes, therefore, some definitions need to be established to identify the modes of flow that can exist in pneumatic conveying. In the context of this work, the term dense phase is used to cover all non-suspension flow regimes.

Dense Phase Pneumatic Conveying – Cyclonaire

Dense phase pneumatic conveying is a relatively low-speed system where the material is not suspended in the air stream. The low velocity of dense phase means less wear and tear on both the system and the materials being conveyed. The velocity is typically set between 400 ft./min. and 1,000 ft./min., though there are several forms of dense ...
