Hace 1 día · The impurity sulfur in lead–zinc-bearing hematite–limonite ore mainly exists in the form of galena, sphalerite, pyrite, and natural sulfur, and deep reduction roasting–low intensity magnetic separation does not effectively remove sulfur in a low valence state, which affects the quality of iron ore concentrate. Thereby, the desulfurization mechanism of the oxidative roasting process was ...
Hace 4 días · ZeRO leverages the aggregate computation and memory resources of data parallelism to reduce the memory and compute requirements of each device (GPU) used for model training. ZeRO reduces the memory consumption of each GPU by partitioning the various model training states (weights, gradients, and optimizer states) across the available ...
Hace 3 días · The increasing size of deep neural networks necessitates effective model compression to improve computational efficiency and reduce their memory footprint. Sparsity and quantization are two prominent compression methods that have individually demonstrated significant reduction in computational and memory footprints while preserving model accuracy. While effective, the interplay between these ...
Hace 1 día · June 3, 2024. Summary: Researchers identified disease-specific reductions in emotional expressivity in Lewy body dementia through deep neural network analysis. This reduced vocal expression is linked to cognitive impairment and brain region atrophy, distinguishing it from Alzheimer’s disease. Their study suggests vocal emotion analysis could ...
Hace 3 días · DRIVEN: deep-learning model for the detection of AHI events. We developed a hybrid deep-learning model named DRIVEN to (1) classify “normal” or AHI events, (apneas, hypopneas type 1, and ...
Hace 4 días · DeepSpeed v0.3 includes new support for pipeline parallelism! Pipeline parallelism improves both the memory and compute efficiency of deep learning training by partitioning the layers of a model into stages that can be processed in parallel.
Hace 4 días · This further aligns with previous studies that found reduced CMRO 2 in deep gray matter nuclei. 5,6 In addition, reduced oxygen consumption in deep cerebral gray matter may play a key role in cognitive function in other neurodegenerative disorders such as Alzheimer’s disease. 52 WM damage is also of note, as the subependymal veins, which drain the periventricular WM regions through medullary ...
