MLFLHMDA: predicting human microbe-disease association based on multi-view latent feature learning
Published 2024-02-01“…Specifically, we compute Gaussian interaction profile kernel similarity between diseases and microbes based on the known microbe-disease associations from the Human Microbe-Disease Association Database and perform a preprocessing step on the resulting microbe-disease association matrix, namely, weighting K nearest known neighbors (WKNKN) to reduce the sparsity of the microbe-disease association matrix. …”

Forward-Looking Super-Resolution Imaging for Sea-Surface Target with Multi-Prior Bayesian Method
Published 2021-12-01“…Secondly, we fuse the total variation (TV) prior and Laplace prior, and propose a multi-prior to model the contour information and sparsity of the target. Third, we introduce the latent variable to simplify the logarithm likelihood function. …”

Supersparse linear integer models for optimized medical scoring systems
Published 2016“…SLIM scoring systems are built by using an integer programming problem that directly encodes measures of accuracy (the 0–1 loss) and sparsity (the ℓ[subscript 0]-seminorm) while restricting coefficients to coprime integers. …”

Post-Selection Inference for Generalized Linear Models With Many Controls
Published 2018“…These methods allow to estimate α[subscript 0] at the root-n rate when the total number p of other regressors, called controls, potentially exceeds the sample size n using sparsity assumptions. The sparsity assumption means that there is a subset of s < n controls, which suffices to accurately approximate the nuisance part of the regression function. …”

Eyeriss v2: A Flexible Accelerator for Emerging Deep Neural Networks on Mobile Devices
Published 2021“…These endeavors aim to reduce the DNN model size and improve the hardware processing efficiency and have resulted in DNNs that are much more compact in their structures and/or have high data sparsity. These compact or sparse models are different from the traditional large ones in that there is much more variation in their layer shapes and sizes and often require specialized hardware to exploit sparsity for performance improvement. …”
