PAGA: graph abstraction reconciles clustering with trajectory inference through a topology preserving map of single cells

Abstract Single-cell RNA-seq quantifies biological heterogeneity across both discrete cell types and continuous cell transitions.Partition-based graph abstraction (PAGA) Lentils provides an interpretable graph-like map of the arising data manifold, based on estimating connectivity of manifold partitions (https://github.com/theislab/paga).PAGA maps

Averaging and sampling for magnetic-observatory hourly data

A time and frequency-domain analysis is made of the effects of averaging and sampling methods used for constructing magnetic-observatory hourly data values.Using 1-min data as a proxy for continuous, geomagnetic variation, we construct synthetic hourly values of two standard types: instantaneous "spot" measurements and simple 1-h "boxcar" averages.

Optimizing Dynamic Mode Decomposition for Video Denoising via Plug-and-Play Alternating Direction Method of Multipliers

Dynamic mode decomposition (DMD) is a powerful tool for separating the background and foreground in videos.This algorithm decomposes a video into dynamic modes, called DMD modes, to facilitate the extraction of the near-zero mode, which represents Stashes the stationary background.Simultaneously, it captures the evolving motion in the remaining mod
