Large-Scale Beamforming for Massive MIMO via Randomized Sketching [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2019
Massive MIMO system yields significant improvements in spectral and energy efficiency for future wireless communication systems. The regularized zero-forcing (RZF) beamforming is able to provide good performance with the capability of achieving numerical

On Sketching Quadratic Forms [PDF]

open access: yesInformation Technology Convergence and Services, 2015
We undertake a systematic study of sketching a quadratic form: given an n x n matrix A, create a succinct sketch sk(A) which can produce (without further access to A) a multiplicative (1+ε)-approximation to xT A x for any desired query x ∈ Rn.

Using Fuzzy Hybrid Features to Classify Strokes in Interactive Sketches

open access: yesAdvances in Mechanical Engineering, 2013
A novel method is presented based on fuzzy hybrid-based features to classify strokes into 2D line drawings, and a human computer interactive system is developed for assisting designers in conceptual design stage. Fuzzy classifiers are built based on some

sourmash: a library for MinHash sketching of DNA

open access: yesJournal of Open Source Software, 2016
sourmash is a toolbox for creating, comparing, and manipulating MinHash sketches of genomic data. MinHash sketches provide a lightweight way to store “signatures” of large DNA or RNA sequence collections, and then compare or search them using a Jaccard ...

Creating and Using Minimizer Sketches in Computational Genomics

open access: yesJ. Comput. Biol., 2023
Processing large data sets has become an essential part of computational genomics. Greatly increased availability of sequence data from multiple sources has fueled breakthroughs in genomics and related fields but has led to computational challenges ...

Large-scale sequence comparisons with sourmash

open access: yesbioRxiv, 2019
The sourmash software package uses MinHash-based sketching to create “signatures”, compressed representations of DNA, RNA, and protein sequences, that can be stored, searched, explored, and taxonomically annotated.

ESKEMAP: exact sketch-based read mapping

open access: yesAlgorithms for Molecular Biology
Background Given a sequencing read, the broad goal of read mapping is to find the location(s) in the reference genome that have a “similar sequence”. Traditionally, “similar sequence” was defined as having a high alignment score and read mappers were ...
