An open-source library of algorithms to analyse time series in GPU and CPU

Khiva Khiva is an open-source library of efficient algorithms to analyse time series in GPU and CPU. It can be used to extract insights from one or a group of time series. The large number of available methods allow us to understand the nature of each time series. Based on the results of this analysis, users can reduce dimensionality, find out recurrent motifs or discords, understand the seasonality or trend from a given time series, forecasting and detect anomalies. Khiva […]

Improving Unsupervised Image Clustering With Robust Learning

RUC This repo is the PyTorch codes for “Improving Unsupervised Image Clustering With Robust Learning (RUC)” Improving Unsupervised Image Clustering With Robust Learning Sungwon Park, Sungwon Han, Sundong Kim, Danu Kim, Sungkyu Park, Seunghoon Hong, Meeyoung Cha. Highlight RUC is an add-on module to enhance the performance of any off-the-shelf unsupervised learning algorithms. RUC is inspired by robust learning. It first divides clustered data points into clean and noisy set, then refine the clustering results. With RUC, state-of-the-art unsupervised clustering […]

Res2Net: A New Multi-scale Backbone Architecture

Res2Net The official pytorch implemention of the paper “Res2Net: A New Multi-scale Backbone Architecture” Our paper is accepted by IEEE Transactions on Pattern Analysis and Machine Intelligence (TPAMI). We propose a novel building block for CNNs, namely Res2Net, by constructing hierarchical residual-likeconnections within one single residual block. The Res2Net represents multi-scale features at a granular level and increases the rangeof receptive fields for each network layer. The proposed Res2Net block can be plugged into the state-of-the-art backbone CNN models,e.g. , […]
