Glow: Generative Flow with Invertible 1x1 Convolutions

openai/glow NeurIPS 2018

Flow-based generative models (Dinh et al., 2014) are conceptually attractive due to tractability of the exact log-likelihood, tractability of exact latent-variable inference, and parallelizability of both training and synthesis.

XGBoost: A Scalable Tree Boosting System

dmlc/xgboost 9 Mar 2016

In this paper, we describe a scalable end-to-end tree boosting system called XGBoost, which is used widely by data scientists to achieve state-of-the-art results on many machine learning challenges.

LSTM-based Encoder-Decoder for Multi-sensor Anomaly Detection

chickenbestlover/RNN-Time-series-Anomaly-Detection 1 Jul 2016

Mechanical devices such as engines, vehicles, aircrafts, etc., are typically instrumented with numerous sensors to capture the behavior and health of the machine.

Deep and Confident Prediction for Time Series at Uber

PawaritL/BayesianLSTM 6 Sep 2017

Reliable uncertainty estimation for time series prediction is critical in many fields, including physics, biology, and manufacturing.

A Deep Neural Network for Unsupervised Anomaly Detection and Diagnosis in Multivariate Time Series Data

KONI-SZ/MSCRED 20 Nov 2018

Subsequently, given the signature matrices, a convolutional encoder is employed to encode the inter-sensor (time series) correlations and an attention based Convolutional Long-Short Term Memory (ConvLSTM) network is developed to capture the temporal patterns.

TadGAN: Time Series Anomaly Detection Using Generative Adversarial Networks

signals-dev/Orion 16 Sep 2020

However, detecting anomalies in time series data is particularly challenging due to the vague definition of anomalies and said data's frequent lack of labels and highly complex temporal correlations.

PyPOTS: A Python Toolbox for Data Mining on Partially-Observed Time Series

WenjieDu/PyPOTS 30 May 2023

PyPOTS is an open-source Python library dedicated to data mining and analysis on multivariate partially-observed time series, i. e. incomplete time series with missing values, A. K. A.

DeepAnT: A Deep Learning Approach for Unsupervised Anomaly Detection in Time Series

swlee23/deep-learning-time-series-anomaly-detection 19 Dec 2018

In contrast to the anomaly detection methods where anomalies are learned, DeepAnT uses unlabeled data to capture and learn the data distribution that is used to forecast the normal behavior of a time series.

Time-Series Anomaly Detection Service at Microsoft

yoshinaga0106/spectral-residual 10 Jun 2019

At Microsoft, we develop a time-series anomaly detection service which helps customers to monitor the time-series continuously and alert for potential incidents on time.

Anomaly Transformer: Time Series Anomaly Detection with Association Discrepancy

thuml/Anomaly-Transformer ICLR 2022

Unsupervised detection of anomaly points in time series is a challenging problem, which requires the model to derive a distinguishable criterion.
