Feature-based time-series analysis

23 Sep 2017benfulcher/hctsa

This work presents an introduction to feature-based time-series analysis. The time series as a data type is first described, along with an overview of the interdisciplinary time-series analysis literature.

Multilevel Wavelet Decomposition Network for Interpretable Time Series Analysis

23 Jun 2018AHoke/Multilevel_Wavelet_Decomposition_Network_Pytorch

In light of this, in this paper we propose a wavelet-based neural network structure called multilevel Wavelet Decomposition Network (mWDN) for building frequency-aware deep learning models for time series analysis. mWDN preserves the advantage of multilevel discrete wavelet decomposition in frequency learning while enables the fine-tuning of all parameters under a deep neural network framework.

DLBI: Deep learning guided Bayesian inference for structure reconstruction of super-resolution fluorescence microscopy

20 May 2018lykaust15/DLBI

Super-resolution fluorescence microscopy, with a resolution beyond the diffraction limit of light, has become an indispensable tool to directly visualize biological structures in living cells at a nanometer-scale resolution. Our method combines the strength of deep learning and statistical inference, where deep learning captures the underlying distribution of the fluorophores that are consistent with the observed time-series fluorescent images by exploring local features and correlation along time-axis, and statistical inference further refines the ultrastructure extracted by deep learning and endues physical meaning to the final image.

Recurrent Neural Networks for Multivariate Time Series with Missing Values

6 Jun 2016Han-JD/GRU-D

Multivariate time series data in practical applications, such as health care, geoscience, and biology, are characterized by a variety of missing values. In time series prediction and other related tasks, it has been noted that missing values and their missing patterns are often correlated with the target labels, a.k.a., informative missingness.

Ensemble Sales Forecasting Study in Semiconductor Industry

28 Apr 2017qx0731/ensemble_forecast_methods

Sales forecasting plays a prominent role in business planning and business strategy. Rather than assuming fixed distribution, this non-parametric permutation variable importance analysis provided a general framework across methods to evaluate the variable importance.

catch22: CAnonical Time-series CHaracteristics

29 Jan 2019chlubba/catch22

Capturing the dynamical properties of time series concisely as interpretable feature vectors can enable efficient clustering and classification for time-series applications across science and industry. However, this approach is computationally expensive and involves evaluating many similar features, limiting the widespread adoption of feature-based representations of time series for real-world applications.

Time Series Cluster Kernel for Learning Similarities between Multivariate Time Series with Missing Data

3 Apr 2017FilippoMB/TCK_AE

Similarity-based approaches represent a promising direction for time series analysis. An ensemble learning approach is exploited to ensure robustness to parameters by combining the clustering results of many GMM to form the final kernel.

Dynamic Natural Language Processing with Recurrence Quantification Analysis

19 Mar 2018racdale/crqanlp

This sequence is one that, the author hopes, causes a revisitation of certain thoughts and ideas in others. RQA treats text as a sequential measurement, much like a time series, and can thus be seen as a kind of dynamic natural language processing (NLP).

Model Agnostic Time Series Analysis via Matrix Estimation

25 Feb 2018jehangiramjad/tslib

In effect, this generalizes the widely used Singular Spectrum Analysis (SSA) in time series literature, and allows us to establish a rigorous link between time series analysis and matrix estimation. Another salient feature of our algorithm is that it is model agnostic with respect to both the underlying time dynamics and the noise distribution in the observations.

Time Series Using Exponential Smoothing Cells

9 Jun 2017UW-AMO/TimeSeriesES-Cell

Time series analysis is used to understand and predict dynamic processes, including evolving demands in business, weather, markets, and biological rhythms. We propose a flexible model for time series analysis, using exponential smoothing cells for overlapping time windows.
