Irregular Time Series

3 papers with code · Time Series

Modeling real-world multidimensional time series can be particularly challenging when these are sporadically observed (i.e., sampling is irregular both in time and across dimensions)—such as in the case of clinical patient data.

Arm order recognition in multi-armed bandit problem with laser chaos time series

26 May 2020

By exploiting ultrafast and irregular time series generated by lasers with delayed feedback, we have previously demonstrated a scalable algorithm to solve multi-armed bandit (MAB) problems utilizing the time-division multiplexing of laser chaos time series.

Path Imputation Strategies for Signature Models of Irregular Time Series

25 May 2020

The signature transform is a 'universal nonlinearity' on the space of continuous vector-valued paths, and has received attention for use in machine learning on time series.

Modeling Continuous Stochastic Processes with Dynamic Normalizing Flows

24 Feb 2020

Normalizing flows transform a simple base distribution into a complex target distribution and have proved to be powerful models for data generation and density estimation.

Multi-resolution Networks For Flexible Irregular Time Series Modeling (Multi-FIT)

30 Apr 2019

Vertical FIT (FIT-V) is a variant of FIT which also models the relationship between different temporal signals while creating the informative dense representations for the signal.

Temporal-Clustering Invariance in Irregular Healthcare Time Series

27 Apr 2019

We postulate that fine temporal detail, e. g., whether a series of blood tests are completed at once or in rapid succession should not alter predictions based on this data.
