Moirai-MoE: Empowering Time Series Foundation Models with Sparse Mixture of Experts
Moirai-MoE: Empowering Time Series Foundation Models with Sparse Mixture of Experts

MOIRAI-MOE emphasizes that feature specific specialization in timeseries foundation model cannot help generalize input signals and is an hindrance in zero-shot prompting. MOIRAI-MOE underscores that processing mut be done at token level inside the transformer modules with a mixture of experts (FFNs) and a gating algorithm to decide which togen goes to which expert.

Chronos-2: From Univariate to Universal Forecasting
Chronos-2: From Univariate to Universal Forecasting

Chronos 2 is the first ever multivariate time-series forecasting foundation model. It leverages time attention (across time axis) and group attention (across different signals within group) to predict quantiles instead of point estimates.

UniCast: A Unified Multimodal Prompting Framework for Time Series Forecasting
UniCast: A Unified Multimodal Prompting Framework for Time Series Forecasting

Unicast is a timeseries forecasting foundation model. It leverages multi-modal data (visual and textual information) from a timeseries through embedding generators and aligns the output of the embedders to forecasting task using parameter efficient soft prompting.

A General Search-Based Framework for Generating Textual Counterfactual
A General Search-Based Framework for Generating Textual Counterfactual

This paper is a search based but fast counterfactual generation method for textual data. It proposes three operators to conduct the search in an anytime algorithm. Therefore, the more time it gets the better qulaity countefactual it delivers.

Towards Unifying Evaluation of Counterfactual Explanations: Leveraging Large Language Models for Human-Centric Assessments
Towards Unifying Evaluation of Counterfactual Explanations: Leveraging Large Language Models for Human-Centric Assessments

Since evaluation of counterfactual explanations is a difficult task, his paper tries to automate the process by fine-tuning large language models (LLMs) on human ratings for counterfactuals.
