Closed

Description

@superichmann

Is your feature request related to a problem? Please describe.
No

Describe the solution you'd like
Add native support for learning feature embeddings from time-series data using self-supervised learning.

The learned representation should be usable as input to existing ML.NET trainers and support standard ML.NET model persistence and pipelines.

Describe alternatives you've considered
None

    @superichmann could you show some real use-case for this feature? We currently don't support self-supervised time-series representation and we would need to see high demand for such investment.
