Output column in GeoParquet table with statistics (mean, count, min/max) of an input band #185

Closed weiji14 closed 4 months ago

weiji14 commented 6 months ago

Idea that came up during our regular meetings, on generalizing the cloud-cover percentage patch-level info (i.e. extending #168) to other bands/channels, so that someone could apply other filters based on certain columns with some statistics (mean, count, min/max, percentage, etc) derived from the input images. This would enable pre-filtering based on attributes when performing Similiarity Search.

Example:

embedding cloud_cover_percentage mean_elevation max_temperature bbox
[0.1, 0.4, ... x768] 20% 100m 25°C POLYGON(...)
[0.2, 0.5, ... x768] 30% 300m 20°C POLYGON(...)
[0.3, 0.6, ... x768] 40% 500m 15°C POLYGON(...)

This would involve generalizing the inference part of the code somehow, specifically the predict_step function here:

https://github.com/Clay-foundation/model/blob/0145e55bcf6bd3e9b19f5c07819a1398b6a22c35/src/model_clay.py#L855-L921

Some changes might also need to happen on the DataLoader side, so that these statistical measures are passed through. Parking this as an idea for now.

Good idea, but not sure if this is still relevant. We won't always have a way to assess cloud cover in this predict step. @srmsoumya is this code still operational?

srmsoumya commented 4 months ago

We don't have a predict_step in v1, we should add a script instead, that takes maybe a tile as input & creates embedding for chip size defined by the user. This can be scalable & we could add AWS batch scripts for these.

ok in that case closing here, let's revisit when doing prediction scripts
