Example for predicting success/failure and multiclass ordinal problems

1

Hi Thomas, would you entertain a documentation PR on this? I often use LIME for 2-class success/failure problems and sometimes multiclass ordinal. Yesterday I had some UX questions from a...

mapview fails silently for sf object mixing polygon/multipolygon, but works for sp with same mix

2

The issue title basically covers what's happening: when I plot an sf object with mixed polygon/multipolygon types, mapview fails silently (generates a completely blank map, no error/warning). I can convert...

option for makevalid => TRUE when converting geojson back to geography in BQ

2

Hi, very excited to use these tools -- thanks for making them publicly available. I'm running into frequent circumstances where a buffer operation returns an invalid polygon, which causes the...

Distance-weighted random sampling of non-neighbor negatives

2

Not a fully-baked feature request, just a directional hunch. I've found the conclusions from this paper [Sampling Matters in Deep Embedding Learning](https://arxiv.org/abs/1706.07567) pretty intuitive -- (1) the method for choosing...

Partial composites with a subset of tiles from a full tile_grid?

3

I'm a few days into heavy use of `slippymath` and really enjoying it -- thank you! FWIW, I'm using it to rapidly construct training sets for some image analysis prototyping...

Feature request: convert UInt64 S2 IDs (as string) to S2 cell IDs

2

A hopefully-small feature request. I'm seeing data in the wild that uses UInt64 representations of S2 cell IDs. An example here is the [global rooftop dataset in Source Cooperative](https://beta.source.coop/repositories/vida/google-microsoft-open-buildings/description/) where...
