The Future is Tiny Graphs! [1] In the style of "Scalability! At What COST?" I've started a side-project bringing succinct data structures (rank/select [2], elias-fano coding) and m…

Think: resnet+imagenet but for videos: https://github.com/moabitcoin/ig65m-pytorch We ported the r(2+1)d model (from CVPR 2018, see https://arxiv.org/abs/1711.11248) and the weight…

We are running it internally on our aerial imagery from the Mapbox Maps API. The zoom level even there depends on the feature you want to extract, for example z18 seems to work wel…

We haven't released pre-trained models yet. Mostly for two reasons: 1/ The PyTorch checkpoints depend on the specific Python model class. Even if you refactor only e.g. a MaxPool l…

I haven no experience with TensorFlow.js. That said, using the RoboSat ONNX model exporter (rs export) you should be able to go from a trained PyTorch model to a portable ONNX prot…

Daniel from Mapbox here. Happy to answer questions or talk through design decisions. Interested to hear your feedback. We are mostly focusing on making the process accessible to a …

Sentinel 2 data could be interesting for you. With its high refresh rate it can be used for change detection. The multi-band data is especially useful for adding more input channel…

Here is how I build architecture optimized TensorFlow 1.4 binaries for specific AWS instance types: https://gist.github.com/daniel-j-h/b410dd21d4949a54c83d0c386... The build script…

Check out metric trees such as the BK-Tree, VP-Tree or GNATs. They allow for fast nearest neighbor searches, for example querying all items in your database with Hamming Distance h…

Absolutely. The following two new checks are impressive and should be on by default. New misc-move-forwarding-reference check Warns when std::move is applied to a forwarding refere…

Here's an interesting anecdote for -ffast-math: the Kahan summation algorithm [1] can be used to reduce numerical errors in sums. Now have a look at the codegen [2] without and wit…

The sliding shortest path paper is really interesting. I'm thinking about what this scenario means for road networks and if it makes sense there at all (not considering the algorit…
