Hello NuPIC, Recently at Numenta, we've been working on using the CLA for anomaly detection in GPS tracking. As part of this effort, we've created an encoder that can convert a GPS position to an SDR. It has the following desired properties:
1. Positions spatially close together have overlapping bits in the encoding. 2. When moving at low speeds, resolution of movement is more fine, and when moving at high speeds, resolution of movement is more coarse. Thus, when moving at higher speeds, bigger movements still retain overlapping bits. 3. It works anywhere in the world; in fact, it works for an infinitely large space of any number of dimensions. We just incorporated the encoder into NuPIC so everyone can start experimenting with it [1]. We're still working on use cases, good datasets, and ironing out bugs. So let me know if you have any issues or suggestions! [1] https://github.com/numenta/nupic/pull/1005 Bon voyage, Chetan
