• Geocollider: generic functionality for finding potential matches between two placename datasets. Example: find the matching place in GeoNames for a Pleiades place
• Aimed at providing generic functionality previously implemented in one-off scripts
  • Pleiades+ (GeoNames): https://github.com/ryanfb/pleiades-plus
  • Pleiades/TGN: https://github.com/ryanfb/pleiades-tgn
• Geocollider is a Ruby gem: https://github.com/isawnyu/geocollider

Synthesize a MIDI file to WAV from the command line using FluidSynth:

fluidsynth -F output.wav soundfont.sf2 input.mid

Some popular SoundFonts: GeneralUser GS, Fluid R3 GM, some others.

DeepBach uses the Python music21 library for MIDI parsing, but only supports monophonic MIDI (it throws 'Chord' object has no attribute 'pitch' if you give it a polyphonic MIDI file). The patch here lets it use polyphonic MIDI by arbitrarily using the first pitch in a chord.

In this tutorial, I'll give a quick way to filter Pleiades places to those contained within a modern country's borders.

Install GDAL with brew install gdal (on a Mac) or download GDAL binaries for your platform.

Download a modern country's shapefile (for this example, Bulgaria) from GADM: http://www.gadm.org/country

Download the latest Pleiades KMZ data dump. Unzip to KML with unzip pleiades-latest.kmz.

Use the top-level administrative boundary for Bulgaria to clip the resulting tmp/doc.kml file and save the result as GeoJSON:

About

These are my public, unorganized notes on stumbling blocks I've run across setting up DeepMask / SharpMask for training: https://github.com/facebookresearch/deepmask

NNProject_DeepMask

An alternative (non-Facebook, Python instead of Torch) open-source implementation of DeepMask was previously available here: https://github.com/abbypa/NNProject_DeepMask

Before the Facebook code was released, I started some work on Dockerizing this implementation which may also help others use it: https://github.com/ryanfb/NNProject_DeepMask/blob/docker_experimental/Dockerfile
