💡 Looking to correlate two 1D arrays (signals, time series, depth series, whatever)? You have lots of options...

Recommended

• dtaidistance
• fastdtw
• tslearn
• dtw-python

Not tried

• pyts
• sequentia — looks interesting
• dtwalign
• dtw-python
• similarity_measures — a bunch of curve distance metrics
• soft-dtw-divergences — soft DTW (differentiable)
• pytorch-softdtw-cuda — soft DTW (differentiable)
• simple-dtw — a gist

Look out of date

• simple-dtw
• soft-dtw — soft DTW (differentiable)
• dtw
• pydtw
• pydtw — apparently different
• pydtw — apparently different again
• pydtw — I mean...

Not recommended

• dxw — very simple algorithm, no bells or whistles, used for teaching about Python packaging.
