Feature Refactor

Major changes:

• Add new c/fortran extensions for features
• Refactor core features to allow for n-dimensional array inputs

Version 0.5.1

Changes

• [Gait] Change CWT scale calculation to better match paper

Version 0.5.0

Major Changes:

• [Gait] gait processing now always downsamples when required. Downsampling used to be only for classification, now it is for the whole process
• [Gait] added back number of valid full gait cycles to output metrics

Version 0.4.1

Changes

• [Gait] Changed how gait predictions were broadcast to samples, and gait bout start/end creation at native frequency
• [Gait] Add option to save gait predictions to a file

Version 0.4.0

Major Changes:

• Add a GT3X reader for Actigraph files
• [Gait] Change classification downsampling to linear from cubic, and use NumPy.interp for huge memory savings
• [Gait] Allow no downsampling for gait classification if sampling frequency is within +- 1.5% of goal frequencies
• [Gait] Change sampling period computation to use entire time series to minimize effect of poor spacings

Minor Changes:

• Add testing for edge cases for several gait metrics
• Incorporate logging and logging tests
• Harmonic ratio needs a minimum of 11 harmonics

Version 0.3.0

Major Changes:

• Added logging in places where user input/code can't be changed.
• Added logging messages when starting processing, if the user is using logging

Gait changes:

• move vertical axis computation to a per-bout level to deal with potential sensor placement changes
• add a check and minimum of 10 harmonics necessary to compute the Harmonic Ratio
• removed unnecessary keys from the gait results dictionary (IC, FC, FC opp foot, b valid cycle)
• gait results returned now only include the cycles which were valid

Version 0.2.0

Major Changes:

• pipeline infrastructure
• gait is all tests
• numerous bug fixes

Version 0.1.0

First release, with functionality in the following sub-modules:

• sit2stand
• features
• read (for reading in data from geneactiv and axivity data files)
