Flower Crane

Flower Crane provides some utility functions for working with NumPy arrays.

1. viterbi_decode - find the most likely path along a sequence of observations.
2. compute_thermals
3. apply_time_limit - apply a time limit to decide on base or excited state
4. bearing_change_rate - calculate the change rate of the bearing
5. arg_max_positive_diff - find two indices a, b with b > a which maximize arr[b] - arr[a]
6. find_meeting - find indices in which four dimensional lines are close to each other
7. filter - find and replace outliers in array by comparing with running avg

Develop

First, create a new virtual env and activate it

python -m venv .venv
source .venv/bin/activate

You can install the module locally with

maturin develop

Make sure to update the python type stub in flower_crane.pyi if you change the signature of a function. After you have placed your PyPi API-Token in your .pypirc file, you can publish your module with

maturin publish -r test

or

maturin publish -r pypi

Tests

python -m pytest
cargo test

Benches

To compare the performances of the different implementations, run

maturin build --release
pip install .
python -m py_flower_crane.benchratio
