Instead of looping over individual series, it uses NumPy's array operations to process all series at once, trading a single loop for parallel computation. The package exposes a KalmanFilter class that accepts standard Kalman parameters (state transition, process noise, observation model, observation noise) and provides smooth() and predict() methods to filter and forecast data.\n\nThe main use case is when you have many independent time series that need the same Kalman filter applied\u2014for example, smoothing sensor readings from 1000 independent devices, or filtering multiple stock prices with the same model. In such cases, vectorization can yield substantial speedups. The package depends only on NumPy and installs as a pure Python wheel, making it lightweight. Maintenance is dormant (last release 972 days ago), but the code is marked Production/Stable and carries no known vulnerabilities.","worth_installing":"Yes, if you need to apply Kalman filters to many independent time series in parallel. The vectorized design and low install friction make it a good fit for batch filtering tasks. However, maintenance is dormant\u2014no updates in 972 days\u2014so evaluate whether you need ongoing support or can work with a stable but no-longer-maintained codebase. No known vulnerabilities and MIT licensing present no barriers."},"id":"simdkalman","links":{"html":"https://skillfed.io/packages/simdkalman","md":"https://skillfed.io/packages/simdkalman.md","pypi":"https://pypi.org/project/simdkalman/"},"maintenance":{"status":"dormant"},"meta":{"latest_release":"2023-12-16","license_spdx":null,"license_treatment":"permissive","name":"simdkalman","python_support":"unspecified","summary":"Kalman filters vectorized as Single Instruction, Multiple Data"},"popularity":{"monthly_downloads":89369,"position":13664,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.0.4"}
