Recent Releases of PySensors

PySensors - pre-JOSS release

This release introduces significant changes and features to the API which include

Reconstruction

Introduces regularized reconstruction, based on Bayesian MAP state estimate and pointwise standard deviation of the error std. Renames previous reconstruction method as unregularized reconstruction.

Optimizers

Adds the following optimizers - GQR (General QR) - Provides access to the pivoting procedure for spatially constrained sensor placement. - TPGR (Two Point GReedy) - Handles sensor undersampling and oversampling, and provides pointwise sensor interaction landscapes.

Additional Features

  • Adds three spatial constraint types - region, predetermined, and distance.
  • Adds support for different shapes of spatial constraints - circle, cylinder, line, parabola, ellipse, polygon and UserDefinedConstraints
  • Adds custom basis support (e.g., DMD basis).
  • Adds uncertainty heatmaps showing noise propagation in sensor measurements to state reconstruction. # Example Notebooks Introduces these example notebooks
  • Constrained sensing for simulation of a fuel rod - demonstrates the use of spatial constraints.
  • Two-point greedy (TPGR) sensor placement on sea surface temperature data - demonstrates uncertainty quantification and landscapes.
  • Reconstruction comparison on Olivetti Dataset - compares unregularized vs regularized reconstruction using TPGR optimizer, and compares the QR and TPGR optimizers with unregularized and regularized reconstruction.

Updates all existing notebooks to comply with the new functionalities.

PySensors - Add warning

This release merely adds a warning when the number of sensors exceeds the number of samples and the CCQR optimizer is used. In this case sensors may be selected from constrained regions. See #14.

PySensors - Refactoring of PySensors

In addition to fixing minor bugs and adding content to the examples, the primary change in this release is the renaming of the SensorSelector class to SSPOR (Sparse Sensor Placement Optimization for Reconstruction). See #8 for more details.

PySensors - Initial version

PySensors initial version

This is an initial version of PySensors, which will soon by superseded by v1.0.0. It includes most of the basic functionality that will be included in v1.0.0, but is not fully polished.

Features

  • SensorSelector class for sparse sensor selection for reconstruction
  • SSPOC class for sparse sensor selection for classification
  • Basis classes
    • Identity
    • SVD
    • RandomProjection
  • Jupyter notebooks showing how to use various PySensors features
