T4transport 0.1.7

• Removed dependence on CVXR package.

T4transport 0.1.6

• API references restructured.
• Added a number of functions for histograms, including distance, barycenter, interpolation, and median.
• Added img2measure() to extract a discrete measure from a gray-scale image matrix.
• New family of routines for Gromov-Wasserstein geometry, gwdist() and gwbary(), added.

T4transport 0.1.5

• Replaced lpSolve package’s EMD solver with Nicolas Bonneel’s highly-optimized C library.
• Added functions for Procrustes-Wasserstein geometry: pwdist() and pwbary().

T4transport 0.1.4

• rbarygd() for a Riemannian gradient descent to compute the free-support barycenter is added.

T4transport 0.1.3

• Changed the structure of the package.
• Applied the log-sum-exp trick for numerical stability to the entropic regularization solver.
• rbary23L() added for simple free-support Wasserstein barycenter computation.
• Two ad hoc median routines for images and histograms are removed.

T4transport 0.1.2

• gaussmed1d() and gaussmedpd() now fully respects the product manifold perspective.
• gwdist() added for Sliced-Wasserstein distance computation.

T4transport 0.1.1

• Support for special types of data. See the reference for more details.

T4transport 0.1.0
