v11.2.0

Release adds bisection search to invert the bijection in block neural autoregressive flows (BlockAutoregressiveNetwork).

Possible but unlikely breaking change:

• BlockAutoregressiveNetwork inverse methods will no longer raise a NotImplementedError, which could be a breaking change e.g. if a user relies on exception handling.

What's Changed

• Add bisection inverter by @danielward27 in #122
• Adapt bisection interval bug fix by @danielward27 in #123
• Handle exact solution in bisection search by @danielward27 in #125

Full Changelog: v11.1.0...v11.2.0

v11.1.0

Should be no breaking changes from v11.0.0. Adds LogNormal and Laplace.

What's Changed

• Update readme by @danielward27 in #119
• Add LogNormal by @danielward27 in #120
• add Laplace by @danielward27 in #121

Full Changelog: v11.0.0...v11.1.0

v11.0.0

The most important breaking changes (in importance order) are:

1. Renaming of flows

• All the flows have moved from being classes (with standard PascalCase naming) to functions with the standard snake_case naming.
• Reason for change: None of the flows implemented any methods or extended the base class AbstractTransformed other than forwarding basic information about the bijection, so the use of classes was not needed. Instead, flows now are functions that return a Transformed distribution.

2. Key word only arguments

• A lot of functions and classes now make use of key word only arguments to ensure more readable code (e.g. as TriangularAffine(loc, arr, lower=True) is much clearer than TriangularAffine(loc, arr, True).
• This may introduce errors along the lines of TypeError: function takes at most ... arguments (... given), but this should be straightforward to fix by converting to using key word arguments where required.

3. Abstract{Distribution/Bijection}

• Bijection has been renamed to AbstractBijection
• Distribution has been renamed to AbstractDistribution

4. Custom bijections

• Custom bijection implementations no longer need to manually validate input shapes, as the methods are automatically wrapped during an __init_subclass__ method in AbstractBijection. The bijection method _argcheck_and_cast has been removed as it is no longer needed.
