Changelog for Persistence-2.0
Revision history for Persistence
1.0 -- 2018-05-11
- First version. Released on an unsuspecting world.
1.1 -- 2018-05-27
Added
- Bottleneck distance, a way to compare the topology of different data sets.
- HasseDiagram module, will allow users to deduce topological features of information flow in networks.
- A function for encoding generic graphs as 2D vectors.
Changed
- Improved documentation for all exposed modules.
1.1.3 -- 2018-07-30
Changed
- Fixed a major bug with persistent homology; high dimensional holes were being detected in low dimensional data sets.
- Persistent homology now filters out bar codes of the form (i, Just i), as they say nothing about the topology of the underlying complexes.
1.1.4 -- 2018-09-15
Changed
- Fixed spelling error.
- Persistence now exports the constructors for
Extended a
.
1.1.4.1 -- 2018-09-15
Changed
- Fixed all spelling errors, should actually build now.
1.1.4.2 -- 2018-09-15
Changed
- Fixed non-exhaustive pattern match in
BottleNeckDistance
functions.
2.0 -- To be determined
Changed
-
The module
Persistence
has been renamed toFiltration,
and all modules now exist withinPersistence
. -
Bar codes now take a type as a parameter so that they can not only represent the filtration indices at which features appear but also the scales.
-
Persistent homology functions now take data sets as either vectors or lists.
-
Fixed minor issue with bottleneck distance and removed the unsafe functions.
-
Improved documentation for all exposed modules
-
Extended
type now exports its constructors.
Added
-
Simplex type synonyms for making other type synonyms and signatures more readable.
-
Data structures for filtrations both with and without all vertices having filtration index equal to zero, and persistent homology functions for processing each structure.
-
Persistent homology functions that return Bar codes in terms of scales.
-
Functions for constructing and manipulating persistence landscapes.
