gtda.diagrams
: Persistence diagrams¶
The module gtda.diagrams
implements transformers to preprocess
persistence diagrams, extract features from them, or compute pairwise distances
between diagrams.
Preprocessing¶
Replaces all homology dimensions in persistence diagrams with |
|
|
Linear scaling of persistence diagrams. |
|
Filtering of persistence diagrams. |
Distances¶
|
Distances between pairs of persistence diagrams. |
Representations¶
|
Persistence landscapes of persistence diagrams. |
|
Betti curves of persistence diagrams. |
|
Convolution of persistence diagrams with a Gaussian kernel. |
|
Persistence images of persistence diagrams. |
|
Power-weighted silhouettes of persistence diagrams. |
Features¶
|
Amplitudes of persistence diagrams. |
|
Persistence entropies of persistence diagrams. |
|
Number of off-diagonal points in persistence diagrams, per homology dimension. |
|
Coefficients of complex polynomials whose roots are obtained from points in persistence diagrams. |
