fdacluster 0.3.0 (2023-07-04)
- Added median centroid type;
- Median and mean centroid types are now defined on the union of individual grids;
- Simplified
caps class to avoid storing objects multiple times under different names;
- Added vignette on initialization strategies for k-means;
- Added article on use case about the Berkeley growth study;
- Added article on supported input formats.
fdacluster 0.2.2 (2023-05-25)
- Make sure one can use fdacluster with namespace notation.
- Make sure not to use fda or funData before checking it is available.
fdacluster 0.2.1 (2023-05-19)
- Add DBSCAN clustering;
- Fix C++ compiler issues that errored when accessing empty vectors.
fdacluster 0.2.0 (2023-05-18)
- Add hierarchical clustering;
- Enforce
n_clusters in output via linear programming (LP) using the
lpSolve package;
- New
caps class
for storing results from functional Clustering with Amplitude and
Phase Separation in a consistent way;
- Add tools for comparing clustering results (
mcaps objects, autoplot and
plot specialized method implementations);
- Add seeding strategies for kmeans (via hierarchical clustering or k-means++ or
k-means++ with exhaustive search of the first center or exhaustive search of all
the centers);
- Add within-cluster domain auto-extension via mean imputation;
- Add possibility to cluster according to phase variability instead of amplitude
variability.
- Renaming of functions: to perform k-means with alignment, now use
fdakmeans(),
to perform HAC with alignment, now use
fdahclust().
