%description
Efficiently implementing two complementary methodologies for discovering
motifs in functional data: ProbKMA and FunBIalign. Cremona and Chiaromonte
(2023) "Probabilistic K-means with Local Alignment for Clustering and
Motif Discovery in Functional Data" <doi:10.1080/10618600.2022.2156522> is
a probabilistic K-means algorithm that leverages local alignment and fuzzy
clustering to identify recurring patterns (candidate functional motifs)
across and within curves, allowing different portions of the same curve to
belong to different clusters. It includes a family of distances and a
normalization to discover various motif types and learns motif lengths in
a data-driven manner. It can also be used for local clustering of
misaligned data. Di Iorio, Cremona, and Chiaromonte (2023) "funBIalign: A
Hierarchical Algorithm for Functional Motif Discovery Based on Mean
Squared Residue Scores" <doi:10.48550/arXiv.2306.04254> applies
hierarchical agglomerative clustering with a functional generalization of
the Mean Squared Residue Score to identify motifs of a specified length in
curves. This deterministic method includes a small set of user-tunable
parameters. Both algorithms are suitable for single curves or sets of
curves. The package also includes a flexible function to simulate
functional data with embedded motifs, allowing users to generate benchmark
datasets for validating and comparing motif discovery methods.
