Expand description

Result from a single GMM fit with fixed K.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§cluster: Vec<usize>

Hard cluster assignments (length n)

§membership: FdMatrix

Posterior membership probabilities (n x K)

§means: Vec<Vec<f64>>

Component means (K x d)

§covariances: Vec<Vec<f64>>

Component covariances: for Full, each is d×d flattened; for Diagonal, each is length d

§weights: Vec<f64>

Mixing proportions (length K)

§log_likelihood: f64

Log-likelihood at convergence

§bic: f64

BIC value

§icl: f64

ICL value (BIC penalized by entropy)

§iterations: usize

Number of EM iterations

§converged: bool

Whether EM converged

§k: usize

Number of clusters

§d: usize

Feature dimension (basis coefficients + covariates)
