Classification specification helper

Usage

dkge_classification_spec(
  targets,
  method = c("lda", "logit"),
  folds = NULL,
  lambda = NULL,
  metric = c("accuracy", "logloss"),
  mode = c("auto", "cell", "cell_cross", "delta"),
  ...
)

Arguments

targets: Target specification accepted by [dkge_classify()].
method: Classifier backend ("lda" or "logit").
folds: Optional fold specification.
lambda: Optional ridge parameter.
metric: Classification metrics to report.
mode: Decoding mode passed to [dkge_classify()]: "auto" selects automatically, "cell" uses per-cell embeddings, "cell_cross" uses cross-validated per-cell embeddings, and "delta" uses pairwise deltas.
...: Additional fields stored on the spec (e.g., `n_perm`, `scope`).

Value

Object with class `dkge_classification_spec`.

Examples

cls <- dkge_classification_spec(targets = ~ condition, method = "lda")
