Method apply()

Applies the class on a single persistence diagram and outputs the result.

Usage

PreprocessingStep$apply(diag)

Arguments

diag

A 2-column tibble::tibble specifying a persistence diagram.

Returns

A 2-column tibble::tibble storing the preprocessed persistence diagram.

---

Method fit()

Fits the class on a sample of persistence diagrams.

Usage

PreprocessingStep$fit(X, y = NULL)

Arguments

X

A list of 2-column tibble::tibbles specifying a sample of persistence diagrams.

y

An integer vector specifying persistence diagram labels (unused for now).

Returns

The class itself invisibly.

---

Method transform()

Applies the class on a sample of persistence diagrams.

Usage

PreprocessingStep$transform(X)

Arguments

X

A list of 2-column tibble::tibbles specifying a sample of persistence diagrams.

Returns

A list of 2-column tibble::tibbles storing the preprocessed persistence diagrams.

---

Method fit_transform()

Applies sequentially the ⁠$fit()⁠ and ⁠$transform()⁠ methods on a sample of persistence diagrams in a more efficient way than calling them directly.

Usage

PreprocessingStep$fit_transform(X, y = NULL)

Arguments

X

A list of 2-column tibble::tibbles specifying a sample of persistence diagrams.

y

An integer vector specifying persistence diagram labels (unused for now).

Returns

A list of 2-column tibble::tibbles storing the preprocessed persistence diagrams.

---

Method clone()

The objects of this class are cloneable with this method.

Usage

PreprocessingStep$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
