meridian.model.adstock_hill.HillTransformer

Class to compute the Hill transformation of media.

meridian.model.adstock_hill.HillTransformer(
    ec: meridian.backend.Tensor,
    slope: meridian.backend.Tensor
)

Args
`ec`	Tensor with dimensions `[..., n_media_channels]`. Batch dimensions `(...)` are optional, but if batch dimensions are included, they must match the batch dimensions of `ec`.
`slope`	Tensor with dimensions `[..., n_media_channels]`. Batch dimensions `(...)` are optional, but if batch dimensions are included, they must match the batch dimensions of `slope`.

Methods

forward(
    media: meridian.backend.Tensor
) -> meridian.backend.Tensor

Computes the Hill transformation of a given media tensor.

Calculates results for the Hill function, which accounts for the diminishing returns of media effects.

Args
`media`	Tensor with dimensions `[..., n_geos, n_media_times, n_media_channels]`. Batch dimensions `(...)` are optional, but if batch dimensions are included, they must match the batch dimensions of `slope` and `ec`. Media is not required to have batch dimensions even if `slope` and `ec` contain batch dimensions.

Returns
Tensor with dimensions `[..., n_geos, n_media_times, n_media_channels]` representing Hill-transformed media.
