Class to compute the Hill transformation of media.
Inherits From: AdstockHillTransformer
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.

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.

It takes two main tensors as input: `ec` and `slope`, both with optional batch dimensions matching each other. The `forward` method applies the Hill function to a `media` tensor, which may include batch, geo, time, and media channel dimensions. This method returns a tensor with the same geo, time, and media channel dimensions as the input, representing the Hill-transformed media.\n"],null,[]]
