kanalweise

Kanalweise is a German adverb used in technical contexts to indicate that an operation is applied independently to each channel of a multi-channel data structure, such as an image, a spectrogram, or a feature map. The term combines Kanal (channel) with the suffix -weise, roughly translating to “per channel” or “by channel.” It is commonly found in discussions of image processing, signal processing, and machine learning.

Typical usages include kanalweise Normalisierung, kanalweise Aktivierung, or kanalweise Skalierung, where for every channel the respective statistic or parameter is computed and applied separately. This is often contrasted with approaches that operate globally across channels or rely on cross-channel interactions.

In practice, kanalweise processing means that each channel is treated as its own small data unit, preserving channel-specific characteristics while applying the operation. In neural networks, kanalweise operations are common for per-channel affine transformations and for normalization schemes that apply parameters independently to each channel.

Notes: The term is primarily used in German-language technical writing. Its meaning depends on context, particularly which dimension is designated as the channel (for example color channels in images versus feature channels in networks). Care should be taken to distinguish kanalweise processing from methods that aggregate information across channels.
