Claim 16:
17. A non-transitory computer-readable storage medium storing instructions that cause a processor to:
determine, for a conversion between a video block of a video and a bitstream of the video, that a first intra mode is applied on the video block of the video, wherein a process in the first intra mode includes a matrix vector multiplication operation followed by an upsampling operation to generate prediction samples for the video block of the video; and
perform the conversion based on the prediction samples,
wherein inputs to the upsampling operation include neighboring reference samples of the video block of the video, and
wherein the process in the first intra mode further includes a downsampling operation prior to the matrix vector multiplication operation based on a size of the video block.
