The present disclosure provides a video generation method, an apparatus, a device, a storage medium, and a program product, and the method includes: in response to a first instruction triggered for an input text, generating first video editing data based on the input text, in which the first video editing data includes a first video clip and an audio clip, a first target video clip among the first video clip is a vacant clip; displaying the first video clip and the audio clip on a video editing track of a video editor; in response to triggering a second instruction for the target video clip on the video editor, filling the first target video clip with a target video to obtain second video editing data; generating a first video based on the second video editing data.

A method for principal component analysis includes receiving a principal component analysis (PCA) request from a user requesting data processing hardware to perform PCA on a dataset, the dataset including a plurality of input features. The method further includes training a PCA model on the plurality of input features of the dataset. The method includes determining, using the trained PCA model, one or more principal components of the dataset. The method also includes generating, based on the plurality of input features and the one or more principal components, one or more embedded features of the dataset. The method includes returning the one or more embedded features to the user.
