Foundation Model for Personalized Recommendation

Netflix Tech

However, as we expanded our set of personalization algorithms to meet increasing business needs, maintenance of the recommender system became quite costly. Incremental training : Foundation models are trained on extensive datasets, including every members history of plays and actions, making frequent retraining impractical. Zhai et al.,

Detecting Speech and Music in Audio Content

Netflix Tech

Practical use cases for speech & music activity Audio dataset preparation Speech & music activity is an important preprocessing step to prepare corpora for training. Nevertheless, noisy labels allow us to increase the scale of the dataset with minimal manual efforts and potentially generalize better across different types of content.
