We are looking for talents to join us on this exciting journey! Responsibilities
Conduct cutting-edge research in retrieval and recommendation algorithms and multi-modality modeling with focus on developing machine learning (ML) models for understanding short-form videos using various modalities, including video frames, text descriptions, and background audio that are fundamental to moderation, searching, and recommendation for short-form videos.
Work on Data-driven training (with hyperparameters search) of the neural network models.
Perform offline evaluation (pseudo-A/B test) of the trained models using real-world short-form videos and document each model's detailed specification, training procedure, and evaluation result.
Communicate with the internal content moderation team on the technical needs (specifications and resources) to develop software for neural network models.
Review and analyze latest literature on the state-of-the-art neural network models for video understanding.
Publish research papers that benefit the academic community.
Qualifications Must have a Master’s degree or foreign equivalent degree in Computer Science, Engineering (any), Information Technology, Machine Learning, Data Science, Mathematics, Statistics, or a related quantitative field, and 2 years of related work and/or research experience.
