The Comcast Labs DC Research Team invents the technological foundations for the Xfinity experiences of the future. Besides long-term research efforts in NLP, computer vision, and machine learning (with a focus on deep learning), we support the Comcast Technology & Products organization through innovations and technical expertise in these product domains:

Voice: Communicate with your TV, mobile device or home using natural language.

Deep Metadata: Understand content at a deeper level to label and categorize the moments and segments of interest with computer vision and machine learning.

Knowledge Representations:  Organize and structure information using novel representations that allow for more human-like queries and insights.

Personalization for Search & Recommendations: Improve the quality of search, recommendations, predictive analytics, and more using advanced machine learning techniques.

Data Science:  Improve customer service experiences or detect outages before they happen with advanced machine learning models.
