Introduction

Today, we are excited to share with you how Comcast, one of the largest multi-service operators in the U.S., is utilizing machine learning to enhance various aspects of its business. In this article, we will discuss four different use cases where machine learning has been implemented at Comcast and the challenges faced in operationalizing these models.

Comcast: A Brief Overview

Comcast is a renowned corporation that offers high-speed internet, an Emmy-winning video platform (X1), IP telephony, home security and automation services, Universal Studios theme parks, and several media properties. With tens of millions of customers and hundreds of millions of devices on its network, Comcast operates in the Big Data space, making machine learning a crucial tool for solving complex problems at Scale.

Use Case 1: Driving Features within the X1 Platform

Live TV viewing remains the dominant form of video consumption, with up to fifty percent of leisure time spent watching live TV. Comcast's video research team is leveraging machine learning to drive features within the X1 platform, such as search for content, personalized recommendations, voice control features, and deep metadata. By using an ensemble of gradient boosted decision trees, Comcast accurately predicts the popularity of TV shows and movies 24 hours in advance, allowing them to showcase trending content on the X1 platform ahead of its airing.

Use Case 2: Improving Customer Care

Comcast faces the challenge of avoidable truck rolls, where a technician is scheduled to resolve a Customer Service issue that could have been easily fixed remotely. To tackle this problem, Comcast's data science team aims to build a predictive model to prevent unnecessary truck rolls. By leveraging H2O and performing extensive feature engineering, they have developed a reasonably accurate model. However, the team encountered challenges such as data scaling and information leakage, which required the adoption of balanced class algorithms and sub-sampling methods to improve model performance and mitigate overfitting.

Use Case 3: Enhancing Customer Experience

Comcast recognizes the importance of improving customer experience to better understand customer needs and prioritize hardware deployment in crucial regions. Currently, service group utilization is measured as an indicator of customer experience. However, Comcast aims to create a better customer experience metric by integrating service computerization data, video streaming quality data, and network data. Through clustering algorithms, they Seek to classify customers into different buckets based on their experience. This approach enables targeted hardware deployment and actionable insights for improving customer experience.

Use Case 4: Building Resilient and Reliable Products

Comcast's vision is to build more resilient and reliable products by integrating machine learning into its systems. By leveraging intelligent online systems, Comcast aims to automate error resolution and reduce the effort required from both customers and employees. This involves real-time data streams, intelligent rules engines, and the deployment of machine learning models to suggest automated fixes in response to potential system errors. However, a key challenge lies in operationalizing these models and integrating them with existing products, ensuring seamless execution and validation.

Conclusion

Comcast's implementation of machine learning across various use cases demonstrates the power of data-driven decision-making in enhancing customer experience, improving operational efficiency, and driving innovation. While challenges exist in scaling and operationalizing models, Comcast continues to invest in cutting-edge technologies like H2O and Spark to overcome these hurdles. With a commitment to building resilient and reliable products, Comcast is well-positioned to leverage the potential of machine learning in the ever-evolving media and telecommunications industry.
