About the Team:
With deep domain expertise, advanced technical capabilities, and a proven track record of
successful collaborations, the AI Enablement & Machine Learning team at CNN is
accelerating our digital transformation through strategic applications of machine learning
and AI technologies. Our current products include popular, related and personalized
content recommendations, contextual ad targeting, and site search-serving millions of
CNN users via CNN web and mobile apps. Within the next quarter, we will be launching
summarization and classification features with chat to follow early next year.
We have a variety of specializations and collaborate closely, enhancing our platform and
adding to the suite of machine learning features running on it.
• Machine learning engineers (MLEs) build models and features
• Data engineers fulfill the availability and latency requirements provided by MLEs
• Some software engineers partner with MLEs to operationalize and expose models
and features
• Other software engineers focus on our ML platform and tooling, including A/B
testing
Here are some of the key challenges the team will tackle in next couple of quarters:
• Content Summaries: Support testing and adoption of various types of content
summaries from multiple domains, which can be leveraged in consumer
experiences along with embedding generation and classification.
• Two-Tower Experimentation: Explore options for incorporating additional user
context in our personalized recommendations model such as geolocation, time of
day and time of year
• All Access Search: Partner with teams across CNN to design and build a roadmap
for CNN streaming content search.
• Bandit Foundation: Enhance data access and begin experimenting with bandits for
online ranking of recommendations
• Optimize Site Performance: Dynamically deliver personalized content alongside
cached assets, improving load times and enhancing user experience with features
like page-level deduplication
