Here are some ways you’ll make an impact:

• Using exploratory data analysis, unsupervised and supervised modeling, statistics, and related techniques to understand and predict the value of the entire range of user-generated and AI-generated content on Course Hero and associated domains - from documents like essays and notes, to conversational utterances like questions and study assistance inquiries.
• Detecting the lowest value content too, which is often spam and/or fraud.
• Build models that prescribe an optimal strategy of publishing content, given the above noted prediction scores.
• Investigate other forms of malicious abuse of the platform including, payment fraud, and marketplace fraud.
