“We're deployed in Higher education institutions power a lot of Pearson publisher books which are, and a lot of higher ed. Also we actually just launched a product with Houghton Mifflin Harcourt, which has K-twelve. So we're actually in both now.”

“So from a data science perspective, one way to think about this, and it's the way I think about it is that this graph is actually encoding expert prior belief about the structure of knowledge.”

“We've had roughly four million students on the platform in the past year and a half.”

“We have over 200 textbooks that have been described to our system.”

“But at one of our largest partners, we've seen nearly half a great improvement as usage of adaptive assignments increases.”

“There is requisite knowledge that you need, and that's where we're trying to model the content that we're working with, and so I guess it's, what, the question is whether or not you buy that there exists requisite relationships in content, and whether respecti…”

“Something that I personally really value in the people that I hire is something I call data empathy, and it's a skill.”

“Here we, we've done some hierarchical agglomerative clustering to detect the relationships between pieces of content using performance data.”

“We're basically providing a value add for every time a piece of that content gets distributed, and so so we might take a cut of the textbook sale It's a digital textbook or real textbook sale if there's a digital component to it or a cut of the actual of a cla…”
