An open source framework for configuring, building, deploying and maintaining deep learning models in Python. As Instacart has grown, we’ve learned a few things the hard way. We’re open sourcing Lore, a framework to make machine learning approachable for Engineers and maintainable for Machine Learning Researchers. A common feeling in Machine Learning: Uhhh, this single sheet of paper does not tell me how this is supposed to work… Common Problems Performance bottlenecks are easy to hit when you’re writing bespoke code at high levels like Python or SQL. Code Complexity grows because valuable models are the result of many iterative changes, making individual insights harder to maintain and communicate as the code evolves in an unstructured way. Repeatability suffers as data and library dependencies are constantly in flux. Information overload makes it easy to miss newly available low hanging fruit when trying to keep up with the latest papers, packages, features,....
