About

TensorHouse is a collection of reference Jupyter notebooks and demo AI/ML applications for enterprise use cases: marketing, pricing, supply chain, smart manufacturing, and more. The goal of the project is to provide a toolkit for rapid readiness assessment, exploratory data analysis, and prototyping of various modeling approaches for typical enterprise AI/ML/data science projects.

TensorHouse contains the following resources:

• a well-documented repository of reference notebooks and demo applications (prototypes),
• a collection of readiness assessment and requirement gathering questionnaires for typical enterprise AI/ML projects,
• a manually curated list of important papers in enterprise AI,
• a manually curated list of public datasets related to enterprise use cases.

The project focuses on models, techniques, and datasets that were originally developed either by industry practitioners or by academic researchers who worked in collaboration with leading companies in technology, retail, manufacturing, and other sectors. In other words, TensorHouse focuses mainly on industry-proven methods and models rather than on theoretical research.

List of Prototypes and Templates

The artifacts listed in this section can help to rapidly evaluate different solution approaches and build prototypes using your datasets. Some artifacts can help with doing exploratory data analysis, e.g. evaluating the strength of causal effects in your data and determining whether these data is feasible for solving a certain use case or not.
