The Laboratory for Interactive Human-Computer Analytics works in a variety of application domains, including medical informatics, journalism, data and bioengineering.

LIHCA: A Software Platform for Human-in-the-Loop Analytics Systems

This software platform makes it easy to build interactive machine learning tools.  You can follow the simple instructions to install the open-source server-side software and then you are ready to connect from your JavaScript front-end with our API.  LIHCA provides a JavaScript object that lets you run machine learning algorithms on the server using python, with several scikitlearn implementations wrapped plus extras like metric learning.  The library also makes dealing with sessions, data and logging user interactions and model updates simple.

Journalism in the Age of Wikileaks

Working with we are tackling the problem of developing stories from massive piles of text.  Using interactive machine learning we help journalists and other users to discover threads of their stories in document collections.

IRIS – Integrated Radiological Image Search

ModelSpace – Visualizing the Trails of Data Models in Visual Analytics

Taking advantage of how human-in-the-loop analytics systems create machine learning models from user inputs, we use vector representations of these models to chart each user’s path through the space of models.  Read about it in ModelSpace at MLUIVA.
