Recently I came across a NIPS2015 paper from Vartak et al that describes a system (APIs + visual frontend) to support the iterative model building process. The problem they are addressing is common one in most machine learning settings – building multiple models (different type) using various features and identifying one or more optimal models to […]
Surveying the Opinion of Chemists
As part of a project I was wondering about reports of surveys that collected chemists assessments of differnt things. More specifically, I wasn’t looking for crowd-sourcing efforts for data curation (such as the in the Spectral Game) or data collection. Rather, I was interested in reports where somebody asked a group of chemists what they […]
Post-doc (Molecular Informatics) Opening at NCATS
I have a post-doc opening in the Informatics group at NCATS, to work on computational aspects of high throughput combination screening – topics will include predicting drug combination response, visualizing large combination screens (> 5000 combinations) and so on. The NCATS combination screening platform thas tested more than 65,000 compound combinations (in checkerboard style which […]

In support of its charter, the Trust has created a unique Grant Program and is now inviting the submission of grant applications for 2015. Purpose of the Grants The Grant […]
Ridit Analysis
While preparing material for an R workshop I ran at NCATS I was pointed to the topic of ridit analysis. Since I hadn’t heard of this technique before I decided to look into it and investigate how R could be used for such an analysis (and yes, there is a package for it). Why ridit […]
