Brainhack Global 2018

The goal of the hackathon is to bring together researchers with disparate backgrounds to collaborate on open science projects in neuroimaging. Brainhack Montreal 2018 is part of the Brainhack Global 2018, with simultaneous hackathons running at more than 30 sites across the globe. Participants are encouraged to post project ideas on the website of brainhack Montreal.

Dates: April 26th-27th, 2018

Costs: $30 CAD, includes onsite breakfast and lunch for two days

Location: Centre de Recherche de l’Institut Universitaire de Gériatrie de Montréal (CRIUGM), Montréal, Canada.

UNF special seminar

False Discovery Rate Control Under Rounding of P-Values

Dr Hien Nguyen

Location : CRIUGM (http://www.criugm.qc.ca/en/contact.html), room M6804

Date: December 13th, 13h-14h

The seminar will be presented in English

Dr Hien Nguyen is going to give special seminar of Unité de Neuroimagerie Fonctionnelle (UNF) this coming Wednesday. Dr Nguyen is a Lecturer and Australia Research Council DECRA Research Fellow at La Trobe University in Melbourne Australia. His research currently focuses on the development of Big Data methodologies that are deployable on small-scale computing infrastructures, and deep learning and neural networks for applications in personalised medicine.

Summary:

The mitigation of false positives is an important issue when conducting multiple hypothesis testing. The most popular paradigm for false positives mitigation is via the control of the false discovery rate (FDR). We present a method for FDR control that is applicable in cases where only p-values are available, and when those p-values are potentially equal to zero or one. Our method is based on an empirical-based paradigm where the Probit transformation of the p-values (called the z-scores) are modeled as a two-component mixture of normal distributions. Due to the rounding of the p-values, the usual approach for fitting mixture models cannot be applied. We instead use a binned data technique, which can be proved to consistently estimate the z-score distribution, even when the data are correlated. A simulation study shows that our methodology is competitive with popular alternatives, especially when data are correlated. We demonstrate the applicability of our methodology in practice via a brain imaging study of mice.

UNF 10th Anniversary

It is with great pleasure that we invite you to celebrate the 10th anniversary of the Functional neuroimaging unit (UNF). For this occasion, three internationally renowned researchers will share the latest knowledge in their respective fields.

We will welcome you on Monday, September 22nd, 2014 at 1:00 p.m.at the Amphitheatre National Bank, Hautes Études Commerciales (HEC), 3000 Chemin de la Côte-Sainte-Catherine.

A detailed program will follow shortly.
