DREAM CHALLENGES

The DREAM (Dialogue for Reverse
Engineering Assessment and Methods) project was founded in 2006 to
assess model predictions and pathway inference algorithms in systems
biology. Today DREAM aims to foster collaboration amongst
researchers, to evaluate computational biology methodologies, and to
multiply the impact of data by making it available to a vast
community. DREAM achieves its goals through the organization of
Scientific Challenges and conferences.
The DREAM Challenges
are open problems presented to the systems biology community of
potential solvers. Participants submit their predictions, which are
evaluated and scored, and eventually discussed in the annual DREAM
conference. Eventually data, predictions, gold standards and source
code are openly available. In the past 7 years, DREAM has run 28
successful Challenges, enabled the publication of over 60 DREAM
Challenge-related papers, and aggregated a "crowd" of thousands of
"DREAMERs."
In 2013, Sage Bionetworks (www.sagebase.org) and
DREAM partnered to co-lead a new generation of Challenges that
leverage collaborative data hosting and analysis tools available on
Synapse (www.synapse.org) such as real-time leaderboards and shared
project spaces.
Announcing the DREAM9 Challenges
On June
2, 2014, we launched the DREAM9 "Challenge season" which consists of
three new Challenges described below. These challenges will be
discussed at the RECOMB/ISCB Systems and Regulatory Genomics/DREAM
Conference to be held in San Diego, CA November 10-14, 2014.
1. Alzheimer's Disease Big Data DREAM Challenge #1 The goal of
this Challenge is to identify accurate predictive Alzheimer's
disease biomarkers that can be used by the scientific, industry and
regulatory communities to improve Alzheimer's diagnosis and
treatment. Participants will work with genetics data, clinical data
and imaging data to create predictive models of cognitive scores,
predict discordance between cognitive ability and amyloid load
and/or predict diagnostic groups.
2. The DREAM AML Outcome
Prediction Challenge The goal of this Challenge is to develop the
best predictive models of clinical outcome in AML. Participants are
given the clinical correlates, genetics and cyto-genetics data and
the expression level of 231 proteins probed by RPPA analysis of a
cohort of AML patients. Challenge participants are asked to predict
which AML patients will be primarily resistant to therapy and which
patients will have complete remission as well as to predict
remission duration and overall survival.
3. The Broad-DREAM Gene
Essentiality Prediction Challenge The goal of this Challenge is to
infer genes that are essential to cancer cell viability using gene
expression and/or gene copy number features. This Challenge, which
will leverage the data from the NCI funded project Achilles, is a
natural progression of the NCI-DREAM7 Drug Sensitivity predictions
challenge.
For more details about how to register to
participate in these Challenges, a description of these and other
ongoing Challenges, the incentives for participation (including
publication opportunities and podium presentation at conference) and
the collaborators and sponsors that enabled the Challenges please go

solution of these important Translational Systems Biology
challenges. Contacts: Thea Norman (thea.norman@sagebase.org) and
