The animation shows how Kepler detects planets. As the
planet passes between the host star and the spacecraft,
the observed star brightness decreases slightly, signaling
the potential detection of a planet.
Kepler looked at over 150,000 stars continuously for four
years in the constellations Cygnus and Lyra, seeking to
record the slight periodic brightness changes in stars that
could reveal the presence of planets.
Kepler detects planets by taking a photometric measurement
of the stars in its field of view every 30 minutes. A planet
transit will show as a small periodic dip in the “light curve” of
a star over time.
Kepler Data
Goal: Detect planet(s) currently missed by the
Kepler Team’s automatic search programs --
likely “super-Earths” with long periods

Quasar Spectra Pair Method
The identification of 2175 bump is based on Mgii
absorber catalog with limitation:
• We can only identify the 2175 bump in the redshift
range from 0.7 to 2.5.
• The method is based on Mg II absorber catalog. If the
Mg ii absorber catalog is not complete, the 2175
bump sample may not be complete.

Bipolar Disorder & Challenge Objectives
• Bipolar disorder is a brain disease that causes
unusual mood shifts
• Estimated 51% of affected population go
untreated in a given year
• Detection not straightforward - symptoms and
test metrics not too dissimilar from other brain
disease
• Recent studies indicate heritability and
genetic factors as causes opening new area of
detection using genome data.
• CAGI challenge given to predict the bipolar
disorder using exomes .
• Exome sequencing data of 1000 samples with
500 for training and 500 for prediction
challengeImage source http://www.nimh.nih.gov/health/statistics/prevalence/
bipolar-disorder-among-adults.shtml

28. Scalable Software Systems Laboratory
Data Pre-Processing
n Extracted genotype information from the exomes
n The genotypes were 0/0,0/1,1/1 and ./.
n One-hot-encoding transformation on the genotypes i.e 0/0
encoded as 0100, 0/1 encoded as 0010,etc.
n One hot encoding treats all categorical variables equidistant
