Professional Experience

RETAI L SOLUT IONS I nc.

CA, USA

Data Science Intern, Predictive Analytics Team

M ay’14-Aug’14

• Improved the out of stock Alert metric by 12 15% based on POS data using k means clustering, robust linear regression.

Classified the Retail Stores on the basis of weather and demographic data for better promotion strategies and on shelve

management.

• Developed new models to incorporate promotional effects on sales with adaptive EMA, different sales mean and clusterings

• Upgraded the Alert Filtering Mechanism using d Tree, Logistic regression and SVM and achieved 72 % overall accuracy

WÄRTSILÄ F I N LAND OY.

Vaasa, Finland

Summer Internee, Noise and Vibration Department

M ay’12-July’12

• Improved clamping and piping structure to make pressure system robust against mechanical vibrations using FEA & FFT

• Resulted in 80% run-time failure reduction. E stablished Gear Hammering as cause of piping system

failure leading to suspensions

V I L LANOVA UN I VERSI TY

PA, USA

Summer Research Intern, Autonomous Systems Lab

M ay’11-July’11

• Established Hypoplastic Left Heart Syndrome disorder as a potential cause of Periventricular-

Leukomalacia in new born babies

• Modeled human circulatory system and simulated Newtonian blood f low, suggested a new way of

surgery to increase the blood f low

Project Work

Semantic understanding of rough sketches by human (Computer Vision)

Sept’14-Present

• Identified the root cause of in-accuracy for identifying semantic information about rough sketches

d rawn by people

• Working on perceptual-hash database to fasten the comparison for a new sketch with whole database.

T his helps in recognition of an object from various alignment in space

Demographic and geographic disparities in the total cost per inpatient hospitalization ( HCUP-

US) Nov’13-Apr’14

• Analyzed 2-level (County & DRG) healthcare data and found socio-economic & geo-spatial disparities

i n total cost of hospitalization

• Developed a mixed effect predictive cost model to project the cost of t reatment which was not recorded

i n respective counties for CA, FL & NC. Tried to balance the bias of unique number of t reatments in

county

• Found 341% geographical variation in hospital costs per inpatient for general t reatments while

controlling variables: length of stay etc.

Customer behavior prediction of power usage in geographical & chronological domain

(Verdeeco, I nc.) A pr’14

• Developed f lexible pricing plans on no-gain basis to balance demand geographically to prevent the

failure of the smart grid.

• Fetched the t ime-series power usage data using API. Applied Hierarchical clustering to identify

outliers and k-means to cluster & identify the relationships between power usage w.r.t. time and

location.

D ata M ining from YouTube and I M Db database

Feb’14

• Automated the fetching of YouTube videos related personality information from I MDb database using

Regular Expressions in Python with an improved approach of searching by choosing nouns in keyword

• Suggested the similar videos from YouTube by directly fetching the data from the source code of search

result page
