Predicting The Road Accident Fatality Likelihood

September 23, 2016

The costs of fatalities and injuries due to traffic accidents have a great impact on the society. In recent years, researchers have paid increasing attention to determining factors that significantly affect severity of driver injuries caused by traffic accidents. Applying data mining techniques to model traffic accident data records can help to understand the characteristics of driver's behaviour, roadway condition and weather condition that were causally connected with different injury severity.

What It Took to Score the Top 2% on the Higgs Boson Machine Learning Challenge

August 29, 2016

How do we pit machine learning with physics? Particle physics is a branch of physics that studies the elementary constituents of matter and radiation, and the interactions between them. Modern particle physics research is focused on subatomic particles that use particle accelerator to break the atoms to detect sub-particles (smaller particles than atom). The ATLAS detector at CERN's Large Hadron Collider was built to search the mysterious Higgs Boson responsible for generating the masses. The Higgs Boson is named after particle physicist Peter Higgs, who with other five physicists predicted the existence of such a particle in 1964.

Geospatial and Temporal Data Analysis on the New York City Taxi Trip Data

November 8, 2016

The New York City taxi business is one of the interesting fields for data analysis. The analysis is done on spark and it concentrate on the duration of wait time for the drivers after a successful ride based on location. The data used is from NYC Taxi and Limousine department. The geospatial and temporal data is made to good use in spark and the insights are derived. The final result that is desired is in the form of location and average wait time for next passenger. Hence the data can be used to find the good place to get the customer or lesser wait time in order to get the next customer. The results are pretty assuring and sensible. For example, it is possible to get customers quicker in Manhattan than in Bronx and the output exactly shows that.

Sentiment Analysis Of Yelp User Review Data

August 22, 2016

Social data provides important, real-time insights on consumer opinion – on lifestyle, habits, brands, and preferences. Because these opinions are unsolicited, they provide genuine insight into consumer feelings, and, as such, they should be valued. Yelp provides restaurant details including name, price, rating, address and reviews. The ratings given by the users say how good the restaurant is, but do you really think that the ratings alone is sufficient to give the correct information? No, because people who really hated a restaurant would comment on their experience. The same goes for a the good experience. So, Thus, one would expect that performing sentiment analysis would give give a better insight about judging a into the masses’ opinions of restaurants.

Exploratory Analysis Of New York City Yellow Taxi Data

July 25, 2016

The New York City Taxi & Limousine Commission has released staggeringly detailed historical data covering over 1.1 billion individual taxi trips in the city from January 2009 through June 2015. Taken as a whole, the detailed trip-level data is more than just a vast list of taxi pickup and drop off coordinates. It specifies some other useful information about the number of passengers, pick up times, location and revenue.

I chose this project to understand the dynamics of the yellow taxi industry better. What kind of trips are made in cabs? Where do those trips occur? Does the number of passengers using the taxi follow any pattern? What are the predominant costs and locations of taxi trips, and what are the implications of these findings?

The primary goal of this analysis is to find useful insights to help the yellow taxi cab drivers work smart not work hard.
