PROJECTS
• PySpark: Music Artist Recommendation on Yahoo! Music Data:
A PySpark application based on ALS algorithm was developed to recommend a user music artists. The data cleaning process involved
scaling down the ratings to a range of 0 to 5 and removing the outliers that skew the modeling. The data was split in the ratio 0.6:0.2:0.2
for training, validation and testing, with the validation and testing sets containing only the user and artist ids. An ALS based model was
built and the performance was evaluated on RMSE metric. A new user was hardcoded to the original dataset with random ratings to
eight artists. A model was trained on this updated dataset and scores for other artist’s were predicted. Finally, 5 artists with the best
predicted ratings were suggested to the user.
• MapReduce Application to Analyze On-time Performance of US Domestic Flights:
A Hadoop Map Reduce application to report maximum departure delay for each originating airport, average arrival delay by flight
number and minimum arrival delay for all origin-destination airport combinations. Individual mappers and reducers were developed
for each task. The intermediate data from the mapper was sorted and sent as input to the reducer.
• Yahoo! Answers Best Answer Validation:
The project validated the accuracy of best answer selection procedure. Used NLTK to preprocess the corpus and deployed machine
learning algorithms using Sklearn module to model the validation engine. Some of the analysis were estimation of the answer length
(best answers in most cases are written by combining the best parts of the answers posted earlier), estimation of cosine-similarity,
estimation of jaccard similarity and topic modeling(using Gensim) to cluster similar answers.
• Twitter Text Analysis - US Presidential Candidates:
The project involved Sentiment Analysis of the tweet corpus to understand the sentimental influence of each presidential candidate.
We studied the tweets based on the states, to understand the candidates influence with respect to the states. We also created a word
cloud to display the top 50 words that appeared in the overall tweets to give a perspective of how people react to politics on social
media.
