· Sentiment Analysis on Customer Reviews : Developed a Deep Learning based
Sentiment classification model (Flair Library) using customer reviews data. The model was trained on 235,310 reviews with “Positive”, “Neutral” and “Negative”
as the classification labels. An accuracy of around 92% was achieved on the test set.
· Emotion Analysis on Customer Reviews : Developed a Deep Learning based
Emotion Classification model (Flair Library) using customer reviews data. The model was trained on 235,310 reviews with “Joy”, “Trust”, “Surprise”, “Anger”,
“Fear” and “Sadness” as the Emotion classes. An accuracy of 86% was achieved on the test set.
· Topic Extraction from Customer Reviews : Used Non-Negative Matrix
Factorization (NMF) technique to extract relevant Topics from user reviews data.
Coherence Scoring was used to decide on the optimal number of topics that can be extracted from the given set of reviews.
· Creating Automated Insight Statements : Using the Topic and Sentiment Model results, create automated Insight Statements, so that report generation becomes faster.
· Exploratory Data Analysis on Customer Contacts Data : Received Customer
Contacts data from client Belair which had around 17 Million records. Performed
EDA on the different available features including NULL value analysis and faulty records detection. There were 11 attributes present in the dataset including age,
contact-number, email, traveller details etc.

· Tracking Car Route Deviation : Created an algorithm for Detecting Deviation in
Car Routes to ensure lesser chances of accidents and assign Route Familiarity
Scores to the drivers based on their past trip details.
Score means lesser chance of getting lost and ensures safer driving habits.
· Detecting chances of accidents based on Car Video Analytics : Used SSD
MobileNet object detection algorithm along with CSRT Tracking algorithm to detect and track objects close to the vehicle in question and generate alert accordingly.
