Vibration Data Analysis and Condition Monitoring

Role

Data Scientist

Description

Condition monitoring by analysis of Vibration data for determining the health of a device. Time waveform, Spectrum
Analysis, Fourier Transform are some of the techniques used here. Designing rules based on statistical considerations
such as movement of orders, persona changes, etc. Setting up the architecture for scaling of Fault Detection,
interpretation of faults, etc. Further suggested and developed framework for predictive models to determine the
probability of failure of a component.

Natural Language Processing – Financial Modelling

Role

Data Scientist

Description

Prediction of alpha based on sentiment and stock price movement data. Processing of financial articles and
determining sentiments attached to it, using NLTK library (sentient and vader). External sentiment data was
correlated with Stock movement data and subsequently, machine learning models were built. These models were
made accessible using Flask in Python. Also a search mechanism was developed using TF-IDF models and cosine
similarity score. Given a stock and sentiment polarity, most relevant articles related to stocks are found. Models
created were operationalized with help of Flask library available in python.

Data Science for an automotive client

Description

Worked on data science initiatives to bring down costs related to repair and maintenance. I have set
up the data pipeline which reads data from various tables and creates a single dataset which helps in building
machine learning models to determine probability of component failure given a symptom and service model name.
This helps in maintaining appropriate stock at various warehouses.
Second use case is to find the reasons of repeated visits. Repeated visits are source of revenue impact as warranty is
breached when an engine comes for repair within a month of earlier visit. This is a data discovery exercise where I am
writing R Script to generate dataset which contains reason, symptoms related to a repeated visit and find probable
causes.
