“It was my great pleasure to be Prakatheeswari's manager during her internship. She came with a strong background in data science and was able to contribute immediately to develop a web app using Plotly Dash over a short period of time. She's very meticulous and was able to prepare a very large dataset from disparate sources for use in the web app. I was very impressed by her problem solving skills and how much ownership she took in her project. She interacted well with her peers and also different team members from other functions. At the end of her internship, she gave an excellent presentation to the senior leadership team, which really impressed them and set the foundation for further collaborations across different functions. Really great accomplishments and beyond my expectations for an intern. 👍”

Comparative Study of Time Series and ARIMA Model on Stock Data
-
Presented paper in National Conference on Research Advances in Science and Technology at CSI College of Engineering, Ooty. Finding the best model to predict stock data
Projects
-
Emotion Classification using transfer learning:
-
• Created a machine learning model utilizing Transfer Learning (MobileNet) to categorize the emotion in an image. Implemented the model in python and achieved an accuracy of 94%.
• Utilized FER dataset from Kaggle to train the model, comprised of 7 emotion categories. By deploying this model, it is possible to recognize human emotions in real-time. -
Application Management System
-
To Build a Machine Learning Model, which will help to shortlist the potential candidates, based on certain criteria. The model is deployed in the cloud.
Tools used: Python,
Techniques Used: Logistic Regression in Machine Learning and Flask for deploying model in the cloud. -
Analysis and Prediction of Cancer Rates Before and After Sterlite
-
Presented paper in National Conference on Machine Learning and Artificial Intelligence conducted by Indian. IIM Bangalore and CIT Coimbatore. Performed regression analysis to infer whether the cancer rates have been influenced or not.
-
Credit Score Classification
-
Performed Extensive Data cleaning and analyzed the patterns on credit score dataset using Clustering, Regression,
Classification and Visualization (Seaborn) techniques to establish three interesting findings.
Trained a Decision Tree model, Random Forest model and K-NN classification to predict the credit score and performed a
comparative study using AUC score as the metric. -
House Price Prediction using Ensemble models
-
- Conducted exploratory data analysis to identify patterns and trends in data
- Performed feature engineering to extract meaningful information from features
- Built machine learning models using algorithms such as linear regression, random forest, xg boost, lasso, ridge, and gradient boosting
- Experimented with ensemble models such as stacking and blending to improve performance
- Evaluated each model's performance using metrics such as mean squared error and root mean squared…- Conducted exploratory data analysis to identify patterns and trends in data

- Evaluated each model's performance using metrics such as mean squared error and root mean squared error
- Achieved a final rank of 243 in the competition after multiple iterations and rounds of model training and evaluation. -
Image Classification Using Convolutional Neural Networks (CNN)
-
Implemented a CNN classification model using TensorFlow and Keras to predict image classes with an accuracy of 94%.
Optimized the model's performance through data preprocessing techniques such as scaling, data splitting, and augmentation -
Sales Forecasting Analysis
-
• Developed a predictive model to find out the sales of a product at a particular store using various model and conducted a
comparative study.
• The main objective is to compare the Linear regression model, Decision Tree Model, Random Forest and Extra Tree
Regressor leveraging CV Score as the metric.
• Built an interactive dashboard in PowerBI to gain deeper insight about the data. -
Twitter Sentiment Analysis
-
Implemented Sentiment Analysis on twitter data using Natural Language processing. Applied count vectorizer technique to extract features for processing the model. Built a logistic regression model to classify the sentiment of tweet.
• Retrieved live tweets using twitter API. Performed Exploratory data analysis on data to understand the features, for anomaly detection and assigned the target value by calculating the positive and negative word count. -
