Hi, I am Tasha!


Welcome to my Portfolio
My aim is to solve challenging problems and help the society with the power of data, statistics, and programming.

All projects:

Project II: Sentiment Analysis of ChatGPT tweets

In this project, I executed the sentiment analysis of tweets on CHAT GPT. I cleaned and pre-process the tweets (using bag-of-words model) and determined the sentiment of each tweet using two different methods. I created 4 different classification models [Logistical Regression, Multinomial Naive Bayes, Support Vector Machine (SVM), and Random Forest] and compared them to determine the best performing model.

Project III: Stock price prediction - Time series analysis

In this project, I compared stock prices of FAANG companies with 7 years of data. I did a detailed time-series analysis of the stocks of AMAZON. I used ARIMA, SARIMA, and Prophet models and fit them with the time series. I found the forecast of the stock price of Amazon for 1 year in future.

Project IV: Sentiment analysis of customer reviews

In this project, I performed sentiment analysis of reviews by customers of an E-commerce women's clothing brand. After cleaning and pre-processing the reviews, I used two vectorisation approaches: bag-of-words and TF-IDF to do word vectorisation. I trained the reviews on 4 classification models to determine the best performing model.

Project V: Survival prediction for Titanic passengers

In this project, I used different machine learning models to predict the survival of passengers based on various features in the dataset. I performed One-hot encoding, feature removal, feature scaling on the features and trained four machine learning models on the data-set: Logistic regression, Kernal SVM, Decision tree, Random forest. I then identify the best performing model using Grid search and K-fold cross validation and make the prediction for test data.
