Key-Frames-Extraction-from-Video

December 9, 2019 – December 14, 2020

Using Color Histogram, SVD and Dynamic Clustering Method obtained Key-Frames from a video. This analysis can be used to identify frames which make a shot. The code is well documented.

Sentiment-Analysis-of-Twitter-Data-using-Pre-trained-Vector-and-Neural-Network

December 8, 2019 – January 7, 2021

The challenge is to obtain Ten-fold cross validation auc score more than 0.803. After basic cleaning and spelling correction i used pre-trained Glove vector to find 200D representation for words in tweet which are there in Glove Vector words dictionary. Then i summed the (matching) vectors to obtain 200D feacture vector for each tweet. Atlast, i fitted a neural network with 1 hidden layer. I obtained 0.81 10-Fold cross validation auc score.

After basic cleaning and spelling correction i used pre-trained Glove vector to find 200D representation for words in tweet which are there in Glove Vector words dictionary. Then i summed the (matching) vectors to obtain 200D feacture vector for each tweet. Atlast, i fitted Random Forest Algorithm. I obtained 0.793 10-Fold cross validation auc score.

Sentiment-Analysis-of-Twitter-Data-using-DTM-SVD-and-ML

December 8, 2019 – January 7, 2021

The challenge is to obtain Ten-fold cross validation auc score more than 0.803. The approach i have taken is to first clean the tweets, spelling correction, lemmatization, stop words removal, creating document term matrix (since all frequent words already have been removed) , dimensionality reduction and then finally fitting ML Algorithm. These approaches are pretty naive. With this approach i could reach to 0.775 10-fold cross validation auc score.

ML-Model-to-identify-Churning-Customer-

December 8, 2019 – December 8, 2019

The challenge is to obtain Ten-fold Cross Validation AUC Score above 0.893, given telecom data with 'Churn' as target variable.

Creating-a-Credit-Scoring-Model-to-obtain-the-probability-of-default

December 8, 2019 – December 8, 2019

We have baseline and loan performance information for approximately 6000 loans. The target variable (BAD) is a binary variable indicating whether an applicant eventually defaulted or was seriously delinquent. We have 12 recorded variables for each applicant. Given these information we want to obtain a predictive model which outputs 'probability of default'. Our model should be interpretable and statistically sound so that we can give the reasons for rejections.
