Accomplishments

  • Credit Card Fraud Detection using Hybrid Ensemble Mo
  • Task: Classify the fraudulent and legitimate transaction using Hybrid Ensemble Model
  • Use Case: The model is trained on European credit card fraud dataset and credit card stimulation dataset
  • Preprocessed using oversampling and covert highly imbalanced dataset into balanced dataset
  • Hybrid Ensemble is trained on balanced dataset to predict the classification output by combining random forest and Adaboost
  • Restaurant Review Prediction using Machine learning and NLP
  • Task: Prediction and classification of restaurant reviews either “Good” or “bad” using Word Embedded and Machine Learning algorithm
  • Use Case: Help researchers better understand to choose the better restaurant
  • Preprocessed and covert text data into numerical by wordcount technique
  • Machine learning algorithm include Logistic regression, Support vector machine, decision Tree
  • Comparison all algorithm and choose better accuracy result and then predict the good and bad restaurant
