About

Dhiraj Chaudhari is a highly skilled Data Science Enthusiast with a passion for machine learning, deep learning, computer vision, and NLP. He is a storyteller and blogger who is always looking to improve his skills and knowledge in the field of Data Science. Dhiraj is currently working as an Online Class Visual Sentiment Detection Engineer at almabetter, where he developed an app using multiple CNN architectures that detects the sentiment of the online classroom using live video from the webcam and gives feedback to the tutor. He employed essential image preprocessing techniques such as image augmentation, Pixel brightness transformations, etc. He experimented with CNN such as LeNet, AlexNet, VGG16, VGG19, etc. and also used transfer learning to improve model accuracy. The model achieved 67% accuracy on test data. Dhiraj has worked on several projects in the past, including Online Retail Customer Segmentation and Cardiovascular Risk Prediction at almabetter. In these projects, he built several clustering models using K-Means, Hierarchical, and DBSCAN Clustering to identify major customer segments on transactional datasets of an online retail. He performed EDA and RFM modeling by feature engineering to obtain new features such as Recency, Frequency, Monetary, RFM, RFMScores, etc. He also developed a classification model to predict ten-year risk of whether a person will suffer from Coronary Disease by trying Machine Learning classification algorithm. He performed EDA to obtain meaningful insights, did Feature Engineering, experimented with algorithms such as Logistic regression, Naïve Bayes, SVM, Random Forest classifiers, and tuned the hyperparameters to get optimal model performance. Dhiraj has a Bachelor's degree in Civil Engineering from Dr. D. Y. Patil Institute of Management and Research, where he studied from 2017 to 2021. He also has a Higher Secondary degree in Intermediate in Science from Durgabai Raghuvanshi Junior College, Nandurbar, and a Matriculation degree from S. A. M. English Medium High School, Nandurbar. Dhiraj is highly proficient in SQL, ML, Computer Vision, Python, Deep Learning, NLP, Data Scientist, CNN, SVM, test, Research Scientist, Hyperparameter, Neural Networks, Jupyter, Random Forest, Keras, Seaborn, RNN, Scikit, Tensorflow, Pandas, and has 2.36 years of
