Yaradesi Sai Kumar
Professional Summary
Machine Learning Engineer Intern with 1+ years of experience applying machine learning and deep learning to biomedical signal and tabular datasets. Experienced in data preprocessing, EDA, model development (classical and transformer-based), and reproducible experimentation using Python, scikit-learn and PyTorch. Seeking internship/entry-level roles to apply signal-processing and deep-learning skills to deliver robust, production-ready models.
Technical Skills
Work Experience
- Led data ingestion and end-to-end preprocessing for multiple client tabular datasets using pandas and NumPy, implementing robust handling for missing values, categorical encoding, and outlier treatment to prepare data for modeling.
- Performed exploratory data analysis and visualizations with matplotlib and seaborn to identify predictive features and inform feature-engineering decisions for model pipelines.
- Developed and evaluated supervised models (logistic regression, random forest) using scikit-learn; designed cross-validation workflows to compare model performance and recommend best-fit algorithms for stakeholders.
- Implemented hyperparameter tuning with GridSearchCV and scikit-learn pipelines to improve validation generalization and reduce overfitting across candidate models.
- Packaged trained models as serialized artifacts (joblib/pickle) and produced reproducible Jupyter notebooks documenting preprocessing, training, and evaluation steps for handover to engineering teams.
- Collaborated with a small team using Git for version control, produced concise technical reports and presentations summarizing model findings and data-driven recommendations for non-technical stakeholders.
Projects
- Designed and implemented a transformer-based AttentionNet to learn spectral representations from EEG signals for brain-state classification under anesthesia.
- Executed signal preprocessing and spectral feature extraction using SciPy and NumPy, creating inputs tailored for transformer attention blocks.
- Trained and validated the model in PyTorch, implemented attention mechanisms to focus on salient spectral bands, and analyzed model behavior via visualization of attention scores and loss curves.
