- Fine-tuned pre-trained LLMs (GPT-3.5-turbo-0613, HuggingFace BERT-base) on product review datasets to perform sentiment analysis and keyword extraction; integrated transfer learning techniques and optimized hyperparameters using AdamW; improved sentiment analysis accuracy by 82% using cross-entropy loss and keyword extraction F1-score by 38% - Designed a 3-layer LSTM architecture incorporating ReLU activations, dropout regularization, and batch normalization to process user behavioral data (e.g., views, clicks, purchases) and survey features; implemented embedding layers to encode categorical inputs and utilized a time-distributed dense layer for temporal feature learning. - Built a product ranking algorithm using an ensembled multi-classifier approach (Random Forest, Gradient Boosting, XGBoost) on 48 product parameters; optimized hyperparameters with Hyperopt, resulting in a 9% increase in purchase rate and a 38% rise in click-through rate. Deployed the pipeline using TensorFlow, PyTorch and BentoML, incorporating ONNX for cross-platform compatibility and real-time inference scalability.
