AI Customer Support Assistant

• Solo capstone: an end-to-end app that classifies customer complaints by intent and sentiment, clusters them by

topic, and drafts a suggested reply.

• Trained TF-IDF + Logistic Regression for intent classification and MiniLM sentence embeddings + KMeans (5

clusters) for topic clustering on the Bitext customer-support dataset; integrated pretrained sentiment (RoBERTa)

and reply-generation (Qwen2.5) models.
