🤖 Patient Emotion Classifier

Advanced AI-Powered Emotion Recognition for Healthcare Dialogues

Part of the Blended AI+X Initiative — Bridging Artificial Intelligence and Healthcare

🔬 Overview

We are thrilled to introduce Patient Emotion Classifier, a state-of-the-art NLP model engineered to understand emotional nuances in patient-doctor conversations.

This model represents our commitment to advancing AI for Healthcare (AI+X), leveraging cutting-edge transformer architectures to bridge the gap between artificial intelligence and compassionate care.

Key Capabilities

Multiclass Emotion Recognition — Identifies 6 distinct emotional states in clinical dialogues
Healthcare-Optimized — Specifically trained on medical conversation data
Production-Ready — Deployable via REST API for real-time inference
Lightweight & Efficient — Built on DistilBERT for fast inference

🎯 Emotion Categories

Our model classifies emotional states into 6 clinically-relevant categories:

Category	Description
😐 Neutral	Objective, non-emotional statements
😰 Anxiety/Fear	Patient expresses worry, concern, or fear
😠 Anger/Frustration	Patient shows frustration or displeasure
😢 Sadness/Helplessness	Patient feels down or hopeless
🤔 Confusion/Doubt	Patient expresses uncertainty or questions
🙏 Gratitude/Relief	Patient conveys thanks or relief
