  2. Emotion Classification with Transformers

    5 weeks
    Goals
    • Fine-tune pre-trained transformer models for multi-label emotion classification
    • Work with benchmark emotion datasets (GoEmotions, IEMOCAP, MELD, EmoBank)
    • Evaluate models using precision, recall, F1, confusion matrices, and per-emotion breakdowns

    You can fine-tune a BERT-based model on GoEmotions achieving competitive F1 scores and log experiments with W&B.

  3. Multimodal Emotion Detection - Voice & Vision

    5 weeks
    Goals
    • Extract acoustic features (MFCCs, pitch, energy, jitter, shimmer) from speech using Librosa/Praat
    • Implement facial expression recognition with OpenCV and MediaPipe facial action units
    • Build early/late fusion architectures combining text, audio, and visual modalities
    Resources
    • IEMOCAP and MELD multimodal datasets

    You can build a multimodal pipeline that fuses text and speech signals to classify emotions in conversational video clips.

  4. Production Pipelines, MLOps & Bias Auditing

    4 weeks
    Goals
    • Deploy emotion models as real-time APIs using FastAPI or gRPC with Docker/Kubernetes
    • Set up monitoring for model drift, latency, and emotional distribution shifts
    • Conduct systematic bias audits across gender, age, ethnicity, and language using Fairlearn and custom scripts

  5. Applied Emotion Intelligence for CX Products

    4 weeks
    Goals
    • Integrate emotion detection into customer journey touchpoints (chatbots, IVR, support tickets, video calls)
    • Design emotion-aware routing and escalation logic in contact center platforms
    • Build executive-facing dashboards translating emotion analytics into CX metrics and business recommendations
    Resources
    • AWS Contact Center Intelligence documentation

Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

GoEmotions Multi-Label Emotion Classifier

Beginner

Fine-tune a DistilBERT model on Google's GoEmotions dataset to classify text into 27 emotion categories. Build a Streamlit demo that takes user input and displays real-time emotion probability distributions with a radar chart.

~25h
Transformer fine-tuningMulti-label classificationEvaluation metrics (micro/macro F1)

Voice Emotion Recognition from Call Center Audio

Intermediate

Build a speech emotion recognition pipeline on the IEMOCAP or RAVDESS dataset. Extract acoustic features (MFCCs, pitch, energy) with Librosa, train a CNN-LSTM model, and build a real-time inference demo that classifies emotion from microphone input.

~35h
Audio signal processingAcoustic feature extractionSequential deep learning (CNN-LSTM)

Multimodal Emotion Fusion for Video Conversations

Advanced

Build a multimodal emotion recognition system on the MELD dataset that fuses text (dialogue), audio (prosody), and visual (facial expressions) modalities using cross-modal attention. Evaluate per-modality and fused performance, and create a timeline visualization of emotional dynamics in a conversation.

~60h
Multimodal fusion architecturesCross-modal transformersTemporal emotion analysis

Emotion-Aware Chatbot with LangChain

Intermediate

Build a conversational agent using LangChain and OpenAI that detects the user's emotion in each turn and dynamically adjusts its tone and response strategy. Include an emotion memory buffer that tracks emotional trajectory and triggers escalation for sustained negative emotions.

~30h
LangChain orchestrationEmotion-aware prompt engineeringConversational state management

Bias Audit Dashboard for Emotion Models

Advanced

Build an automated bias auditing tool that evaluates an emotion model's performance across demographic slices (gender, age, ethnicity, language). Generate disaggregated metrics, visual fairness reports, and a Gradio dashboard that lets stakeholders explore model behavior on specific subgroups.
