-
Foundations of Text & NLP
6 weeksGoals
- Master Python for data manipulation and basic NLP tasks.
- Understand core NLP concepts: tokenization, stemming, POS tagging.
- Learn the theory behind named entity recognition.
Resources
- Coursera: Natural Language Processing Specialization (deeplearning.ai)
- Book: 'Natural Language Processing with Python' (NLTK)
- Kaggle: Intro to NLP course
MilestoneCan clean text data and use spaCy/NLTK for basic entity extraction using rule-based and simple ML models.
-
Deep Learning for NER
8 weeksGoals
- Understand transformer architecture and attention mechanisms.
- Learn to fine-tune BERT-family models for custom NER using HuggingFace.
- Master evaluation metrics (F1-score, confusion matrix) for sequence labeling.
Resources
- HuggingFace NLP Course (free)
- Papers: 'BERT: Pre-training of Deep Bidirectional Transformers'
- PyTorch/TensorFlow tutorials on sequence modeling
MilestoneCan prepare custom datasets, fine-tune a BERT model for NER, and rigorously evaluate its performance on a held-out test set.
-
LLM Orchestration & Prompt Engineering
6 weeksGoals
- Master advanced prompt engineering for entity extraction tasks.
- Learn to build RAG (Retrieval-Augmented Generation) and agent pipelines with LangChain.
- Integrate NER models into API-based applications.
Resources
- LangChain documentation and tutorials
- OpenAI API documentation
- DeepLearning.AI: Building Systems with ChatGPT API
MilestoneCan design a multi-step LangChain pipeline that uses an LLM for entity extraction, validates the output, and feeds it to a downstream tool.
-
Production Systems & CX Integration
6 weeksGoals
- Learn MLOps basics: containerization (Docker), CI/CD for ML.
- Understand real-time inference serving and monitoring.
- Study key CX metrics (CSAT, CES) to align model output with business goals.
Resources
- MLOps Zoomcamp (free)
- FastAPI for creating model serving endpoints
- Articles on model monitoring with Prometheus/Grafana
MilestoneCan deploy a fine-tuned NER model as a scalable, monitored API endpoint and articulate its impact on a customer experience metric.
Practice Projects
Apply your skills with hands-on projects. Ordered by difficulty.
Customer Support Ticket Entity Extractor
BeginnerBuild a system to extract key entities (order IDs, product names, issue types) from a dataset of customer support emails. Use spaCy or a pre-trained transformer model and evaluate performance.
Domain-Specific NER Fine-Tuning with HuggingFace
IntermediateFine-tune a BERT model on a niche dataset (e.g., biomedical abstracts, legal clauses) to recognize specialized entities. Focus on the end-to-end HuggingFace Trainer workflow.
LangChain-Powered Conversational Entity Agent
AdvancedCreate an agent that uses an LLM via LangChain to extract entities from a user's conversational query, then uses a tool to fetch relevant information about those entities (e.g., product details from a mock API).
Real-Time NER Microservice with FastAPI & Monitoring
AdvancedDeploy a fine-tuned NER model as a REST API using FastAPI. Containerize it with Docker, and set up basic monitoring to log prediction confidence and latency.
