- MLflow & DVC tutorials
- Multi-modal models like CLIP
MilestoneCan architect and manage a complete, versioned, and automated system that combines multiple retrieval methods for a complex application like a multi-modal search engine.
-
Leadership & Innovation
8 weeksGoals
- Evaluate and prototype next-generation embedding and retrieval techniques (e.g., graph-based)
- Design multi-region, fault-tolerant vector database deployments
- Lead technical design reviews and mentor junior engineers on the team
Resources
- Latest research from conferences like NeurIPS, ICLR (read key papers)
- Case studies on large-scale deployments from tech blogs (Uber, Pinterest, Spotify)
- Leadership and communication workshops
MilestoneCan set the technical strategy for an organization's embedding infrastructure, evaluate emerging technologies, and lead the implementation of a large-scale, mission-critical system.
Practice Projects
Apply your skills with hands-on projects. Ordered by difficulty.
Semantic Book Search Engine
BeginnerBuild a local search engine for a corpus of book descriptions (e.g., from Project Gutenberg). Ingest text, chunk it, generate embeddings with a pre-trained model, store in FAISS, and build a simple CLI or web UI for semantic queries.
Fine-tune a Domain-Specific Embedding Model
IntermediateCollect or create a dataset of (query, relevant document) pairs for a specific domain (e.g., cooking recipes, Stack Overflow questions). Fine-tune a pre-trained sentence-transformer model using contrastive loss and evaluate its performance improvement on a hold-out set.
Production-Ready Hybrid RAG API
IntermediateExtend a basic RAG pipeline into a production-grade service. Containerize the application, implement hybrid search (vector + keyword) using a Weaviate or Pinecone index, add a re-ranking step, and deploy it on a cloud service with basic monitoring.
Benchmarking Vector Database Performance
AdvancedDesign a comprehensive benchmark to compare the performance (throughput, latency, recall, cost) of 2-3 vector databases (e.g., Milvus, Qdrant, Elasticsearch kNN) under various data loads and query patterns. Publish the results and analysis.
Multi-Modal Search Prototype
AdvancedBuild a prototype system that allows users to search a dataset of images using text descriptions, and vice-versa. Use a model like CLIP to generate aligned text and image embeddings, store them in a vector DB with metadata, and build a simple search interface.
