Beginner Level
What Is It?
Embeddings are dense vector representations of text, time series, or market states that capture semantic relationships.
Origin
Popularized by Word2Vec in 2013 and scaled by transformer models after 2017.
Why It Matters
Embeddings allow AI to compare and cluster market concepts, news, and price action efficiently.
Intermediate Level
Market Mechanics
Financial data (earnings transcripts, news, order flow) is converted into high-dimensional vectors for similarity search and clustering.
How It Behaves
Similar market conditions map to nearby vectors, enabling rapid retrieval and pattern matching.
Key Data to Watch
- Embedding similarity scores
- Cluster coherence during regime changes
Advanced Level
Institutional Behavior
Quant funds use embeddings for semantic search across filings, news, and historical events.
Professional Use Cases
- News-to-price impact modeling
- Cross-asset similarity detection
- Memory retrieval in RAG systems
AI Interpretation in Systems Like Arkhe
- Sentiment Agent: Embeds news and social data for real-time context.
- ML Agent: Maintains vector memory of past market states.
Key Takeaways
Embeddings are the language in which modern AI understands markets.
