Learn how Semantic Kernel brings enterprise-grade agent capabilities to .NET and Python applications with planners, plugins, memory integration, and deep Azure ecosystem support.
Learn how to build a semantic memory system for AI agents using text embeddings, similarity thresholds, and memory consolidation to retrieve the most relevant facts from past interactions.
Build an intelligent autocomplete system that suggests semantically relevant queries as users type, combining query embeddings with popularity weighting and user personalization for a superior search experience.
Elasticsearch hybrid search bm25 dense vector knn documentation: Configure Elasticsearch for hybrid search that combines traditional BM25 keyword matching with dense vector kNN search, giving you the precision of neural retrieval with the reliabil…
Master the essential metrics for evaluating semantic search quality — nDCG, MRR, and Recall@K — with practical Python implementations, test set creation methodology, and benchmarking workflows.
Build a semantic code search engine that finds relevant functions and classes by intent rather than identifier names, using code-specific embeddings from CodeBERT and AST-aware parsing to understand code structure.
Master asyncio.Semaphore, token bucket, and sliding window rate limiters to control concurrent LLM API requests. Includes retry-after handling and adaptive throttling.
Master sentiment analysis techniques for AI agents, including aspect-based sentiment, fine-grained emotion detection, and strategies for integrating sentiment scores into agent routing and escalation logic.
Implement real-time sentiment analysis that detects frustrated or angry customers during support interactions and triggers automatic escalation to senior agents before the situation deteriorates.
