Retrieval System Evaluation - Industry should prioritize fast and inexpensive evaluations (fast evals) using query and document pairs to enable rapid experimentation [7] - Industry can leverage LLMs to generate queries, but should focus on aligning synthetic queries with real-world user queries to avoid misleading results [9][11] - Industry can empirically validate the performance of new embedding models on specific data using fast evals, rather than relying solely on public benchmarks like MTeb [12] - Weights & Biases chatbot analysis reveals that the original embedding model (text embedding three small) performed the worst, while voyage 3 large model performed the best, highlighting the importance of data-driven evaluation [17][18] Output Analysis and Product Development - Industry should extract structured data from user conversations (summaries, tools used, errors, satisfaction, frustration) to identify patterns and inform product development [28][29] - Industry can use extracted metadata to find clusters and identify segments for targeted improvements, similar to how marketing uses user segmentation [29][26] - Cura library enables summarization, clustering, and aggregation of conversations to compare evals across different KPIs, helping to identify areas for improvement [32] - Industry should focus on providing the right infrastructure and tools to support AI agents, rather than solely focusing on improving the AI itself [39] - Industry should define evals, find clusters, and compare KPIs across clusters to make informed decisions on what to build, fix, and ignore [40][41] - Industry should monitor query types and performance over time to understand how the product is being used and identify opportunities for improvement [45]
