PROFILE
Davide
Davide Marchi developed advanced explainable AI features for the belgio99/smartfactory repository, focusing on retrieval-augmented generation (RAG) and LIME-based forecasting explanations. He designed modular architectures for attribution tools, enabling traceability from model outputs to source documents and supporting multi-context, multilingual, and flexible input scenarios. His work included integrating embeddings for improved retrieval accuracy, optimizing context management, and enhancing deployment flexibility with CPU-based embedding support. Using Python, PyTorch, and JSON, Davide refactored codebases, improved test coverage, and implemented robust error handling. These contributions addressed model transparency, reliability, and usability, laying a foundation for production-grade explainability and cross-team reuse.

Dec 1, 2024December 2024 monthly summary for belgio99/smartfactory: Focused on stability, performance, and scaling XAI capabilities. Key outcomes span context management, scoring customization, RagExplainer readiness, deployment flexibility, and UX improvements. Key achievements: - Context handling improvements: allow adding context without duplicates and introduce tokenize_context parameter (commits c09bd1bbdf4c701e4fa961877a23b6685e9b4fab; 783cb737cb235ff48e6a4999d2b8a4b1637c28fb). - Configurable scoring and default scorer: add choosable scoring function and switch default scorer from fuzz.token_set_ratio to fuzz.partial_ratio (commits 851067bdce071100f92f1835960380774d99affc; af867ab0e50c92078c86a82b6065c786cd4422e2). - RagExplainer embeddings integration and mapping refactor: add support for embeddings and update threshold; refactoring to include original context in mappings (commits 3a74c09de997d91db5e2d1e006fd840313b342c0; 4df7068b3442833ba33a0afe9cb979e916f6c73e; e28eb3b2c41d986ba526a13a2e2c07dfeb63b527; ae544a7e90db1f32afe3b75582412c13cef543ae). - CPU embedding placement and readiness: move embeddings to CPU by default and ensure initial embedding on CPU while preserving MPS/CUDA usage (commits 1d94fa8b1b491b66445bd580a29977956d6273b8; 079d3b7fb390fda00c999a0bf9ec39d6aebc8fb2). - XAI multilingual and GUI updates: multilingual support and JSON parser; GUI explanation updates (commits 9d667cc40c339d0c988edfb2e7bb11f7cbfbe76c; d9aff5a05df6b0d24d807d7dafff069ff18b211b). Major impact and business value: - Improved retrieval accuracy and explainability through embeddings, richer context, and configurable scoring. - Greater deployment flexibility and cost efficiency with CPU-based embeddings and robust RagExplainer integration. - Improved user experience and accessibility via multilingual support and clearer GUI explanations. - Enhanced reliability with input validation, bug fixes, and maintenance cleanups to reduce risk and tech debt. Technologies/skills demonstrated: - Advanced NLP retrieval and explanation pipelines (RagExplainer, embeddings, mapping). - Memory/compute optimization (CPU embeddings, reduced LIME samples for speed). - API flexibility and backward compatibility (optional training_outputs, defaults adjustments). - JSON parsing/validation, multilingual UX, and robust error handling.

Nov 1, 2024November 2024 (2024-11) monthly summary for belgio99/smartfactory: Two major AI explainability capabilities were delivered: RAG Explainability Attribution Tool and LIME-based Forecasting Explanations. The RAG tool introduces a modular ResponseAttributor architecture, supports multiple reference contexts, class-based attribution, improved input validation, tokenization, and context-based formatting; initial version delivered with iterative refinements and test-driven improvements. The LIME-based forecasting feature adds local explanations for predictive models, with support for flexible input types and multidimensional time-series data. In parallel, tests and test coverage for XAI_rag were enhanced, with updated scenarios to improve reliability and future production-readiness. These contributions collectively improve model traceability from outputs to source documents, boost stakeholder trust, and lay the groundwork for production-grade explainability, enabling better debugging, compliance, and informed decision-making. Technologies demonstrated include Python-based XAI patterns, LIME, RAG explainability methods, modular refactoring (ResponseAttributor), and data structures like context as a list of source-context tuples with reference numbering.
