The FedCSIS 2026 is organized in Riga by the Riga Technical University. FedCSIS 2026 is technically sponsored by a large number of IEEE units (including six Sections from Region 8) and other professional organizations (for the full list, see the conference site – right hand side). FedCSIS 2026 is organized under patronage of: Poland Chapter of INFORMS, Latvian Information and communications technology association (LIKTA), Natinal Society of Informatics in Economics (NtiE), International Rough Set Society (IRSS), Academic Forum, Web Intelligence Consortium (WIC), Polish Neural Network Society (PNNS), European Society for Fuzzy Logic and Technology (EUSFLAT), and Polish Artificial Intelligence Society (PSSI). Reports from past editions of FedCSIS can be found in the Archive section of the conference WWW site. * \*\*\* Statement concerning Generative AI: Recognizing the developing issue that affects all academic disciplines (including conference and publications), we would like to explicitly state that, in principle, papers that include unedited text generated from Generative AI (GenAI), including large language models, are prohibited. If the author(s) uses GenAIs to prepare technical aspects of the research (e.g., use of GenAI-generated program code in experiments or simulations), this fact must be clearly marked in the paper, along with an analysis of the impact of this approach on the research results. In addition, it is permissible to use GenAI models at the stage of editorial correction, as long as the changes made are minor and do not substantively affect the article. If, at any time after the conference, it will be discovered that an LLM was explicilty used (and not properly recognized) such contribution will be retracted from the post-conference publication. Overall, it should be emphasized that full responsibility for the content of the publication lies with the author(s). Therefore, any inappropriate, or unethical, use of GenAI models in the preparation of an article may result in its immediate rejection.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!
