Decentralized Systems & Applications

En este taller introductorio vamos a acercarnos a la **Teoría de Respuesta al Ítem (TRI)** de una manera práctica y accesible. La TRI sirve para entender mejor **cómo funcionan los ítems (preguntas) de un test y cómo miden una habilidad o rasgo**. Nos permite ver, por ejemplo, si un ítem es más fácil o más difícil, si discrimina bien entre personas con distinto nivel, y si funciona de manera consistente. También es una herramienta muy útil para seleccionar los mejores ítems, acortar tests sin perder calidad y diseñar escalas más precisas. A lo largo del encuentro, vas a: \- Construir una comprensión conceptual de sus ideas principales\. \- Aplicar este método usando R\. \- Aprender a interpretar sus resultados para entender mejor cómo funcionan los ítems y qué aportan a la medición\. Este taller es **introductorio** y está dirigido a personas con un **conocimiento básico de escalas psicométricas**. **No requiere conocimiento previo de Teoría de Respuesta al Ítem.** **Requerimientos:** * R: 4.5.1 (mínimo) * RStudio: 2025.05.1 (mínimo, descargar [aquí](https://posit.co/downloads/)) * Instalar los paquetes **tidyverse, mirt y ltm**

La atmósfera también es parte de la experiencia. Las luces cálidas, la música, el vino, las historias que aparecen alrededor de la mesa y esa sensación de terminar la noche pensando: “qué bueno haber venido”. ✨ Cena con desconocidos 📍 Colegiales, CABA 🗓 Sábado 16 de mayo 🕗 20 hs 👥 Cupos limitados 💵 $24.500 por persona Reserva con pago previo. 📩 Info e inscripción: 11 6220-1726 — Sabores y Conexión 🤍

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!
