+# Open-Source Demonstration Reproduction of MIRA
+
+This repository provides an **open-source demonstration reproduction** of  
+**MIRA: Medical Time Series Foundation Model for Real-World Health Data**  
+(arXiv: https://arxiv.org/abs/2506.07584).
+
+The goal of this demo is to offer a **fully accessible and reproducible version** of the MIRA framework, trained **exclusively on publicly available time-series datasets**, without using any proprietary or sensitive clinical data.  
+It is designed to showcase the core ideas of MIRA rather than replicate the full-scale training described in the original paper.
+
+---
+
+## Overview
+
+This demonstration model reproduces the key architectural components of MIRA:
+
+- **Continuous-Time Rotary Positional Encoding (CT-RoPE)**  
+  Enables geometric time encoding for irregularly sampled signals. The **CT-RoPE temporal unit is set to 0.1**.
+
+- **Frequency-Specialized Mixture-of-Experts (MoE)**  
+  Allows experts to specialize on low- vs. high-frequency clinical patterns.
+
+- **Neural ODE–Based Continuous Dynamics Modeling**  
+  Captures long-range physiological trajectories with continuous-time formulations.
+
+---
+
+## Notes
+
+- This model is a **demonstration reproduction**, not the full-scale MIRA model.  
+- Performance will differ from the original paper due to dataset differences.
