After weeks of tuning, testing, and validating, we are now converging toward final design decisions\u2014solidifying lead selection, strengthening reproducibility, and unifying the entire system into a single deployable prototype.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Rather than asking <em>\u201cCan it work?\u201d<\/em>, we are now asking <em>\u201cCan it work consistently, cleanly, and in production?\u201d<\/em><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">Key Accomplishments This Week<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Finalized Lead Selection Through Benchmarking<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">We completed a detailed comparison between Lead I and Lead II for single-lead classification. Results showed that Lead II improves AUROC for infarction detection, helping close the previous performance gap. This marks an important architectural decision for final deployment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Integrated Reproducibility Protocols<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">To ensure scientific rigor, we implemented fixed random seeds across training runs. Our model now consistently achieves 98\u201399% accuracy across repeated experiments, strengthening confidence in stability and repeatability.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Built a Unified End-to-End Prototype<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">We developed a fully integrated interface that visualizes raw ECG signals, overlays PQRST fiducial points, and displays saliency maps in one application. This transforms our system from separate scripts into a cohesive diagnostic tool.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Refined Training and Learning Rate Strategy<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">We experimented with higher learning rates (0.005) versus lower rates. While higher rates accelerated training, lower rates produced smoother convergence and better validation stability\u2014guiding our final optimization strategy.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">Next Steps: Precision and Deployment Readiness<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In the coming week, we will:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Close the T-Wave Gap:<\/strong> Improve T-wave detection accuracy, our current weakest fiducial component.<\/li>\n\n\n\n<li><strong>Implement Advanced Physiological Post-Processing:<\/strong> Eliminate impossible outputs (e.g., duplicate T-waves or unrealistic proximities).<\/li>\n\n\n\n<li><strong>Draft Dual Documentation Tracks:<\/strong> One research-oriented manuscript and one technical report aligned with future FDA pathways.<\/li>\n\n\n\n<li><strong>Begin Cloud Deployment Research:<\/strong> Explore Azure hosting to mirror sponsor infrastructure.<\/li>\n\n\n\n<li><strong>Validate Against Sponsor Data:<\/strong> Cross-check Lead II outputs with real-world patient samples.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<p class=\"wp-block-paragraph\">We are no longer just optimizing models\u2014we are shaping a clinically aligned, reproducible, deployment-ready ECG AI system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">See you next week!<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>From Performance to Production: Finalizing Lead Strategy and System Integration This week marked a transition from experimentation to refinement.
