Prototype Inspection Day<\/figcaption><\/figure>\n\n\n\n

From Public Validation to Pipeline Implementation<\/h2>\n\n\n\n

All of our efforts this week were geared toward one major goal: validating our new foundation-model strategy with the wider UF community and beginning the core implementation of our self-supervised pipeline. After a successful presentation at the Prototype Inspection Day (PID), Team BeatNet is now fully focused on building the components necessary to pre-train our model on large-scale datasets.<\/p>\n\n\n\n

This week was about turning plans into concrete action\u2014coding the contrastive learning framework, benchmarking encoder backbones, and preparing scripts for downstream fine-tuning.<\/p>\n\n\n\n

Key Accomplishments This Week<\/h2>\n\n\n\n

Foundation-Model Strategy Defined:<\/strong>Successful Prototype Inspection Day (PID)<\/strong>
We presented our prototype progress and foundation-model strategy to UF faculty and alumni. Judges praised the team\u2019s clear communication and cohesive technical direction. Dr. Chenhao Wang highlighted our clarity, Dr. Tingsao Xiao called our foundation-model approach \u201cintuitive and reasonable,\u201d and Dr. Catia Silva encouraged us to begin embedding implementation as soon as possible.<\/p>\n\n\n\n

Contrastive Learning Pipeline Initiated<\/strong>
We began implementing the SimCLR-style contrastive learning pipeline, developing an augmentation module that generates positive pairs through noise, jitter, and scaling\u2014an essential step toward robust patient-invariant embeddings.<\/p>\n\n\n\n

Downstream Pipeline Development<\/strong>
In parallel, we started building the downstream fine-tuning workflow to adapt pretrained embeddings for arrhythmia classification and later for fiducial landmark regression.<\/p>\n\n\n\n

Encoder Benchmarking<\/strong>
We benchmarked multiple 1D encoder backbones\u2014including ResNet1D and EfficientNet1D\u2014to identify the optimal architecture for feature extraction efficiency and downstream transferability.<\/p>\n\n\n\n

Improved Communication Flow<\/strong>
Following judge feedback, the team is also refining presentation visuals, ensuring balanced speaking roles, and better illustrating the link between preprocessing, embedding, and disease classification.<\/p>\n\n\n\n

<\/a>Next Steps: Pre-training and Visualization<\/h2>\n\n\n\n

Next week, we will execute the first pre-training runs on the PTB-XL dataset, finalizing and debugging the contrastive learning script. We will develop a t-SNE visualization notebook to evaluate whether embeddings effectively cluster normal and arrhythmic segments, and improve visualization of time-positional encoding within our Transformer prototype.<\/p>\n\n\n\n

We will also begin preparing documentation for the upcoming System Level Design Review (SLDR) and conduct internal comparisons between baseline and foundation-model performance.<\/p>\n\n\n\n
