A decoupled, ultra-lightweight machine learning pipeline designed for low-latency edge deployment, automated avian species tracking, and interactive audio streaming.
|
| 29 |
+
|
| 30 |
+
By leveraging **Prototypical Contrastive Learning (ProtoCLR)** backbones combined with advanced topological manifold compression (**UMAP & HDBSCAN**), this system projects complex audio waveforms onto a dense, 2D geometric map. The resulting production architecture handles **168 unique biological species** across **149 autonomous eco-acoustic clusters** natively in a client browser window with sub-second latency—completely bypassing the need for compute-heavy cloud inferencing heads.

## 🛠️ The System Architecture Problem & Our Solution
|
| 35 |
+
|
| 36 |
+
### Our Decoupled Geometric Solution
|
| 37 |
+
This repository implements a **decoupled mathematical pattern**. Heavy feature extraction is processed upfront. The complex high-dimensional latent space is then permanently compressed into a frozen geometric lookup coordinate plane. The client device only runs low-compute spatial distance algorithms, achieving zero-lag edge inference.

## 🔬 Core Engineering Pillars
|
| 42 |
+
|
| 43 |
+
### 1. High-Ratio Manifold Compression
|
| 44 |
+
Instead of forcing edge hardware to hold dense classification layer weights, we isolate the 512-dimensional floating-point latent vectors generated by the transformer. We utilize **UMAP (Uniform Manifold Approximation and Projection)** to topology-map this high-dimensional array down to a highly constrained 2D coordinate vector (X, Y). This slashes the database RAM footprint by over **99%** while preserving semantic biological boundaries.
|
| 45 |
+
|
| 46 |
+
### 2. Acoustic Domain Shift Mitigation (augment.py)
|
| 47 |
+
Pre-trained foundation models are typically trained on pristine, studio-grade wildlife audio recordings, causing them to fail frequently in noisy consumer spaces. To bridge this gap, our data preparation pipeline routes clean data shards through a custom acoustic corruption environment mimicking real-world conditions.
