INT8 Quantization Shrinks TinyML ECG Model by 60%

By PulseAugur Editorial · [1 sources] ·

An experiment explored the impact of INT8 quantization on a TinyML model designed for ECG arrhythmia detection. By reducing the numerical precision from 32-bit floating point (FP32) to 8-bit integers (INT8), the model size was significantly decreased. This compression resulted in a reduction from 87.5 KB to 34.6 KB, making the model approximately 60% smaller, while the experiment aimed to assess how much performance could be sacrificed before the trade-off became unacceptable. AI

IMPACT Demonstrates a method for reducing model size in TinyML applications, potentially enabling deployment on resource-constrained devices.
