What It Does

A production-ready Android application that detects Chickpea Fusarium Wilt from smartphone photos — fully offline, instant results, with bilingual disease advisory (English + Myanmar Unicode). Designed for smallholder farmers in Myanmar with no internet connectivity.

Key Results

  • 82.09% cross-domain accuracy on a real-world Myanmar field test set unseen during training
  • Model size: 0.870 MB after quantization — compatible with 2 GB RAM devices and Android 9.0+
  • Validated on 115 real physical Android devices via Google AI Edge Portal (private preview)
  • Worst-case inference: 73.7 ms on low-tier CPU-only hardware

What I Built

  • A novel hybrid CNN architecture combining SqueezeNet v1.1 with an attention mechanism — outperforming larger and more established architectures with a fraction of the parameters
  • An INT8 quantization pipeline delivering over 3× model compression with zero accuracy degradation
  • A personally collected field dataset from Myanmar farming communities, with expert agronomist annotation
  • A bilingual Android app (Kotlin, Jetpack Compose, Material Design 3, TFLite) supporting SDG 1 and SDG 2

Why It Matters

Most plant disease AI models are designed for high-end hardware or require cloud connectivity. This work targets the opposite end: low-cost devices, no internet, field conditions — making AI-assisted disease detection accessible to farmers who need it most.
