## Overview
|
| 45 |
+
|
| 46 |
+
**MyanNet V1** is a lightweight convolutional neural network (CNN) developed for **Burmese handwritten digit recognition**. The model was designed to achieve an excellent balance between recognition accuracy and computational efficiency, making it suitable for deployment on mobile, embedded, and resource-constrained devices.
|
| 47 |
+
|
| 48 |
+
Instead of maximizing accuracy through increasingly deeper networks, MyanNet V1 focuses on reducing computational complexity while maintaining competitive performance. The architecture combines **depthwise separable convolutions**, **batch normalization**, **global average pooling**, and **dropout regularization** to produce a compact yet highly effective classifier.
|
| 49 |
+
|
| 50 |
+
The model was trained and evaluated on the **Burmese Handwritten Digit Dataset (BHDD)**, containing **87,561 handwritten digit images** across ten Burmese numeral classes.

# Failure Cases
|
| 157 |
+
|
| 158 |
+
Representative misclassified samples produced by MyanNet V1.

|
| 162 |
+
</p>
|
| 163 |
+
|
| 164 |
+
Although misclassifications are rare, they primarily occur for ambiguous handwriting styles and visually similar digit shapes.

|
| 234 |
+
|
| 235 |
+
- Burmese handwriting recognition
|
| 236 |
+
- Educational software
|
| 237 |
+
- Mobile OCR systems
|
| 238 |
+

|
| 243 |
+
|
| 244 |
+
# Limitations
|
| 245 |
+
|
| 246 |
+
MyanNet V1 was trained exclusively on isolated handwritten Burmese digits contained in the BHDD dataset.
|
| 247 |
+
|
| 248 |
+
The model has **not** been evaluated on:
|
| 249 |
+
|
| 250 |
+
- Printed Burmese text
|
| 251 |
+
- Burmese characters
|
| 252 |
+
- Burmese words or sentences
|
| 253 |
+
- Historical manuscripts
|
| 254 |
+
- Camera-captured documents
|
| 255 |
+
- General OCR tasks
|
| 256 |
+
|
| 257 |
+
Performance outside the BHDD domain may differ significantly.
