title: "AI Image Recognition System"
date: 2026-03-15
categories: [AI, Computer Vision]
tags: [Deep Learning, TensorFlow, Python, PyTorch]
github: https://github.com/yourusername/ai-image-recognition
excerpt: "Efficient image recognition system using modern deep learning techniques"
---

## Overview

An end-to-end image recognition system achieving 94% accuracy on ImageNet dataset using EfficientNet architecture.

## Problem

Traditional image recognition systems had high latency and memory requirements, making them unsuitable for edge devices.

## Solution

Implemented EfficientNet with knowledge distillation and quantization:
- 5x faster inference than standard models
- 50% memory reduction through quantization
- Maintained 94% accuracy
- Supports real-time video processing

## Performance Metrics

| Metric | Value |
|--------|-------|
| Accuracy | 94.2% |
| Inference Time | 45ms |
| Model Size | 12MB |
| Supported Devices | GPU, CPU, TPU |

## Architecture Diagram

Input Image → Preprocessing → EfficientNet-B4 → Classification Head → Output ↓ Knowledge Distilled ↓ Quantized (INT8)

Breaking Changes

⚠️ Configuration: Old config format still supported but deprecated. Migration guide

Known Limitations

  • Fuzzy matching requires Python 3.11+
  • libmagic optional dependency recommended for best results
  • macOS support still experimental

Managing Categories & Tags

Understanding Categories vs Tags

Categories

  • Broad groupings (AI, DevOps, Web, Systems)
  • Usually 5-10 categories total
  • Appear in project metadata
  • Good for site navigation

Tags

  • Specific keywords (Python, Docker, Linux, AWS)
  • Can have many tags (50+)
  • Help with search and discovery
  • More granular than categories

Adding Categories

Edit _config.yml:

1
2
3
4
5

# Add more categories in projects collection
collections:
  projects:
    output: true
    permalink: /projects/:name/

Then use in projects:

1
2
3
4

---
title: "My Project"
categories: [AI, Web]
---

Adding Tags

Just use in front matter - no configuration needed:

1
2
3
4

---
title: "My Project"
tags: [Python, Docker, AWS, Linux]
---

Common Category Suggestions

  • AI: Artificial intelligence, machine learning
  • Web: Web development, frontend, backend
  • Systems: Operating systems, embedded, drivers
  • DevOps: Infrastructure, deployment, CI/CD
  • Tools: CLI tools, utilities, libraries
  • Documentation: Guides, tutorials, references
  • Research: Academic work, papers, experiments

Tag Best Practices

✓ Use lowercase and hyphens for multi-word tags
✓ Use consistent naming (not both “python” and “Python”)
✓ Keep tags specific but not overly granular
✓ Review existing tags before adding new ones

Customization

Changing the Theme Skin

Edit _config.yml:

1

minimal_mistakes_skin: "dark"  # Current

Available skins:

  • air - Light, minimal
  • aqua - Blue-tinted
  • contrast - High contrast
  • dark - Dark mode (recommended for portfolios)
  • dirt - Brown, warm tones
  • neon - Bright, vibrant
  • plum - Purple theme
  • sunrise - Orange/yellow

Try different skins:

1

minimal_mistakes_skin: "aqua"

Then commit and GitHub Pages rebuilds automatically!
