The 'Animal Face Test,' which has gained huge popularity on SNS, is more than just fun; it's the result of cutting-edge AI technology. Behind the process of identifying puppy, cat, or rabbit faces from a single photo lies complex mathematical models and data learning processes.
1. Convolutional Neural Network (CNN)
The core technology of the AI Animal Face Test is a deep learning algorithm called CNN. CNN is a neural network that mimics human visual processing and specializes in extracting 'features' from images. It analyzes subtle differences like the shape of eyes, the angle of the nose, and the thickness of lips, converting them into numerical data.
2. Teachable Machine and Transfer Learning
Choosey's animal test is based on the Google Teachable Machine library. It uses a technique called 'Transfer Learning.' We take a massive model that already knows how to distinguish objects by learning millions of images and fine-tune it specifically for the 'Animal Face' category. This allowed us to achieve high accuracy even with a limited amount of specific data.
1. Image Input (User photo upload)
2. Pre-processing (Face detection and resizing)
3. Feature Extraction (Extracting features via CNN)
4. Classification (Comparative analysis with learned data)
5. Result Output (Displaying the highest probability)
3. The Importance of Datasets
For an AI to accurately identify a 'cat face,' it needs data from thousands of photos of celebrities and people with cat-like features. The AI learns the common characteristics of these photos (e.g., sharp eyes, defined jawline) and remembers them as a 'pattern.' The more diverse and plentiful the training data, the more sophisticated the AI's judgment becomes.
4. On-Device AI and Security
One of the greatest advantages of the technology Choosey uses is Privacy Protection. In the past, photos were sent to a server for analysis, but using modern web technology (TensorFlow.js), the AI model can be executed directly within the user's smartphone or PC browser. This means your face photo is never sent to a server; it's processed locally and deleted immediately.
5. The Future of AI Technology
The Animal Face Test is a great example of how close AI has come to our daily lives. In the future, it will evolve into more personalized services, such as diagnosing personal colors or suggesting styles that fit your body type, beyond just finding animal look-alikes.
