We believe in full transparency about how our AI works. Here's a detailed breakdown of what the model evaluates, how it was trained, and what its limitations are.
Introduction
At RateMyFeet, we believe that if you're trusting an AI system to evaluate something as personal as your body, you deserve to know exactly how it works.
This article pulls back the curtain on our AI model — covering its architecture, training methodology, what it evaluates, and, just as importantly, what it doesn't. Transparency isn't just a buzzword for us. Understanding the technology helps you interpret your results thoughtfully.
What Does the AI Actually Evaluate?
Our model analyzes visual characteristics along several dimensions. These are aesthetic parameters — not medical assessments or value judgments.
Shape and Proportionality
The model assesses the visual shape of the feet relative to the frame of the body visible in the image. This includes toe alignment, arch profile, and how the shape relates to the overall proportions.
Symmetry
The model measures visual symmetry between the left and right foot. Almost no one is perfectly symmetrical, and the model is calibrated with this reality in mind. Minor asymmetry has minimal impact on ratings.
Skin Quality
The model evaluates visible skin characteristics including evenness of tone, texture, and surface consistency. This is assessed purely as a visual parameter — it doesn't assess skin health.
Presentation and Image Quality
Lighting, angle, resolution, and framing all affect how an image is perceived. Our model accounts for image quality factors to avoid penalizing poor photography. However, extreme issues (heavy blur, very low resolution) will affect reliability.
How the Model Was Trained
Our AI model is a convolutional neural network (CNN) trained through a multi-phase process:
Phase 1: Base Visual Understanding
The foundational model was pre-trained on large-scale image datasets to develop general visual recognition capabilities — shapes, textures, proportions, and spatial relationships.
Phase 2: Aesthetic Calibration
The model was fine-tuned on a curated dataset where images were rated by diverse panels of human evaluators across multiple dimensions. The panel was intentionally diverse to minimize systematic bias.
Phase 3: Bias Auditing and Correction
- Skin tone: Tested across the full spectrum to ensure ratings don't systematically differ based on race or ethnicity.
- Size bias: Calibrated to avoid favoring any particular size range.
- Age-related features: Trained to evaluate aesthetics without penalizing natural age-related changes.
What the AI Does NOT Do
- It does not provide medical assessments. It cannot detect health issues or serve as a screening tool.
- It does not judge you as a person. The output is a computational analysis of visual parameters — it says nothing about your worth.
- It does not predict others' opinions. The output represents a mathematical aggregation of training data.
- It does not store or share images. Images are processed in real-time and are not retained.
Understanding Your Results
- Context matters: The same feet photographed in different lighting may produce different scores.
- Scores are relative, not absolute: A rating exists on a scale representing statistical assessment, not objective truth.
- Variation is normal: Multiple images may produce slightly different scores.
- The model improves over time: We continuously refine based on feedback and bias auditing.
Our Ethical Commitments
- Privacy first: Your images belong to you. We employ encryption in transit and do not retain images beyond processing.
- No exploitation: We do not sell data, share images, or monetize submissions beyond the direct service.
- Body-positive framing: Our system is designed to be informational, not harmful.
- Continuous improvement: We actively seek and incorporate feedback, particularly regarding bias.
Limitations of Any AI Rating System
- AI models learn from human-generated data, which inevitably contains cultural biases.
- A 2D image is a limited representation of a 3D body.
- Aesthetics are inherently subjective — any numerical rating is a simplification.
- AI cannot assess confidence, personality, movement, or other non-physical factors.
Conclusion
Our AI is a tool — hopefully an interesting and fun one — but it's not an authority. It can give you a data point, a perspective, a starting point for reflection. What it can't do is tell you anything definitive about your attractiveness or worth.
We've built this system with as much care, fairness, and transparency as possible. If you ever have questions about how the model works, concerns about bias, or suggestions for improvement, we want to hear from you.
