Neural Network Aesthetic Rating via Pairwise Ranking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for rating aesthetic quality of digital images face challenges in accurately classifying images with quality falling between high and low ratings, providing inconsistent results due to subjective user opinions and binary classification systems, and failing to offer comprehensive explanations for ratings.
Innovation Solution
A neural network is trained using pairs of images with similar content and user ratings to reduce inconsistencies and provide accurate aesthetic quality scores, employing content-aware and user-aware sampling techniques to account for subjective differences and types of content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a binary classification system is used to rate digital images, then high and low quality images can be effectively distinguished, but images with quality falling between high and low ratings cannot be accurately classified
Solution Approach 1:
The patent changes the rating parameter from binary (high/low) to a continuous scale (e.g., 1-10 or 1-5 stars). The neural network outputs a continuous aesthetic quality score that can take any value within a range, enabling precise differentiation of images across the entire quality spectrum rather than forcing them into two discrete categories.
Solution Approach 2:
The patent transitions from a one-dimensional binary classification to a multi-dimensional continuous scoring system. Instead of simply categorizing images as high or low quality, the system provides ratings along a continuous dimension, allowing for nuanced differentiation of images with intermediate quality levels.
2Measurement precision
If conventional machine learning systems are used to rate aesthetic quality, then technical accuracy can be achieved, but inconsistent results occur due to subjective user opinions
Solution Approach 1:
The patent incorporates feedback mechanisms where the neural network learns from multiple user ratings for the same image. By aggregating and learning from these ratings, the system accounts for subjective variations while maintaining consistency. The model adjusts its predictions based on patterns in user feedback, reconciling individual subjective opinions into a reliable overall rating.
Solution Approach 2:
The patent creates a universal rating system that works across diverse image types and user preferences. The neural network is trained on a large dataset of images with varying aesthetic qualities and user ratings, enabling it to provide consistent evaluations that reflect general aesthetic principles rather than being biased toward specific subjective preferences.
3Device complexity
If conventional systems provide binary classification, then processing is simple, but comprehensive explanations for ratings are not provided
Solution Approach 1:
The patent segments the rating process into multiple components. Instead of providing a single binary outcome, the system breaks down the aesthetic quality assessment into multiple dimensions or attributes (e.g., composition, color, lighting, subject matter). Each attribute can be evaluated separately, providing users with detailed explanations of why an image received its overall rating.

AI summary
Systems and methods are disclosed for estimating aesthetic quality of digital images using deep learning. In particular, the disclosed systems and methods describe training a neural network to generate an aesthetic quality score digital images. In particular, the neural network includes a training structure that compares relative rankings of pairs of training images to accurately predict a relative ranking of a digital image. Additionally, in training the neural network, an image rating system can utilize content-aware and user-aware sampling techniques to identify pairs of training images that have similar content and/or that have been rated by the same or different users. Using content-aware and user-aware sampling techniques, the neural network can be trained to accurately predict aesthetic quality ratings that reflect subjective opinions of most users as well as provide aesthetic scores for digital images that represent the wide spectrum of aesthetic preferences of various users.
