Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Detecting counterfeit pharmaceuticals, particularly diluted liquid formulations, is challenging due to their similar appearance to real drugs and the need for extensive training data, which is time-consuming and costly to generate.
Innovation Solution
A generative adversarial neural network (GAN) is used to enhance the robustness of a drug dilution detection system by generating additional training data from seed data, including noise vectors and captured images, to differentiate between real and counterfeit products, and determine dilution levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual training data generation is used, then detection accuracy can be achieved, but time consumption and cost increase significantly
Solution Approach 1:
The patent uses generative adversarial networks to create synthetic training data that copies the essential characteristics of real diluted drug samples. The GAN generates realistic images of diluted pharmaceutical products with various dilution levels, providing sufficient training data without manual collection. This copying approach maintains detection accuracy while eliminating time-consuming manual data generation processes.
2Reliability
If extensive training data is collected manually, then model robustness improves, but cost and time resources are consumed
Solution Approach 1:
The system implements self-service training data generation through automated GAN pipelines. The generative model automatically produces diverse training samples with varying dilution concentrations without human intervention. This self-service mechanism ensures sufficient training data volume for robust model performance while dramatically improving training efficiency and reducing resource consumption compared to manual data collection methods.
3Device complexity
If traditional detection methods are used, then simplicity is maintained, but detection accuracy for diluted drugs decreases
Solution Approach 1:
The patent replaces traditional mechanical/optical detection methods with AI-based machine learning systems. Instead of relying on simple physical measurement devices, the solution uses trained neural networks that analyze product images and spectral data. This substitution significantly improves dilution detection accuracy by learning complex patterns from training data, while the automated nature of the system maintains operational simplicity despite the increased computational complexity underneath.
Data Source
AI summary
Techniques are provided detecting diluted drugs using machine learning. Measurements and images corresponding to a product are obtained, wherein the product is formulated as a liquid, and wherein the measurements and images capture physical, spectral, optical, and/or chemical properties of the product. The measurements and images are provided to a machine learning model, wherein the machine learning model is trained using data generated from interactive learning modules (e.g., a generative adversarial network). The machine learning model detects whether the product or chemical is a real or counterfeit product. In addition, these techniques may be used by practitioners (e.g., medical personnel dispensing a prescribed dosage of a drug with a specific dilution level) to detect prescription errors at the point of administration.
