Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If quantum computing is integrated into deep learning models for time-series forecasting, then forecasting speed and accuracy are improved, but device complexity increases
Solution Approach 1:
The patent uses a quantum compute device as an intermediary component that specifically handles weight optimization in the deep learning model. Rather than replacing the entire classical computing system, the quantum device acts as a specialized co-processor that receives weight parameters, performs quantum-based optimization, and returns optimized weights to the classical system. This mediator approach enables quantum-enhanced forecasting accuracy while isolating the complexity to a dedicated component.
Solution Approach 2:
The forecasting system is segmented into distinct functional components: a classical computing portion that handles data preprocessing and model inference, and a quantum computing portion that specializes in weight optimization. This segmentation allows each component to operate at its optimal capability level, with the quantum processor focused solely on solving the complex optimization problem of finding optimal weight parameters for the deep belief network.
2Productivity
If quantum computing is used to optimize deep learning model weights, then training efficiency is improved, but computational resource requirements increase
Solution Approach 1:
The patent applies quantum computing resources partially, using them only for the specific task of weight optimization rather than for the entire machine learning pipeline. The quantum compute device processes weight parameters in a targeted manner, applying quantum algorithms only where they provide maximum benefit (in the optimization of the deep belief network weights) while leaving other computational tasks to classical systems.
3Measurement precision
If deep learning models are used for time-series forecasting, then predictive accuracy is improved, but computational time increases
Solution Approach 1:
The patent fundamentally changes the parameter optimization process by transitioning from classical gradient-based methods to quantum computing algorithms. This parameter change in the optimization approach enables the system to explore the weight space more efficiently, finding optimal parameters that maximize predictive accuracy while reducing the computational time required for training and fine-tuning the deep learning model.

AI summary
An apparatus including a Deep Belief Network is configured to receive, via a processor, input data. The processor is caused to initialize, based on the input data, weights for a learning model of the DBN. The processor is further caused to generate, via the learning model, a representation of the input data. The weights, the input data, and the representation is to be transmitted to a quantum compute device. The processor is caused to receive sampled values from the quantum compute device using an optimization function associated with the quantum compute device. The processor is further caused to update, based on the sampled values, the weights to train the learning model to produce a trained learning model. The trained learning model is configured to generate an updated representation of the input data. The processor is further caused to generate, via a regression layer, output data based on the updated representation.
