Solution Overview
Problem
Current deep learning AI model training is laborious and inefficient, requiring extensive data balancing and long training times, with trained neural networks acting as 'black boxes' that need retraining for new questions, wasting computing power and time.
Innovation Solution
A method for initializing a neural network using time series data, where the network is run with input time series data until a stopping state is reached, allowing for efficient initialization and reduced training time by pre-setting internal values to match the modeled space, thereby saving energy and computational resources.

Engineering Contradiction Analysis
1Reliability
If traditional neural network training is performed from ground zero, then the model can be trained to achieve desired output, but the training process is laborious and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-initializing neural network weights using autoencoders trained on unlabeled data from the target domain before the main training task. This preliminary initialization step prepares the network with domain-relevant features, eliminating the need to start from random weights and significantly reducing subsequent training time while maintaining model accuracy.
2Reliability
If traditional neural network training is performed with extensive training sets, then model performance can be optimized, but computing power and resources are wasted
Solution Approach 1:
The patent performs preliminary unsupervised pre-training using autoencoders on large unlabeled datasets to learn domain-specific feature representations. This preliminary action extracts and stores useful patterns without requiring expensive supervised training, reducing the computational energy needed for subsequent fine-tuning while maintaining model performance.
Solution Approach 2:
The patent extracts useful feature representations from unlabeled data using autoencoders, separating the feature learning task from the final classification task. This extraction allows the system to capture domain-specific patterns without committing the full computational resources needed for complete supervised training, thereby reducing overall energy consumption.
3Measurement precision
If neural networks are trained extensively with balanced training sets, then classification accuracy improves, but the process becomes cumbersome and laborious
Solution Approach 1:
The patent applies preliminary unsupervised pre-training to learn robust feature representations that are invariant to class imbalances. This preliminary action creates a solid foundation that reduces the sensitivity to training set composition, thereby improving classification accuracy without requiring carefully balanced training datasets or complex data preprocessing procedures.
4Productivity
If traditional initialization methods are used, then the neural network can be set up quickly, but energy consumption and computational cycles increase by up to 30%
Solution Approach 1:
The patent performs preliminary unsupervised pre-training that, while requiring some computational resources, establishes optimal weight initializations that dramatically reduce the energy and time needed for subsequent supervised training. The preliminary action of learning domain-specific features creates a more efficient starting point, reducing total energy consumption by up to 30% compared to traditional random initialization followed by extensive training.
Data Source
AI summary
A neural network representing a controlled space can be initialized by collecting state time series data that affects the controlled space such as weather, and also collecting sensor data from the controlled space at the same time. The time series data is used as input to a neural network that models the controlled space until an area in the neural network equivalent to the sensor is at or near the sensor state at a given time.
