CAUSAL DISCOVERY AND MISSING VALUE IMPUTATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18579451 titled 'CAUSAL DISCOVERY AND MISSING VALUE IMPUTATION
The abstract describes a computer-implemented method that involves encoding input vector values into latent vectors using a neural network, determining an output vector using a second neural network with a graph neural network, and minimizing a loss function by tuning parameters of the neural networks and edge probabilities of the graph.
- Input vector values are encoded into latent vectors using a first neural network.
- The latent vectors are input into a second neural network with a graph neural network to determine an output vector.
- The edge probabilities of the graph, parameters of the neural networks, and loss function are minimized to optimize the system.
- The loss function includes a measure of difference between the input vector and the output vector, as well as a function of the graph.
Potential Applications: - Predictive modeling - Data analysis - Pattern recognition
Problems Solved: - Efficient encoding and decoding of input vectors - Optimization of neural network parameters and graph edge probabilities
Benefits: - Improved accuracy in predicting output vectors - Enhanced understanding of causal relationships between variables - Efficient data processing and analysis
