Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Deep Learning and Probabilistic models for Natural Language Processing struggle with efficiently generating accurate source code, often resulting in computationally intensive solutions with grammatical and syntactical inconsistencies, which can be time-consuming and error-prone, especially for complex software systems.
Innovation Solution
A dual Bayesian Encoder-Decoder model approach that merges statistical criteria from two sequences of Probabilistic Distributions to reduce Text to Code transformation time and increase accuracy, using confidence metrics like Uncertainty and Certainty to improve code generation, with separate models for Text to AST and Text to Code transformations.

Engineering Contradiction Analysis
1Productivity
If Deep Learning and Probabilistic models are used to automate source code generation, then productivity is improved, but manufacturing precision deteriorates due to grammatical and syntactical inconsistencies
Solution Approach 1:
The patent introduces an Abstract Syntax Tree (AST) as an intermediary representation between natural language input and source code output. The dual Bayesian Encoder-Decoder models first transform natural language to AST tokens, then transform AST tokens to source code tokens. This intermediate AST representation serves as a structured bridge that maintains grammatical correctness while enabling automated generation, resolving the contradiction between speed and accuracy by providing a formal grammar-based intermediate stage.
Solution Approach 2:
The patent segments the code generation process into two distinct transformation stages: (1) Natural Language to AST tokens, and (2) AST tokens to Source Code tokens. Each stage has its own specialized Bayesian Encoder-Decoder model. This segmentation allows each model to focus on specific aspects of the transformation, improving overall precision while maintaining productivity through specialized optimization at each stage.
2Ease of operation
If Deep Learning models are used for text to code transformation, then ease of operation is improved, but device complexity increases due to computationally intensive processing
Solution Approach 1:
The patent extracts and leverages pre-existing formal grammar structures and AST representations from compiler theory, rather than learning grammar rules from scratch through computationally intensive Deep Learning. By taking out and utilizing established linguistic frameworks and syntax tree structures, the system reduces computational complexity while maintaining ease of operation through automated transformation pipelines.
Solution Approach 2:
The system performs preliminary action by pre-defining the AST token vocabulary and grammar structures before the transformation process begins. The Bayesian models are trained on pre-processed data with established AST representations, allowing the system to operate with reduced computational complexity during inference while maintaining high automation capability.
3Manufacturing precision
If Bayesian Encoder-Decoder models are used with confidence metrics, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The Bayesian Encoder-Decoder models perform self-service by generating their own confidence metrics (certainty and uncertainty values) during the transformation process. These self-generated confidence scores are then used by the system to automatically determine when to apply deterministic grammar rules versus when to rely on probabilistic predictions. This self-service mechanism improves precision without requiring external validation systems, as the models provide their own quality assessment.
Solution Approach 2:
The system implements feedback loops where confidence metrics from the Bayesian models feed into deterministic rule application decisions. When confidence is low, the system applies deterministic grammar rules to correct potential errors; when confidence is high, it accepts the probabilistic prediction. This feedback mechanism improves manufacturing precision by dynamically adjusting processing based on model confidence, while the feedback is integrated seamlessly into the existing pipeline without adding significant complexity.
Data Source
AI summary
Methods, apparatus, and software for implementing dual Bayesian encoding-decoding for text-to-code transformations. In one aspect, a multi-model probabilistic source code model employing dual Bayesian encoder-decoder models is used to convert natural language (NL) inputs (aka requests) into source code. An NL input is processed to generate a Probabilistic Distribution (PD) of Source code (SC) tokens in an SC token sequence and a PD of Abstract Syntax Tree (AST) tokens in an AST token sequence, wherein each SC token is associated with a respective AST token, and each of the SC and AST tokens have a respective PD. One or more fixing rules are applied to one or more tokens SC tokens that are identified as needing fixing, wherein the fixing rule are selected in consideration of the PDs of the SC tokens and the PDs of their associated AST tokens.
