Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large language models (LLMs) face challenges in efficiently processing high-dimensional, structured user activity data due to high cardinality and computation costs, making it difficult to discern patterns and generate insights.
Innovation Solution
The use of Ideographic Contrastive Autoencoders (ICAEs) to encode high-dimensional user activity data into compact, fixed-length words, followed by fine-tuning LLMs to learn and perform tasks using this custom lexicographical vocabulary, reducing computation costs and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-dimensional structured user activity data is input directly into the LLM, then the LLM can process the data, but the token space increases significantly driving up computation cost and time
Solution Approach 1:
The patent extracts only the essential patterns and relationships from high-dimensional structured user activity data using an ICAE encoder, converting it into a compact fixed-length word representation. This extraction process removes redundant information while preserving the core meaningful patterns, thereby reducing the token space required for LLM input without losing critical data insights.
Solution Approach 2:
The patent transforms the parameter representation of user activity data by changing it from high-dimensional structured format to a compact fixed-length word format through the ICAE encoder. This parameter transformation maintains the essential information while significantly reducing the dimensionality and token space requirements, enabling efficient LLM processing.

3Quantity of substance
If high-dimensional structured user activity data is input directly into the LLM, then the LLM can process the data, but the high cardinality makes it difficult to discern patterns
Solution Approach 1:
The patent extracts only the essential patterns and relationships from high-dimensional structured user activity data using an ICAE encoder, converting it into a compact fixed-length word representation. This extraction process removes redundant information while preserving the core meaningful patterns, thereby reducing the token space required for LLM input without losing critical data insights.
Solution Approach 2:
The patent segments the high-dimensional structured user activity data into meaningful conceptual units through the ICAE encoder, which learns to group related features together. This segmentation transforms the complex high-cardinality data into a manageable fixed-length word representation that the LLM can process effectively, making pattern recognition feasible.
4Loss of time
If the data is compressed into a compact form, then computation cost and token space are reduced, but the data structure becomes more abstract
Solution Approach 1:
The patent introduces an ICAE encoder as an intermediary component between the structured data source and the LLM. This intermediary learns to map high-dimensional structured data to a compact fixed-length word representation, serving as a bridge that translates complex data structures into a form suitable for efficient LLM processing while preserving essential patterns.
