Solution Overview

Problem

Current large language models (LLMs) struggle to generate appropriate responses at the right time and to the right user in multi-user conversations, leading to inefficient and disorganized communication.

Innovation Solution

Implementing a framework that utilizes multiple machine learning models to determine when and to whom to generate responses in multi-user conversations, including user input processing and metadata analysis to decide on response generation, with options for users to opt in or out of chat services and encryption of user inputs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If current LLMs are used to respond to user queries in multi-user conversations, then responsive content can be generated, but inappropriate responses or inappropriate timing lead to inefficient and disorganized communications

Engineering Contradiction:
Improveresponse generation efficiencyVSAvoidresponse appropriateness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system segments the response generation process into multiple independent stages: (1) a first ML model processes user input and metadata to determine whether a response is needed and identifies the intended user; (2) a second ML model generates the actual response content only if needed. This segmentation allows each model to specialize in specific tasks, improving both efficiency by avoiding unnecessary processing and reliability by ensuring appropriate response selection before generation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary analysis using the first ML model before invoking the second ML model for response generation. The first model pre-processes user input and metadata to determine response necessity and target user, acting as a gatekeeper that prevents unnecessary or inappropriate responses from being generated, thus improving both efficiency and response appropriateness.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If LLMs process all user inputs to generate responses, then comprehensive coverage is achieved, but computational resources are wasted on inputs that don't require responses

Engineering Contradiction:
Improveinput processing coverageVSAvoidcomputational resource consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system extracts and processes only the essential information from user inputs using the first ML model (determining response necessity and target user) before engaging the computationally intensive second ML model. This extraction approach filters out inputs that don't require responses, significantly reducing overall computational resource consumption while maintaining comprehensive coverage for inputs that do need processing.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system applies partial action by using the first ML model to perform preliminary filtering and classification of user inputs, processing only the critical decision-making aspects rather than generating complete responses for all inputs. This partial processing approach reduces computational burden while ensuring that full response generation is performed only when necessary and appropriate.

Inventive Principle:
Principle #16Partial or excessive action

3Productivity

If user inputs are processed by ML models, then responsive content is generated, but user privacy may be compromised without selective access controls

Engineering Contradiction:
Improveresponse generation capabilityVSAvoiduser privacy risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system implements local quality by providing users with selective control over their input data processing. Users can individually opt in or opt out of having their inputs processed by the ML models. This localized control mechanism respects user privacy preferences while maintaining the productivity benefit of automated response generation for those who consent, eliminating the harmful privacy risk for users who opt out.

Inventive Principle:
Principle #3Local quality

AI summary

Implementations relate to training one or more generative models to determine whether to generate a response responsive to a user input received in a multi-user conversation. For example, a trained generative model can be utilized to process a user input and/or associated metadata, to generate a model output. The user input may be directed to another user in the multi-user conversation. In this case, the model output of the trained generative model that corresponds to the user input can indicate no response for the user input needs to be generated. The user input may alternatively be directed to a virtual assistant representing the application/service that enables the multi-user conversation. In this case, the model output of the trained generative model can be processed to derive a response responsive to the user input. Such response can be rendered and viewed by all users in the multi-user conversation.
