Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-modal conversational AI systems struggle to effectively capture and recognize sequential and temporal attentions in long conversations, necessitating a need for a unified representation model that incorporates both soft and hard attentions.
Innovation Solution
A system and method for processing multi-modal conversations using a sequential-temporal encoder-decoder model that extracts entities, determines semantic relationships, and generates responses based on attentions, employing a multilevel encoder-decoder architecture with horizontal and vertical bi-directional attention flows to analyze candidate responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If uni-modal application architectures are used for question answering in long conversations, then the system structure is simple, but the system is inefficient to capture and recognize sequential and temporal attentions
Solution Approach 1:
The system segments the conversation processing into multiple modalities (text, audio, video) with dedicated processing streams, allowing each modality to be handled by specialized components while maintaining overall system efficiency in capturing temporal attentions
Solution Approach 2:
The patent introduces a temporal dimension to the encoder-decoder architecture by implementing sequential processing stages that analyze conversations over time, adding time as a new dimension for attention analysis beyond traditional single-turn processing
2Measurement precision
If a sequential-temporal encoder-decoder model is implemented for attention analysis, then the attention analysis capability is improved, but the model complexity increases
Solution Approach 1:
The model segments attention mechanisms into distinct hard attention and soft attention components, each handling different aspects of temporal and sequential analysis, which improves precision while managing complexity through modular design
Solution Approach 2:
The patent introduces intermediate representation layers that transform multi-modal inputs into unified semantic representations, serving as mediators between raw inputs and final attention analysis, thereby improving precision without proportionally increasing overall model complexity
3Reliability
If unified representations learned based on soft and hard attentions are implemented, then the conversational understanding is improved, but the computational requirements increase
Solution Approach 1:
The system applies partial attention mechanisms by selectively focusing computational resources on relevant conversation segments and modalities rather than processing all inputs uniformly, improving understanding reliability while reducing overall computational energy consumption
Solution Approach 2:
The model employs periodic attention updates where soft and hard attentions are computed at specific intervals rather than continuously, maintaining reliable conversational understanding while significantly reducing computational energy requirements through time-efficient processing

AI summary
Methods and systems for processing a multi-modal conversation are disclosed. A multi-modality input is selected from a plurality of multimodality conversations among two or more users. The system annotates the first modality inputs and at least one attention region in the first modality input corresponding to a set of entities and semantic relationships in a unified modality is identified by a discrete aspect of information bounded by the attention elements. The system models the representations of the multimodality inputs at different levels of granularity, which includes entity level, turn level, conversational level. The method proposed uses a network that consists of multilevel encoder-decoder architecture that is used to determine unified focalized attention, analyze and construct one or more responses for one or more turns in a conversation.
