Solution Overview

Problem

Existing electronic assistants lack the ability to provide contextually relevant responses to user queries and commands, as they do not effectively utilize environmental context information, leading to inefficient and non-tailored interactions.

Innovation Solution

The implementation of hierarchical cascading models that analyze images of the environment to determine context, allowing for the selection and application of more relevant models to parse queries and commands, thereby providing a more tailored response without requiring detailed user input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If hierarchical cascading models are applied to analyze environmental images, then response accuracy and relevance are improved, but computational complexity and processing time increase

Engineering Contradiction:
Improveresponse accuracyVSAvoidcomputational complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The environmental analysis is divided into multiple hierarchical levels. First, a coarse-grained scene classification model identifies the general environment type (e.g., kitchen, bedroom, office). Then, based on the scene type, finer-grained object detection models are selectively applied to identify specific objects relevant to that environment. This segmentation allows the system to achieve high response accuracy without applying all possible models to every image, thereby reducing overall computational complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary scene classification before conducting detailed object analysis. By first determining the general environment type using a lightweight classification model, the system prepares the context in advance, which allows subsequent models to focus only on environment-specific objects and features. This preliminary action improves the efficiency and accuracy of later processing stages.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple hierarchical models are applied to determine environmental context, then response relevance is improved, but processing time increases

Engineering Contradiction:
Improveresponse relevanceVSAvoidprocessing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The processing pipeline is segmented into hierarchical stages where each stage filters and refines the environmental understanding. The first stage quickly identifies the broad scene category, the second stage detects prominent objects, and subsequent stages analyze specific features relevant to the identified context. This segmentation allows the system to achieve high adaptability and response relevance while minimizing processing time by not applying all models uniformly to all images.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies only the necessary level of analysis depth for each query based on the environmental context. For simple scene classification tasks, only the first hierarchical level is activated. For more complex queries requiring object identification, additional hierarchical levels are selectively engaged. This partial action approach ensures response relevance is improved only to the extent needed, avoiding unnecessary processing time consumption.

Inventive Principle:
Principle #16Partial or excessive action

3Ease of operation

If environmental context analysis is performed using hierarchical models, then user interaction quality is improved, but energy consumption increases

Engineering Contradiction:
Improveuser interaction qualityVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The energy-intensive model processing is segmented hierarchically, with low-power scene classification performed first on mobile devices or edge processors. Only when higher-level context is needed do the system transition to more computationally demanding object detection and recognition models, potentially offloading them to cloud-based processors. This segmentation improves user interaction quality while managing energy consumption by applying computational resources only when and where needed.

Inventive Principle:
Principle #1Segmentation

AI summary

Examples disclosed herein relate to determining a response based on hierarchical models. In one implementation, a processor applies a first model to an image of an environment to select a second model. The processor applies the selected second model to the image and creates an environmental description representation based on the output of the second model. The processor determines a response based on the environmental description information.
