Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rules-based approach is used to implement a virtual assistant, then the system structure is simple and easy to understand, but the system lacks flexibility and cannot address queries beyond the scope of predetermined rules
Solution Approach 1:
The patent replaces the mechanical rules-based system with a neural network-based machine learning system. The neural network learns patterns from training data and generates responses without requiring explicit programming of rules, thereby achieving flexibility and adaptability while maintaining manageable complexity through automated learning processes.
Solution Approach 2:
The system dynamically adjusts its response generation parameters based on the input query and learned patterns. The neural network modifies its internal parameters (weights and biases) through training, enabling it to adapt to different query types and generate appropriate responses without changing the overall system structure.
2Adaptability or versatility
If many predetermined rules are coded to govern virtual assistant responses, then the system can handle specific queries effectively, but the system becomes rigid and cannot evolve beyond the finite set of rules
Solution Approach 1:
The neural network performs self-learning through automated training processes. It independently adjusts its internal parameters by processing training data and minimizing loss functions without requiring manual rule creation or system reconfiguration, enabling the system to evolve and adapt to new query patterns autonomously.
Solution Approach 2:
The system performs preliminary learning during a training phase before deployment. By pre-training the neural network on extensive datasets, the system acquires knowledge and patterns in advance, enabling it to handle diverse queries effectively without requiring complex rule sets during operation.
3Reliability
If a rules-based virtual assistant is implemented, then the development and deployment process is straightforward, but the system cannot provide meaningful responses to unrecognized or complex user inputs
Solution Approach 1:
The system performs comprehensive learning during a preliminary training phase using extensive datasets. This pre-training enables the neural network to acquire knowledge for handling diverse and complex queries before deployment, improving reliability without complicating the operational deployment process.
Solution Approach 2:
The training process incorporates feedback mechanisms where the neural network adjusts its parameters based on performance metrics and loss functions. This automated feedback loop enables the system to learn from errors and improve response quality iteratively, maintaining development simplicity while enhancing reliability.
Data Source
AI summary
Systems and methods for implementing an artificially intelligent virtual assistant includes collecting a user query; using a competency classification machine learning model to generate a competency label for the user query; using a slot identification machine learning model to segment the text of the query and label each of the slots of the query; generating a slot value for each of the slots of the query; generating a handler for each of the slot values; and using the slot values to: identify an external data source relevant to the user query, fetch user data from the external data source, and apply one or more operations to the query to generate response data; and using the response data, to generate a response to the user query.
