1Speed
If real-time decision-making is implemented in systems with network connections, then responsiveness to user inputs is improved, but latency caused by poor network connection deteriorates performance
Solution Approach 1:
The system performs preliminary actions by predicting future states and pre-computing responses before actual user inputs occur. The machine learning model anticipates potential user actions and prepares appropriate responses in advance, allowing the system to respond immediately when inputs actually occur, thereby eliminating latency without sacrificing responsiveness.
Solution Approach 2:
The system dynamically adapts its behavior based on network conditions and contextual factors. The machine learning model continuously learns from actual user behavior patterns, adjusting its predictions and responses in real-time. This dynamic adaptation allows the system to optimize responsiveness while compensating for network latency through intelligent prediction and adaptation mechanisms.
2Measurement precision
If decisions are made based on current information, then accuracy is improved, but latency prevents access to up-to-date information
Solution Approach 1:
The system performs preliminary analysis by predicting future states and preparing decisions in advance. The machine learning model forecasts what information will be available and pre-computes optimal decisions based on predicted future states, ensuring that when decisions are executed, they are based on the most accurate and up-to-date information possible, eliminating the trade-off between accuracy and information freshness.
Solution Approach 2:
The system implements continuous feedback loops where actual user behavior and system performance are fed back into the machine learning model. This feedback mechanism allows the model to continuously refine its predictions and improve decision accuracy over time, compensating for any information delays by learning from actual outcomes and adjusting future predictions accordingly.
3Adaptability or versatility
If complex processing is performed to handle latency variations, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system implements self-service by using the device's own machine learning capabilities to automatically adapt to network conditions and optimize performance. The model continuously learns from actual usage patterns and self-adjusts its prediction and response mechanisms, eliminating the need for complex external latency compensation systems while maintaining high adaptability to varying network conditions.
Solution Approach 2:
The system changes key parameters such as prediction time horizons, response thresholds, and learning rates dynamically based on network conditions and device performance. By adjusting these parameters rather than implementing complex structural changes, the system achieves high adaptability to latency variations while keeping the overall processing architecture relatively simple and efficient.
