1Productivity
If traditional path selection methods are used in multi-media multi-path networks, then the system structure remains simple, but resource utilization efficiency deteriorates and service quality varies greatly
Solution Approach 1:
The system employs reinforcement learning algorithms that enable the network to automatically learn and optimize path selection strategies without manual intervention. The algorithm continuously adapts to network conditions and autonomously makes decisions about resource allocation and path routing, allowing the system to self-improve resource utilization efficiency while managing its own complexity
Solution Approach 2:
The invention transforms the path selection problem by changing the parameters used for decision-making. Instead of using simple static criteria, the system uses state information representing network conditions and learns optimal actions through reinforcement learning. This parameter transformation enables efficient resource utilization by considering multiple dynamic factors in path selection
2Reliability
If path selection is not optimized, then the system operation remains simple, but service quality and user experience deteriorate
Solution Approach 1:
The reinforcement learning implementation includes feedback mechanisms where the system continuously monitors network performance and user experience metrics. This feedback is used to update the Q-table and improve future path selection decisions, ensuring high service quality while managing complexity through iterative learning rather than complex predetermined rules
Solution Approach 2:
The system performs preliminary learning and builds a Q-table in advance to prepare for optimal path selection. By pre-learning network patterns and storing learned knowledge in the Q-table, the system can quickly make reliable path selection decisions without complex real-time computations, thus ensuring service quality while controlling operational complexity
3Productivity
If reinforcement learning is applied without pre/post-processing, then the algorithm remains simple, but learning effectiveness and resource efficiency deteriorate
Solution Approach 1:
The system performs pre-processing of state information before feeding it to the reinforcement learning algorithm. This preliminary processing organizes and prepares the input data in an optimized format, enabling the learning algorithm to process information more efficiently and converge faster, thus improving learning efficiency while managing processing complexity through structured preparation
Solution Approach 2:
The processing pipeline is segmented into distinct stages: pre-processing of state information, application of reinforcement learning algorithm, and post-processing of results. This segmentation allows each component to be optimized independently, improving overall learning efficiency while making the complexity manageable through modular processing steps
