Optimization method of deep time series prediction model based on meta-heuristic RIME algorithm
Time series prediction was recognized as having significant application value in critical fields such as finance
power
and networks. Deep learning models were demonstrated to possess strong fitting capabilities for this task
but their performance was found to be heavily dependent on structural design and hyperparameter selection. Traditional parameter-tuning methods
such as grid search and manual experience
were criticized for their low efficiency and tendency to fall into local optima. To address these issues
a deep time series prediction model based on the BiTCN-BiGRU-Attention architecture was constructed
and a novel metaheuristic optimization algorithm
RIME
was introduced for optimization. The RIME was designed to simulate the natural growth mechanism of rime ice
combining soft rime search strategies
hard rime piercing mechanisms
and positive greedy selection strategies to achieve an effective balance between global exploration and local exploitation. In the experimental section
the algorithm’s performance was comprehensively evaluated on standard benchmark functions and multiple real-world datasets. The results show that the RIME-optimized prediction model was superior to the unoptimized model in terms of accuracy
convergence speed
and stability. New insights and practical pathways were provided for the efficient and automated optimization of deep time series prediction models.
