The system constructs a hierarchical detection framework: a spatio-temporal feature extraction module via fused temporal convolutional networks (TCN) for sequential pattern mining and convolutional neural networks (CNN) for cross-metric correlation learning; a transfer learning module to enhance generalization; and a deep Q-network (DQN) based central controller that dynamically adjusts detection parameters through reinforcement learning. This architecture integrates with cloud workload schedulers by operating at the VM-level (anomaly detection) and edge-server level (DQN control), minimizing core network overhead. Experiments show that the research method achieves a detection accuracy rate of 99.8% in the benchmark test, with an F1 score of 98.7%, which is significantly superior to the accuracy rate of 96.5% of the single convolutional neural network, 92.3% of the multi-layer perceptron, and 97.8% of Google Net. The transfer training experiments show that the accuracy rate of the untuned model on the new dataset is only 70% to 80%, while the detection accuracy can be stably improved to 98% through the adaptive system driven by the DQN. The system shows low volatility during the dynamic adjustment process. The number of training iterations is reduced by 32.3% to 69.8% compared with the traditional static model, indicating that the research method does not affect the time complexity. Research shows that this framework effectively solves the problem of insufficient adaptability of static models to unknown data in the cloud environment through the collaborative mechanism of spatio-temporal feature extraction and reinforcement learning decision-making, providing intelligent operation and maintenance solutions for fields with high reliability requirements such as finance and healthcare.<\/jats:p>","DOI":"10.13052\/jwe1540-9589.2543","type":"journal-article","created":{"date-parts":[[2026,5,25]],"date-time":"2026-05-25T00:36:17Z","timestamp":1779669377000},"source":"Crossref","is-referenced-by-count":0,"title":["IaaS Cloud Adaptive Anomaly Detection Based on the DQN Algorithm"],"prefix":"10.13052","author":[{"given":"Li","family":"Chen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fan","family":"Gou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"5195","published-online":{"date-parts":[[2026,5,24]]},"container-title":["Journal of Web Engineering"],"original-title":[],"link":[{"URL":"https:\/\/journals.riverpublishers.com\/index.php\/JWE\/article\/download\/26759\/23872","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.riverpublishers.com\/index.php\/JWE\/article\/download\/26759\/23873","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.riverpublishers.com\/index.php\/JWE\/article\/download\/26759\/23872","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,6,7]],"date-time":"2026-06-07T00:37:09Z","timestamp":1780792629000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.riverpublishers.com\/index.php\/JWE\/article\/view\/26759"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,5,24]]},"references-count":0,"URL":"https:\/\/doi.org\/10.13052\/jwe1540-9589.2543","relation":{},"ISSN":["1544-5976","1540-9589"],"issn-type":[{"value":"1544-5976","type":"electronic"},{"value":"1540-9589","type":"print"}],"subject":[],"published":{"date-parts":[[2026,5,24]]}}}
