在医学图像分析领域,神经网络、决策树及基于集成的学习算法在大量数据支持下表现优异,尤其在生殖系统异常检测中。然而,医学图像普遍存在数据量少、置信度低的挑战。本文提出TreeNet,一种专为医学图像分析设计的分层决策集成学习方法。该方法融合神经网络、集成学习与树模型的关键特性,具备强适应性与高可解释性,适用于复杂医疗任务。评估显示,在完整训练数据下F1-score达0.85,使用50%数据时仍保持0.77,仅下降0.08;训练时间大幅缩减。模型推理速度达32帧/秒,满足实时应用需求。综合评估表明,TreeNet在数据稀缺且需实时响应的医学图像分析中具有高效性与实用性。
原文摘要 · Abstract (English)
Within the domain of medical image analysis, three distinct methodologies have demonstrated commendable accuracy: Neural Networks, Decision Trees, and Ensemble-Based Learning Algorithms, particularly in the specialized context of genstro institutional track abnormalities detection. These approaches exhibit efficacy in disease detection scenarios where a substantial volume of data is available. However, the prevalent challenge in medical image analysis pertains to limited data availability and data confidence. This paper introduces TreeNet, a novel layered decision ensemble learning methodology tailored for medical image analysis. Constructed by integrating pivotal features from neural networks, ensemble learning, and tree-based decision models, TreeNet emerges as a potent and adaptable model capable of delivering superior performance across diverse and intricate machine learning tasks. Furthermore, its interpretability and insightful decision-making process enhance its applicability in complex medical scenarios. Evaluation of the proposed approach encompasses key metrics including Accuracy, Precision, Recall, and training and evaluation time. The methodology resulted in an F1-score of up to 0.85 when using the complete training data, with an F1-score of 0.77 when utilizing 50\% of the training data. This shows a reduction of F1-score of 0.08 while in the reduction of 50\% of the training data and training time. The evaluation of the methodology resulted in the 32 Frame per Second which is usable for the realtime applications. This comprehensive assessment underscores the efficiency and usability of TreeNet in the demanding landscape of medical image analysis specially in the realtime analysis.
