揭示生物智能的基本神经关联、构建数学模型并开展计算模拟,对推动人工智能新范式至关重要。本研究采用神经动力学建模方法,构建了一个涵盖从视觉输入到行为输出的完整视觉决策模型。该模型受灵长类动物背侧视觉通路关键组件启发,不仅与人类行为高度吻合,还反映了灵长类动物的神经活动,其准确率可与卷积神经网络(CNNs)相媲美。此外,磁共振成像(MRI)识别出与感知决策任务表现相关的神经影像特征,如结构连接和功能连接。我们提出一种神经影像引导的微调方法并应用于模型,性能提升与个体间行为差异同步。相较于经典深度学习模型,本模型更准确地复现生物智能的行为表现,依赖生物神经网络的结构特性而非海量训练数据,在扰动下也表现出更强的鲁棒性。

原文摘要 · Abstract (English)

Uncovering the fundamental neural correlates of biological intelligence, developing mathematical models, and conducting computational simulations are critical for advancing new paradigms in artificial intelligence (AI). In this study, we implemented a comprehensive visual decision-making model that spans from visual input to behavioral output, using a neural dynamics modeling approach. Drawing inspiration from the key components of the dorsal visual pathway in primates, our model not only aligns closely with human behavior but also reflects neural activities in primates, and achieving accuracy comparable to convolutional neural networks (CNNs). Moreover, magnetic resonance imaging (MRI) identified key neuroimaging features such as structural connections and functional connectivity that are associated with performance in perceptual decision-making tasks. A neuroimaging-informed fine-tuning approach was introduced and applied to the model, leading to performance improvements that paralleled the behavioral variations observed among subjects. Compared to classical deep learning models, our model more accurately replicates the behavioral performance of biological intelligence, relying on the structural characteristics of biological neural networks rather than extensive training data, and demonstrating enhanced resilience to perturbation.
