摘要:

昆虫视觉支持包括关联学习、导航和物体检测在内的复杂行为,长期以来激励了计算模型以理解生物视觉处理。然而,许多现代模型优先考虑任务性能而忽视了生物基础的处理路径。在此,我们介绍了一种生物启发的视觉模型,该模型捕捉了昆虫视觉系统的原理,将密集的视觉输入转换为稀疏、判别性的代码。该模型使用完全自监督的对比目标进行训练,使表示学习无需标注数据,并支持在不同任务中无需依赖领域特定分类器的重用。我们评估了所得到的表示在花卉识别任务和自然图像基准上的表现。该模型始终产生可靠的稀疏代码,能够区分视觉上相似的输入。为了支持不同的建模和部署用途,我们已经将该模型实现了人工神经网络和脉冲神经网络两种形式。在模拟定位设置中,我们的方法优于简单的图像下采样比较基线,突显了将神经形态视觉处理路径纳入其中的功能优势。总体而言,这些结果通过提供一个可推广的生物启发视觉模型,推动了昆虫计算建模,该模型能够在多样化的任务中实现稀疏计算。

英文摘要:

Insect vision supports complex behaviors including associative learning, navigation, and object detection, and has long motivated computational models for understanding biological visual processing. However, many contemporary models prioritize task performance while neglecting biologically grounded processing pathways. Here, we introduce a bio-inspired vision model that captures principles of the insect visual system to transform dense visual input into sparse, discriminative codes. The model is trained using a fully self-supervised contrastive objective, enabling representation learning without labeled data and supporting reuse across tasks without reliance on domain-specific classifiers. We evaluated the resulting representations on flower recognition tasks and natural image benchmarks. The model consistently produced reliable sparse codes that distinguish visually similar inputs. To support different modelling and deployment uses, we have implemented the model as both an artificial neural network and a spiking neural network. In a simulated localization setting, our approach outperformed a simple image downsampling comparison baseline, highlighting the functional benefit of incorporating neuromorphic visual processing pathways. Collectively, these results advance insect computational modelling by providing a generalizable bio-inspired vision model capable of sparse computation across diverse tasks.
