基于人脑多种思维系统协同工作原理提出了语用协同模型.该模型利用语用信息描述系统运动状态,实现了拟形象思维系统和拟逻辑思维系统协同工作,具有较好的模式分类和容错能力.同时,利用序列背景建模任务检验了语用协同模型.经实验验证,基于语用协同模型的背景建模方法能建立有效的背景描述,对典型干扰具有鲁棒性,获得了良好的背景建模效果. A pragmatic collaborative model is proposed based on the collaborative working principle of many kinds of thinking systems in the human brain. The model uses pragmatic information to describe the movement of the system and achieves the coordination of the quasi-image thinking system and the quasi-logical thinking system with good pattern classification and fault tolerance Ability.At the same time, we verify the pragmatic collaborative model by using the sequence background modeling task.After the experimental verification, the background modeling method based on the pragmatic collaborative model can establish an effective background description, is robust to typical interference, and obtains a good Background modeling effect.
