Deep Multi-Module Based Language Priors Mitigation Model for Visual Question Answering

The original intention of visual question answering(VQA) models is to infer the answer based on the relevant information of the question text in the visual image, but many VQA models often yield answers that are biased by some prior knowledge, especially the language priors. This paper proposes a mitigation model called language priors mitigation-VQA(LPM-VQA) for the language priors problem in VQA model, which divides language priors into positive and negative language priors. Different network ...

A Network Model on the Processing of Sound Wave

On the base of auditory neural system, the network model on the processing of the sound wave is presented. The mathematic equation of the network is also discussed. In the network model, in addition to the negative feedback of the neural cell in the output layer, the cell in the input layer excites the corresponding cell in the ontput layer meanwhile it inhibits the lateral cells. The network has its advantage on the processing of sound wave. In addition to filter the noise, it can search the significance frequency segments （Barks）. The ＂channel suppresser＂ feature, the special phenomena of the human ear, is explained based on the model. The learning algorithm of the network model is discussed, too. In the end, an example is introduced about the application of the network.     

三亚六道湾海洋生态现状调查与初步研究

通过对2001年12月海南三亚六道湾近岸海域水生生物群落定性定量调查,初步比较分析了水生生物群落与水富营养化状态指数的相互关系,并借以对该区域水环境质量进行评价.结果表明:受该区域海水营养盐浓度较低影响,海水水质及底质质量优良;与海南其他地区比较,海洋生物生物量和栖息密度较低;底栖动物存在明显的群落结构特征.     

南方湖库初春"水华"现象原因分析与对策

根据2004年3月海南省万泉河上游牛路岭水库"水华"事件调查监测结果,对此次"水华"现象发生原因进行了初步分析,并相应提出了防止"水华"现象再次发生的预防控制对策,对南方湖库初春"水华"现象控制有一定的借鉴作用.
