卷积神经网络(Convolutional Neural Network,简称CNN)是一种深度学习模型,广泛应用于图像识别、计算机视觉和模式识别等领域。它的设计灵感来自于生物学中视觉皮层的工作原理。 卷积神经网络通过多个卷积层、池化层和全连接层组成。 卷积层主要用于提取图像的局部特征,通过卷积操作和激活函数的处理,可以学习到图像的特征表示。 池化层则用于降低

Chunk-Max Pooling很明显也是保留了多个局部Max特征值的相对顺序信息,尽管并没有保留绝对位置信息,但是因为是先划分Chunk再分别取Max值的,所以保留了比较粗粒度的模糊的位置信息;当然,如果多次出现强特征,则也可以捕获特征强度。 Event Extraction via Dynamic Multi-Pooling Convolutional Neural Networks这篇论文提出的是...
