如图1所示,由CNN接收域(228×228)决定的特征图的单比例尺,可能与小的(如32×32)或大的(如640×640)目标严重不匹配。这降低了目标检测性能。 灵感来自于先前关于图2 (c)的方法优于图2 (b)证据,我们提出一种新的多尺度策略,图2所示(g),这可以被视为深CNN图2 (c)的扩展,但只使用单个输入的规模。它与...

大家好,又见面了,我是你们的朋友全栈君。 一.概述 DCNN(A Convolutional Neural Network for Modelling Sentences)by NalKalchbrenner等,又是文本分类论文的一力作。”准确表达句子的语义是语言理解的核心”,通过学习机器学习和TextCNN,我们可以知道n-gram特征是NLP文本任务和句子表达的一种重要方法。TextCNN通过不同...
A convolutional neural network (CNN) is a category ofmachine learningmodel. Specifically, it is a type ofdeep learningalgorithm that is well suited to analyzing visual data. CNNs are commonly used to process image and video tasks. And, because CNNs are so effective at identifying objects, the...
A convolutional neural network (CNN) is a specific type of artificial neural network that uses perceptrons, a machine learning unit algorithm, for supervised learning, to analyze data. CNNs apply to image processing, natural language processing and other kinds of cognitive tasks. Advertisements A ...
Convolutional Neural Networks with Dynamic k-Max Pooling 我们使用卷积结构对句子建模,该卷积结构将宽卷积层和动态k-max池化层交替使用,网络中,中间层特征图的宽度根据输入句子的长度变化,进而产生的体系结构是动态卷积神经网络,图3表示DCNN,将继续对网络细节进行描述。
Owing to the diversity of pulse-wave morphology, pulse-based diagnosis is difficult, especially pulse-wave-pattern classification (PWPC). A powerful method for PWPC is a convolutional neural network (CNN). It outperforms conventional methods in pattern c

the network is to detect items that might have been recognized as important under a convolutional neural network. These items would likely have been discarded during the convolutional neural network execution process. This type of neural network is also widely used for image analysis or processing....
