多层感知机(MLP, Multilayer Perceptron)
Fully Connected Layer
时延神经网络(TDNN, Time-Delay Neural Networks)
TDNN是一个常用于语音信号处理领域卷积神经网络,使用 FFT 预处理的语音信号作为输入,其隐含层由2个一维卷积核组成,以提取频率域上的平移不变特征。
卷积神经网络(CNN, Convolutional Neural Networks)
内积 (dot product, scalar product)
Architect
- Convolution
- Pooling
- Flatten
Property
- Some of patterns are much smaller than the whole image
- The smae pattterns appear in different regions
- Subsampling the pixels will not change the object
1 x 1 Convolution
1 x 1 的卷积核用来实现降通道数的操作
