PPT-Training convolutional networks

Last time Linear classifiers on pixels bad need nonlinear classifiers Multilayer perceptrons overparametrized Reduce parameters by local connections and shift invariance gt Convolution. ABSTRACT From the desire to update the maximum road speed data for navigation devices a speed sign recognition and detection system is proposed This system should prevent accidental speeding at roads where the map data is incorrect for example due t RECOGNITION. does size matter?.

Convolution is a common image processing technique that changes the intensities of a pixel to reflect the intensities of the surrounding pixels. A common use of convolution is to create image filters. Convolutions. Reduce parameters. Capture shift-invariance: location of patch in image should not matter. Subsampling. Allows greater invariance to deformations. Allows the capture of large patterns with small filters. person 1. person 2. horse 1. horse 2. R-CNN: Regions with CNN features. Input. image.
