16/11/2017 · LeNet-5, a pioneering 7-level convolutional network by LeCun et al in 1998, that classifies digits, was applied by several banks to recognise hand-written numbers on checks (cheques) digitized in 32×32 pixel greyscale inputimages. The ability to process higher resolution images requires larger and

15/3/2018 · Figure 3 : LeNet-5 Architecture LeNet-5 receives an input image of 32 x 32 x 1 (Greyscale image) and goal was to recognise handwritten digit patterns. It uses 5 x 5 filter and with stride is 1. By applying the above receptive field calculation formula and the output

The architecture was later modified by J. Weng’s method called max-pooling. In 2015, AlexNet was outperformed by Microsoft’s very deep CNN with over 100 layers, which won the ImageNet 2015 contest. Network design AlexNet contained eight layers; the first

CNN Architecture Philosophies Analogous to model design in most of machine learning and to the practice of hand-crafting features, CNNs also involve some degree of skilled hand-crafting. Most of hand-crafting involves the design of the architecture of the network.

Convolutional Neural Networks take advantage of the fact that the input consists of images and they constrain the architecture in a more sensible way. In particular, unlike a regular Neural Network, the layers of a ConvNet have neurons arranged in 3 dimensions: width, height, depth .

Another reason why LeNet is an important architecture is that before it was invented, character recognition had been done mostly by using feature engineering by hand, followed by a machine learning model to learn to classify hand engineered features.
