Convolutional Neural Networks – CNNs, also known as Convolutional Neural Networks, have demonstrated remarkable success in the domains of image analysis, manipulation, and categorization. The application of synchronization techniques based on three key factors, including large data, computing power, expertise in enriched algorithms, and experience, has no bounds and is truly remarkable.
History of CNNs
During the 1980s, the emergence of the Convolutional Neural Network (CNN) was introduced by Yann LeCun, a postdoctoral computer science researcher. The constructed system was designed for the purpose of accurately identifying handwritten numerical symbols.
The neural network’s architecture entailed a simplistic design, consisting of five layers comprising of convolutional layers with a dimensionality of 5×5 and max-pooling operations with a 2×2 size. The convolutional neural network architecture was designated as “LeNet” in honor of its creator, Yann LeCun.
The utilization of Convolutional Neural Networks (CNNs) has been constrained due to multifarious factors including the requirement for copious amounts of training data as well as computational resources. Furthermore, owing to its simplistic design, the software has the capacity to operate solely on images with low resolutions.
How Convolutional Neural Networks Works
The building process of a Convolutional Neural Network (CNN) mainly consists of four essential phases, i.e. convolution, pooling, flattening, and full connection. This discussion provides elaborate explanations for these phases. In academic writing, it is recommended to choose suitable parameters and utilize filters with corresponding strides, along with applying padding as needed.
Apply the convolution process to the provided image and then implement the Rectified Linear Unit (ReLU) activation function on the resulting matrix. The fundamental basis of Convolutional Neural Network (CNN) centers around its core process. If this process is executed improperly, it could lead to the unexpected and sudden end of any potential fulfillment.
As illustrated above, Convolutional Neural Networks utilize layers in their construction. The Convolutional Neural Network (ConvNet) is a series of layers wherein each layer is responsible for altering a volume of activations through a differentiable function. The ConvNet architectures we employ are composed of four primary layer types. This post will not investigates the utilization of convolutional layers, rectified linear units (ReLU), pooling, and fully connected layers in the realm of deep learning.
I get this typical questions all the time “Why do need CNNs as we claim they are same as other Neural network”. To answer this yes we do need specialised neural network when there is need to process image data, given that all other factors in the model remain consistent. To that end, it can be succinctly stated that regular neural networks are not capable of accommodating image data at a sufficient scale. This post is on more of news post to create the excitement about CNNs and what are they doing behind the scene.
The German Traffic Sign Recognition Benchmark
Some time in August 2011, These CNNs networks have amazed and created excitement by wining the German Traffic Sign Recognition competition with 99.46% accuracy (vs. humans at 99.22%). This was the start of the machine getting the power of vision. This constituted the inception of the machine’s acquisition of visual capabilities.
For image processing, the filters scan through the image to pass the feature map which gets generated for each filter. Adding more and more filtering layers along with creating more feature maps generally allows abstracts for creating deeper CNN
