A neural network is a type of computer program that can recognize patterns in data and use that knowledge to determine the best course of action in comparable circumstances. The name “neural network” refers to the fact that they are often composed of several layers of neurons. There is now more interest in this area of study thanks to the invention of neural networks, one of the most significant advancements in computer science. These neural networks are effective tools that are widely used in pattern recognition applications because of their capacity to generalize from examples and learn new patterns. CNN, ANN, and RCNN neural network architectures are some of the most popular ones. We employ RNNs and CNNs as they are more effective at handling sequential data, such as texts and photos. Which CNN, ANN, or RCNN should we choose? Here in this article, we’ll offer a brief outline of each of the distinctions between CNN, ANN, and RCNN before delving into more detail regarding their pros and cons. Also, we are sharing my recommendation and explaining why.
As we probably know one of the most often used models these days is convolutional neural networks (CNN). In this computational model of a neural network, one or more convolutional layers may be combined or completely integrated. It is built on a subset of multilayer perceptron. CNN does not encode an object’s position or orientation.Each layer of an artificial neural network is made up of several perceptrons or inseverable inputs that are processed forward, ANN is also sometimes referred to as a feed-forward neural network. One of the simplest neural network types to comprehend is this one. They transmit information in a single direction, passing it through a number of input nodes before it reaches the output node. The neutralization is explained by the possibility of hidden node levels, which may or may not exist. While the capacity to work with incomplete knowledge, fault tolerance, and having a distributed memory are advantages, there are also drawbacks, including hardware dependencies, unexplained network behavior, and determining the appropriate network layout.
The complexity of recurrent neural networks (RNN) is higher. They keep track of the output from processing nodes and re-incorporate it into the model. This is how the model is claimed to learn to anticipate the outcome of a layer. Each node acts as a memory cell in the RNN model, continuing computation, and operation implementation. When a network predicts incorrectly, it uses self-learning and backpropagation to try again. When it comes to time series prediction, recurrent neural networks (RNNs) have the benefit of long short-term memory, which is the ability to remember every bit of information throughout time. The effective pixel neighbourhood can even be increased by combining recurrent neural networks with convolutional layers. The disadvantages of RNNs include their inability to handle very long sequences when using tanh or relu as activation functions, gradient vanishing and explosion difficulties, and the difficulty of training them.
The information for each of the three networks is provided below.
|Type of Data||Tabular Data, Text Data||Image Data||Sequence data|
|Fixed Length input||Yes||Yes||No|
|Vanishing and Exploding Gradient||Yes||Yes||Yes|
|Performance||Compared to CNN and RNN, ANN is thought to be less effective.||ANN and RNN are thought to be less effective than CNN.||When compared to CNN, RNN has fewer feature compatibility.|
|Application||Facial recognition and Computer vision.||Facial recognition, text digitization, and Natural language processing.||Text-to-speech conversions.|

|Cons||Hardware reliance Network behavior that is not clear.||Large training data are required; object location and orientation should not be encoded.||The gradient disappears and explodes.|
Convolutional layers, which extract features from images, are used by CNNs to perform image recognition tasks. They are a fantastic option for image recognition tasks because they are also fairly effective. For sequential data, such as natural language, CNNs are less effective. ANNs are more versatile neural networks that can be applied to problems involving sequential data as well as image identification. However, because they employ fully connected layers, they perform less effectively than CNNs. A type of neural network known as RCNN combines the advantages of CNNs and ANNs. They can handle sequential data as well as extract features from images. They are less effective, though, because they are more complicated than both CNNs and ANNs. ANNs are more versatile neural networks that can be applied to problems involving sequential data as well as image identification. However, because they employ fully connected layers, they perform less effectively than CNNs. ANNs are more likely to overfit the data and need more training data to learn well. Despite these limitations, ANNs are frequently more accurate than other kinds of neural networks and can be utilized for a range of applications.
A type of neural network known as RCNN combines the advantages of CNNs and ANNs and they can handle sequential data as well as extract features from images. They are less effective, though, as they’re more intricate than both CNNs and ANNs. R-CNN, sometimes known as RCNN, is a sort of machine learning model used for computer vision applications, particularly for object detection. R-CNN stands for Region-Based Convolutional Neural Network. In comparison to CNN, the quicker R-CNN outperformed it in all parameter tests, outperforming it by 6.14% for accuracy, 17.28% higher for precision, and 19.06% for recall value. They can handle sequential data as well as extract features from images. However, they are less effective since they are more complicated than both CNNs and ANNs. What neural network is then the most efficient? It is fairly based on the ongoing project. So recurrent neural networks operate on vector patterns in either the input, output or most frequently, both cases. CNN, on the other hand, has a limited Application Programming Interface (API) as well as a predetermined number of processing stages. So CNN is currently somewhat more potent than RNN and CNN can be layered into exceedingly deep models, for which it has been demonstrated to be highly effective, but RNN has issues with gradient fading and exploding.
CNN’s, however, is not perfect either. A standard CNN can identify an object’s kind but not its position. This is because CNN can only regress one object at a time; hence, interference prevents CNN bounding box regression from performing adequately when numerous objects are present in the same visual field. While an R-CNN (R standing for regional, for object detection) can impair the dominance of a particular object in a certain region by forcing the CNN to concentrate on a single region at a time. So the regions in the R-CNN are shrunk into an equal size after being detected by the selective search technique before being fed into CNN for classification and bounding box regression. Therefore, naming a favorite object is helpful. The best option would probably be a CNN if you needed to process images. An ANN might be the best option when processing consecutive data. An RCNN may be the best option if you need to accomplish both.
