modular neural network applications

Modular Neural Networks An artificial neural network (ANN) is a collection of parallel distributed information processors or nodes, capable of storing system knowledge and making it available for use. This paper surveys the different motivations for creating MNNs: biological, psychological, hardware, and computational. Artificial Neural Networks are widely used in images and videos currently. Adaptive MNN for character recognitions 3. 6. Modular Neural Networks are use of a number of Neural Networks for problem solving. In the vision example, the brain evolved (rather than learned) to create the LGN. We present a class of efficient models called MobileNets for mobile and embedded vision applications. 1. Multilayer neural networks such as Backpropagation neural networks. The different networks do not really interact with or signal … Modular Neural Network This ANN type combines different neural networks that perform a number of tasks and sub-tasks. Feedforward Neural Network – Artificial Neuron. Organized in a modular format that lets you find and use the information you need fast, the book includes five full chapters that zero-in on specific neural network applications. This type of network is a popular choice for pattern recognition applications, such as speech recognition and handwriting solutions. Figure 2 visualizes the above clustering process for a simple feed-forward neural network composed of 6 modular layers with K= 1 modules being selected at each layer out of a possible M = 3 modules. of modular networks and a fully connected feed forward net- work are presented for comparison purposes, followed by some concluding remarks. Similarly, creating a super-net that combines a large number of existing nets into a super-architecture has been In a modular neural network, all the subnetworks it contains work independently of each other to achieve the output. Now-a-days artificial neural networks are also widely used in biometrics like face recognition or signature verification. Modular Neural Network. Artificial Neural Network Software are intended for practical applications of artificial neural networks with the primary focus is on data mining and forecasting. A survey of typical modular neural networks shows that large-scale nonlinear problems can alleviate its dimensionality curse with modular technique. [1] Some tasks are intractably large for a single neural network. 2.1. Neural Networks find extensive applications in areas where traditional computers don’t fare too well. The borrowed pre-trained model has been integrated into mobile applications that define objects on the screen of the device. As artificial neural network research progresses, it is appropriate that artificial neural networks continue to draw on their biological inspiration and emulate the segmentation and modularization found in the brain. Modular neural networks reduce a single large, unwieldy neural network to smaller, potentially more manageable components. Modular/Multiple Neural networks (MNNs) revolve around training smaller, independent networks that can feed into each other or another higher network. Splitting a neural network and using bottom layers (encoder) with a different set of top layers is a widely-used practice [8]. Here the various neural networks behave as modules to solve a part of the problem. The advantage of this modular neural network is that it breaks down a large and complex computational process into smaller components, thus decreasing its complexity while still obtaining the required output. Similarly, neocognitron also has several hidden layers and its training is done layer by layer for such kind of applications. The intermediary only accepts the modules' outputs—it does no… He was the Santa Clara Chapter Chairman of IEEE Control System Society in 1994.

He is currently a Professor of Computer Science at San Jose State University, CA. We introduce two simple global hyper-parameters that efficiently trade off between latency and accuracy. Business Applications of Neural Networks: Real-world business applications for neural networks are booming. As well, the modules do not interact with each other. The quality of the result will be a function of the quality of the design. The intended audience is researchers and graduate students in the fields of neural networks, computer science, statistical pattern recognition, statistics, control theory and econometrics. The modular approach also takes into account growing network complexity, reducing the difficulty of such inevitable problems as scaling and convergence. However, the high cost associated with ASIC hardware design makes it challenging to build custom accelerators for different targets. Recurrent neural networks handle this stage as it requires the analysis of the sequences of the data points. 2.

By compartmentalizing subtasks, failure and interference are much more readily diagnosed and their effects on other sub-networks are eliminated as each one is independent of the other. Learn how and when to remove this template message, "Biologically Inspired Modular Neural Networks. [2] Within a part of the brain, called the thalamus, lies the lateral geniculate nucleus (LGN), which is divided into layers that separately process color and contrast: both major components of vision. This is one of the simplest types of artificial … Overview of modular neural networks based on how the problem is modularized through various decomposition and subsequent aggregation is given. A scalable modular neural network array architecture has been proposed for real time damage detection in plate like structures for structural health monitoring applications. As compared with the non-modular approach, the modular approach offers comparable prediction performance with significantly lower overall computation time. Convolutional Neural Networks uncover and describe the hidden data in an accessible manner. His current interests include fuzzy logic, soft computing, and semantic web. [3] After the LGN processes each component in parallel, it passes the result to another region to compile the results. Networks with high modularity have dense connections between the nodes within modules but sparse connections between nodes in different modules. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Compression of high level input data A modular neural network has a number of different networks that function independently and perform sub-tasks. This means the training algorithm and the training data can be implemented more quickly. Modular design is one promising approach and has been used in neural network learning to decrease the computation cost and avoid local minima that are common in large neural networks , , , . The intermediary only accepts the modules' outputs—it does not respond to, nor otherwise signal, the modules. His industrial experience includes Senior Consultant in Hong Kong Productivity Council and Vice President in Voxa, Inc., CA. H. Chris Tseng (M’83, SM’90) received the B.S. Each module can be trained independently and more precisely master its simpler task. Conclusion. His current interests include machine learning systems, natural language processing, and web intelligence. In other cases, other models may be superior. He has held regular and visiting positions at Duke University, Santa Clara University, and Chang Gung University in Taiwan. 5. The benefits of modular neural networks include: The possible neuron (node) connections increase quadratically as nodes are added to a network. Regardless of whether a large neural network is biological or artificial, it remains largely susceptible to interference at and failure in any one of its nodes. To lower design cost, we propose MAGNet, a modular accelerator generator for neural networks. A large neural network attempting to model multiple parameters can suffer from interference as new data can alter existing connections or just serve to confuse. Radial basis function Neural Network: Radial basic functions consider the distance of a point … Modular neural networks can allow for sophisticated use of more basic neural network systems managed and handled in conjunction. A modular neural network is an artificial neural networkcharacterized by a series of independent neural networks moderated by some intermediary. By continuing you agree to the use of cookies. Modular and hierarchical neural networks Deep neural nets are both hierarchical and highly modular. [1] The intermediary takes the outputs of each module and processes them to produce the output of the network as a whole. A Modular Neural Network (MNN) is a Neural Net-work (NN) that consists of several modules, each module carrying out one sub-task of the NN’s global task, and all modules functionally integrated. The task is image classification, see Section 3.3. However, it is not clear whether some intermediary ties these separate processes together. Artificial Neural Network Software is used to simulate, research, develop, and apply artificial neural networks, software concepts adapted from biological neural networks. The intermediary takes the outputs of each module and processes them to produce the output of the network as a whole. Assigning specific subtasks to individual modules reduce the number of necessary connections. Overview of modular neural networks based on how the problem is modularized through various decomposition and subsequent aggregation is given. Modular Neural Networks (MNNs) is a rapidly growing field in artificial Neural Networks (NNs) research. The basic idea is to independently develop several "subnetworks" (modules), which may perform the same or re­ lated tasks, and then use an "appropriate" method for combining the outputs of the subnetworks. We present a class of efficient models called MobileNets for mobile and embedded vision applications. Radial basis function Neural Network. Here are some neural network innovators who are changing the business landscape. The subject of this book is predictive modular neural networks and their ap plication to time series problems: classification, prediction and identification. These hyper … Unlike its feedforward cousin, the recurrent neural network allows data to flow bi-directionally. In this thesis we present both a novel neurla network paradigm and an approach for solving sensing and control tasks for mobile robots using this neural network paradigm. Image and video labeling are also the applications of neural networks. Modular Learning in Neural Networks' modular approach is also fully in step with important psychological and neurobiological research. By decomposing the given pattern profiling problem into smaller modules, it is shown that comparable performance can be achieved with improvement on computation and design complexity. Computation time depends on the number of nodes and their connections, any increase has drastic consequences for processing time. Modularity is one measure of the structure of networks or graphs.It was designed to measure the strength of division of a network into modules (also called groups, clusters or communities). A survey of typical modular neural networks shows that large-scale nonlinear problems can alleviate its dimensionality curse with modular technique. In a way, these neural networks are similar to the systems of biological neurons. After this hypothetical insight, I will return to the description of my experiment on the implementation of neural networks in mobile applications. Real world tasks have driven the evolution of this methodology and its components, and we apply our methodology successfully to two robotic applications. we conclude that for 1. The network’s global task can be any neural network application, degree in Electrical Engineering from National Taiwan University in 1982, the PhD degree in Electrical Engineering from University of Illinois at Urbana-Champaign, in 1988. There are several neural network architectures with different features, suited best for particular applications. This study validates that modular design is a promising solution for large-scale soft computing problems. A pattern recognition problem for aircraft trajectory prediction using NeuroFuzzy learning with a two stage modular learning design is presented. A module can be a sub-structure or a learning sub-procedure of the whole network. He was a David Packard Fellow in Santa Clara University during 1988–1990. We study the feasibility and the performance of modular design concept as applied to pattern profiling problems using artificial neural network. A modular neural network is one that is composed of more than one neural network model connected by some intermediary. Even in its most basic applications, it is impressive how much is possible with the help of a neural network. Unlike a single large network that can be assigned to arbitrary tasks, each module in a modular network must be assigned a specific task and connected to other modules in specific ways by a designer. degrees in Computer Science from University of California, San Diego, in 2005 and San Jose State University in (2008), respectively. Each node in the graph represents a Rather, as the tasks grow more abstract, the modules communicate with each other, unlike the modular neural network model. Like, for problem statements where instead of programmed outputs, you’d like the system to learn, adapt, and change the results in sync with the data you’re throwing at it. A modular neural network is an artificial neural network characterized by a series of independent neural networks moderated by some intermediary. The modular neural network gave an accuracy of 95.75% over training data and 98.22% over testing accuracy, which was experimentally determined to be better than monolithic neural networks. We introduce two simple global hyper-parameters that efficiently trade off between latency and accuracy. Neocognitron; Though back-propagation neural networks have several hidden layers, the pattern of connection from one layer to the next is localized. Recurrent Neural Network. He was the organizing chair of International Symposium on Web Intelligence and Security in 2005 and Eighth International Conference on Natural Computing in 2007. Each independent neural network serves as a module and operates on separate inputs to accomplish some subtask of the task the network hopes to perform. The brain, for example, divides the complex task of visual perception into many subtasks. Deep learning is an important part of machine learning, and the deep learning algorithms are based on neural networks. Each independent neural network serves as a module and operates on separate inputs to accomplish some subtask of the task the network hopes to perform. Some tasks that the brain handles, like vision, employ a hierarchy of sub-networks. Modular neural networks come by many other names, for instance multiple models, local models and mixtures of experts. Bassam Almogahed received the B.S and M.S.
