To be very clear, I am not a fan of this book.
Even for a person who has some experience in Deep learning, the way the information has been was not very reader-friendly. Not really recommended. There are better options available.
Well how do you say about it Let's say there are 3 types of books 1.
It is not for beginners but if you have a good knowledge of mathematics and statistics you can milk almost everything from this book. This book is superb. I have read Bishop's book also on neural networks, but this book by far provides the best possible exposition to the field.
The best part is that the author does not sacrifice mathematical rigour to make the material easier. The writing is so lucid that the reader does not stumble at the notations or exposition anywhere. Also, the initial exposition at the beginning of every chapter makes sure that the reader doesn't get numbed by jargon and math in the beginning, rather gets curious about what all the chapter has to offer.
If you are serious about understanding all the nuances, both theoretical and applied start reading this book. It's good if you are studying neural networks for the first time.
It has really good examples and covers almost everything in the field of neural networks, and provides lots of references. Topics are covered but too complicated language. Different symbology than standard. Good book and prompt service. This book is really a good one for a begginer to understand the inside of NN. I think more analogies could have been given.

Neural Networks: A Classroom Approach
In addition, Williams includes a philosophical discussion of possible approaches to using neural networks for control, taking care to tie these concepts to those introduced by Barto in chapter 1 as well as to concepts from traditional control theory.
Williams particularly emphasizes what he terms a radical approach within which connectionist models are used to model systems whose state cannot be determined by a fixed set of finitely many past values of its input and output. According to Williams, the radical approach has no natural counterpart in the realm of adaptive linear filters; recurrent networks, however, are well-suited to model such systems.
This approach thus provides the largest potential for novel contribution by neural network methods.
In chapter 5, Kumpati Narendra directly addresses the major theme of this book; namely, he investigates the use of well-understood adaptive control techniques for studying neural network control schemes. Narendra describes in greater detail some of the supervised learning schemes introduced F.
Guenther and D. Bullock by Barto, focusing on the use of back propagation networks as natural substitutes for the adaptive components already found within standard adaptive control systems.
In summary, Narendra makes an assertion consistent with the views of several other authors in this book: a well-developed theory of control using neural networks will require solution of many outstanding problems such as system stability, but current simulation results indicating the effectiveness of such systems on difficult control problems provides ample justification for continued study of these problems. One of the few chapters actually comparing a neural network to standard adaptive alternatives is chapter 6 by Gordon Kraft III and David Campagna.
The authors conclude that the CMAC compares favorably on three criteria: nonrestriction to linear systems, noise rejection, and implementation speed for real-time control. However, it compared unfavorably on convergence rate, presumably because the adaptive task for both other controllers was restricted to estimating the values of parameters in a pre-existing model.
David E Shanno provides oft-overlooked alternatives to the steepest descent methods typically used to train neural networks in chapter 7. Included are Newton, quasi-Newton, and conjugate gradient methods for parameter estimation in large-scale optimization problems.
Pointers are given to more complete treatments of these methods in the numerical algorithms literature.
Although cheap and easy to implement, steepest descent methods can suffer from extremely slow convergence. These alternatives can provide much faster convergence with varying computational and memory requirements.
Convergence time surfaces as an important theme once again in chapter 8, the final chapter in the general principles section of the book. Here Richard Sutton constructs a simple adaptive path planner to illustrate the large benefits that can accrue when what the early cognitive psychologist Tolman called "vicarious trial and error" is combined with a reinforcement learning rule suitable for temporal credit assignment.
Like the adaptive critic approach described by Werbos in chapter 3, this planner, called Dyna, is based on dynamic programming principles from control theory. Sutton describes results of a study which shows that a system able to "perform" trial and error actions both in the world and in imagination with the aid of an internalized world model converges much more quickly to an optimal policy than a system restricted to performance in the world.
Because this chapter is intended to present general neural network control principles, it is unfortunate that primary emphasis is on a particular planning model with too little discussion of possible implications and applications of the ideas inherent to this model for neural network control. In chapter 9 Mitsuo Kawato initiates the section on motion planning with a survey that encompasses both inverse kinematics and inverse dynamics, but with an emphasis on the latter.
Kawato is well-known for his work on combining feedback controllers with adaptive feedforward controllers that are trained by the error signals arising within the feedback controller. Though he has explored a wide range of network Book Review designs, an enduring aspect of his approach since at least is based on the hypothesis that in the brain the cerebellum is an error-trained feedforward controller. An idea pursued in the work of Kawato and others e. Instead, one can simply input the desired kinematics to both a low-gain feedback controller and an initially low-gain feedforward controller, and use the error signals from the feedback controller to slowly increment gains through the sidepath-feedforward controller.
Eventually, the feedback controller is largely "unloaded" because the predictable component of its work load has been taken over by the feedforward controller, which has learned the inverse dynamics i. Designs for this kind of autonomous supersession of control allow a system to be robust in nonstationary environments. The robustness derives from the existence of a fallback mode e.
In the current work, Kawato addresses the ill-posedness i. Different models for learning inverse dynamics are discussed with emphasis on their ability to cope with this ill-posedness. In chapter 10, Bartlett Mel continues the theme of vicarious trial and error raised in Sutton's contribution. He explores a system in which the primary mapping learned from experience and applied during performance is a forward kinematics mapping from initial states and unit joint angle perturbations to implied motions of a robot arm.
His robotic system uses this learned map to "mentally" search for an arm trajectory capable of bridging the gap between an initial and a desired endpoint position without having any part of the arm collide with obstacles. This task is simplified relative to standard techniques by eschewing all explicit geometric computations and relying on iterative use of the learned map to generate a visual representation of the expected 2-D area displaced by the arm following a candidate vector of unit joint rotations.
This visual representation arises within the same visual representation field used to register the positions of obstacles, so an expected collision is specified by overlap of imagined arm and actual object. Mel argues that because explicit geometric modeling is so compute-intensive, replacement of classical geometric modeling by a neural map might yield a large performance gain.
Mel's method of sensory-based motion planning which trades optimality for ease of computation represents an approach to neural network control which is radically different from any other in the book. In chapter 11, Christopher Atkeson and David Reinkensmeyer discuss the use of associative content-addressable memories ACAMs in a simple control scheme which stores "experiences" in a memory, then uses a parallel search during performance to find the stored experience which best matches current needs.
Although simpler than the CMAC, this system sacrifices the CMAC property of automatic generalization arising from continuity and overlapping receptive fields. Nonetheless, the modestly-named "feasibility studies" summarized in this chapter show reasonable performance with one caveat: possibly due to the lack of generalization, the system often gets stuck on performance plateaus well before errors approach zero.
Although not implemented with neural networks in this chapter, Atkeson and Reinkensmeyer discuss possible neural network implementations of ACAMs. Control of a simulation for backing up tractor-trailer trucks is addressed by Derrick Nguyen and Bernard Widrow in chapter The truck backer-upper uses a common control scheme introduced in Barto's chapter to learn to back a truck from an arbitrary initial position to a loading dock, a difficult nonlinear control problem which this backprop-based model learns through several thousand training trials.
The specifics of this control problem are presented as one of the benchmark problems in the appendix.
No collection of papers on neural networks for control would be complete without a chapter that focuses on the cerebellum. The reason is simple; the cerebellum contains roughly half the cells in a human brain. It receives diverse spinal and cortical inputs, and the vast majority of its output cells project to motoneurons over pathways with only a few interposed synapses; moreover, the internal circuitry of the cerebellum suggests a huge array of nearly identical processing units.
Thus, to explain the key computational role of the cerebellum is simultaneously to explain half the brain and to characterize the nature of evolution's solution to the BIG PROBLEM in motor control as it has existed for vertebrate animals. A long series of computational proposals have been made by physiologists and neural network theorists, and many have been partially supported by experimental data.
In chapter 13, James Houk, Satinder Singh, Charles Fisher, and Andrew Barto sketch another new proposal regarding computational functions of the cerebellum, with an emphasis on how it may act in concert with peri-cerebellar circuitry.
This proposal assumes the thesis common to Ito , Kawato chapter 9 , Grossberg and Kuperstein , Fujita , and many others that error signals returned to the cerebellar cortex via climbing fibers help modify synaptic weights from parallel fibers onto Purkinje cells and thereby modify the level of inhibition exerted by Purkinje cells on motor pathways. The novel aspects of the current proposal are a that Purkinje cells inhibit positive feedback loops among reticular neurons, red nucleus cells, and deep cerebellar nuclear cells and b that the resultant composite circuit serves as a trajectory generator.These problems were selected to exemplify difficulties of incomplete system knowledge, nonlinearity, noise, and delays that arise in real control situations.
This approach thus provides the largest potential for novel contribution by neural network methods.

Several avenues for future research such as modifying the simulation to copy a human controller are also suggested to help lead to realization of more robust automatic landing systems.
