Based on the strong analogy between neuralnetworks and distributed diagnosis models, diagnostic algorithms are presented which are similar to the learning algorithm used in neuralnetworks. Diagnostic implications of convergence theorems proved by the Lyapunov function are also discussed. Regarding diagnosis process as a recalling process in the associative memory, a diagnostic method of associative diagnosis is also presented. A good guess of diagnosis is given as a key to recalling the correct diagnosis. The authors regard the distributed diagnosis as an immune network model, a novel PDP (parallel distributedprocessing) model. This models the recognition capability emergent from cooperative recognition of interconnected units

A distributed robot control system is proposed based on a temporal self-organising neuralnetwork, called competitive and temporal hebbian (CTH) network. Tire CTH network can learn and recall complex trajectories using two sets of synaptic weights, namely, competitive feedforward weights that encode the individual states of the trajectory, and hobbian lateral weights that encode tire temporal order of trajectory states. Ambiguities that occur during trajectory reproduction are resolved using temporal context information. Also, the CTH network saves memory space by maintaining only a single copy of each repeated/shared state of a complex trajectory. A distributedprocessing scheme is proposed to evaluate the CTH network in point-to-point real-time trajectory control of a PUMA 560 robot. The performance of the control system is discussed arid compared with other neuralnetwork approaches.

We compare two optimization methods for lattice-based sequence discriminative training of neuralnetwork acoustic models: distributed Hessian-free (DHF) and stochastic gradient descent (SGD). Our findings on two different LVCSR tasks suggest that SGD running on a single GPU machine achieves the best accuracy 2.5 times faster than DHF running on multiple non-GPU machines;however, DHF training achieves a higher accuracy at the end of the optimization. In addition, we present an improved modified forward-backward algorithm for computing lattice-based expected loss functions and gradients that results in a 34% speedup for SGD.

distributed array consisting of multiple subarrays is attractive for high-resolution direction-of-arrival (DOA) estimation when a large-scale array is infeasible. To achieve effective distributed DOA estimation, it is required to transmit information observed at the subarrays to the fusion center, where DOA estimation is performed. For noncoherent data fusion, the covariance matrices are used for subarray fusion. To address the complexity involved with the large array size, we propose a compression framework consisting of multiple parallel encoders and a classifier. The parallel encoders at the distributed subarrays are trained to compress the respective covariance matrices. The compressed results are sent to the fusion center where the signal DOAs are estimated using a classifier based on the compressed covariance matrices.

To make network intrusion detection systems can be used in Gigabit Ethernet, a distributedneuralnetwork learning algorithm (DNNL) is put forward to keep up with the increasing network throughput. The main idea of DNNL is splitting the overall traffic into subsets and several sensors learn them in parallel way. The advantage of this method is that the large data set can be split randomly thus reduce the complicacy of the splitting algorithm. The experiments are performed on the KDD'99 Data Set which is a standard intrusion detection benchmark. Comparisons with other approaches on the same benchmark show that DNNL can perform detection with high detection rate.

The Artificial neuralnetwork(ANN) is an intelligent computer system bases on the empirical teaming of the human being. Knowledge-Based Artificial neuralnetworks(KBANN) effectively combines the knowledge learnt from theory with that of learnt from examples. This efficient combination of theory and data may result in efficient teaming system. And the method of building a KBANN solves the problem that how to design the structure of the neuralnetwork. According to the way of building a KBANN, interpreting system of Remotely-Sensed images can be built.

In recent years, some researchers have been exploring quantum computer in view of neuralnetwork to realize a distributed and strongly connectionist system that achieves parallel and fast information processing. We have proposed a qubit neuron model based on quantum mechanics, constructed the Quantum Back Propagation learning rule(QBP), and investigated it. In this paper, we show our improved QBP neuralnetwork model and discuss its performance on solving the 4 bit parity check problem and the function identification problem. Then, we conclude our model is more excellent than the conventional one in information processing efficiency.

This paper studies the distributed convex optimization problems, where the objective function can be expressed as the sum of nonsmooth local convex objective functions. By the virtue of KKT conditions, an artificial neuralnetwork is presented to solve the distributed convex optimization problems with inequality and equality constraints. And it is shown that the state solution of the artificial neuralnetwork converges to the optimal solution to the original optimization problem. Compared with the existing continuous time algorithms, the provided algorithm has the advantages of lower model complexity and easy implementation. Finally, a numerical example displays the practicality of the algorithm.

Privacy preservation is critical for neuralnetwork inference, which often involves collaborative execution of different parties to make predictions on sensitive data based on sensitive neuralnetwork models. However, the expensive cryptographic operations of privacy preservation also pose performance chal-lenges to neuralnetwork inference. We address this performance-security tension by designing PP-Stream, a distributed stream processing system for high-performance privacy-preserving neuralnetwork inference. PP-Stream adopts hybrid privacy-preserving mechanisms for linear and non-linear operations of neuralnetwork inference. It treats inference data as real-time data streams, and parallelizes the inference operations across multiple pipelined stages that are executed by multiple servers and threads. It also solves the load-balanced resource allocation across servers and threads as an optimization problem. We prototype PP-Stream and show via testbed experiments that it achieves low inference latencies on various neuralnetwork models.

This paper studies distributed optimization of an uplink cell-free Massive MIMO (CF-mMIMO) network. By observing some interesting analogies between the CF network and an artificial neuralnetwork (ANN), we propose to relate the uplink CF network to a so-called quasi-neuralnetwork. Borrowing the idea of the back-propagation (BP) algorithm, we propose a novel scheme to optimize the central processing unit (CPU) and the access points (APs) of the network. The proposed scheme can achieve multi-AP cooperation using only the pilot sequences, but without the channel state information (CSI). To reduce the required throughput of the fronthaul, we let each AP beamform the received vector signals into scalar ones before passing them to the CPU. The effectiveness of the proposed scheme is verified by the simulations.
