A forward-propagation learning rule has been proposed to acquire neural inverse models. This rule can solve a credit assignment problem based on Newton-like method. In the current work, we discuss how to estimate the parameters of a multi-layered neural network based on the credit assignment. The suitability of the proposed estimation framework is confirmed by computer simulation.

Next generation mobile networks will face the unprecedented demand for higher data rates. To satisfy this demand, the dense deployment of heterogeneous wireless networks (HetNets) is a promising solution. One of the major challenges in dense HetNets is to dynamically allocate the resources such as power and channel so that the energy efficiency and throughput of the network improve. One of the important techniques for improving the energy efficiency of the base station (BS) is BS ON-OFF switching which allows the BS to turn off some of its components in lower load situations. On the other side, due to the proximity of BSs in the dense HetNets, co-channel interference (CCI) becomes a critical problem and significantly impacts the performance of the network. In this paper, we propose a dynamic channel assignment based on a learning algorithm (DCA-LA). Moreover, we combine DCA-LA with a BS ON-OFF switching algorithm in order to improve the energy efficiency of the system. In particular, the proposed DCA-LA/ON-OFF switching algorithm is self-organizing and performs in a fully distributed manner. Simulation results indicate that our proposed algorithm balances load among BSs and yields better performance in terms of average energy consumption, average load, average utility per BS and average rate per user, compared to the baseline algorithms.

Extreme learning machine (ELM) is originally proposed for single-hidden layer feed-forward neural networks (SLFN). From the functional equivalence of fuzzy logic systems and SLFN, the fuzzy logic systems can be interpreted as a special case of SLFN under some mild conditions. Hence the fuzzy logic systems can be trained using SLFN's learning algorithms. Considering the same equivalence, ELM is utilized here to train interval type-2 fuzzy logic systems (IT2FLSs). Based on the working principle of the ELM, the parameters of the antecedent of IT2FLSs are randomly generated while the consequent part of IT2FLSs is optimized using Moore-Penrose generalized inverse of ELM. Application of the developed model to electricity load forecasting is another novelty of the research work. Experimental results shows better forecasting performance of the proposed model over the two frequently used forecasting models.

Machine learning has been a focus research topic of superior tasks in many real-world applications. One of the famous preferred system is neural network. This approach has been invented for decades but becomes popular recently due to its satisfied results in many applications. The success of applying neural network involves model training which conventionally uses backpropagation method. However, it has many drawbacks. In recent decades, Extreme learning machine (ELM) was first proposed for training single-hidden layer feedforward neural network (SLFN). It optimizes training error by utilizing the whole training dataset with a one-shot calculation. However, for the training in datasets with large number of input features or high dimensional datasets, original ELM encounters many difficulties. One of them is that the original ELM has no learning process from an input layer. This lead to an incomplete representation of data when it is transferred from one layer to another. Another difficulty involves training instability which causes fluctuation in testing accuracy. This is because networks' input weights are randomly generated. To circumvent these difficulties, the imposing architecture, namely Extended Extreme learning Machine (X-ELM), is proposed. X-ELM uses ELM as an extension part in order to predict the outputs based on ensemble approach. The proposed framework extends the usage of ELM to apply to more complex network structures, such as networks with multiple hidden layers or networks with multiple computing systems. The proposed framework is applied to vehicles characteristic classifications' datasets. The experimental results show that X-ELM achieves better testing accuracy than of ELM in real-world applications.

Also learning algorithm for all its parameters (synaptic weights, the centers, and widths of wavelet activation functions) based on cross entropy cost function was proposed. The proposed system is characterized by high learning speed and high approximation properties in comparison with well-known approaches. The efficiency of the proposed approach has been justified based on different benchmarks and real data sets.

We present a novel approach, Equilibrium Point learning (EPL), for training the deep equilibrium model (DEQ). In this method, the equilibrium point of the DEQ serves as the learnable parameters. Notably, the DEQ parameters encapsulate the learning algorithm itself and remain fixed. Consequently, by exploring the parameter space, we can discover a more efficient learning algorithm without relying on conventional techniques such as backpropagation or Q-learning. In this paper, we adopt an evolutionary approach inspired by biological neurons to evolve the DEQ model parameters. Initially, we examine the physical dynamics of neurons at the molecular level and translate them into a dynamical system representation. Subsequently, we formulate a deep implicit layer that is mathematically proven to possess an equilibrium point. The energy function of the implicit layer is defined using a quadratic form augmented with entropy and momentum terms. Given the resemblance between the dynamics of the deep implicit layer and the principles of physics and chemistry, it can effectively capture the biomodel of systems biology and the neural model of spiking neural networks (SNNs). This equivalence enables us to define the implicit layer of the DEQ, allowing for seamless integration with existing artificial neural networks (ANNs). Finally, we employ HyperNEAT to evolve the parameters of the dynamical system. Through our experiments, we observe a consistent improvement in learning efficiency, with each successive generation exhibiting a 0.2% increase in learning speed per generation.

In this study, we have developed a method that applies machine learning in combination with an optimization heuristic algorithm such as a genetic algorithm (GA) for solving the vehicle routing problem (VRP). Further, we developed a knowledge-based algorithm for a knowledge learning system. The algorithm learns to classify coordinates (unlabeled) into regions. Consequently, dividing routing calculations into regions (clusters) provides many benefits over traditional methods, and can result in an improvement in routing cost over the traditional company method by up to 25.68% and over the classical GA by up to 8.10%. It is also shown that our proposed method can reduce traveling distance compared to previous methods. Finally, the prediction of future customer regions has an accuracy of up to 0.72 for the predicted unlabeled customer coordinates. This study can contribute toward creation of more efficient and environmentally friendly urban freight transportation systems.

In this work, an intelligent and reconfigurable ultra-wideband angular sensing (UWAS) framework is proposed which is independent of the maximum number of active transmissions in a wideband spectrum unlike the existing UWAS methods. To perform the above task, we propose a sub-Nyquist sampling and sparse ruler based multi-antenna array receiver architecture. By characterizing and selecting a set of frequency bands via a learning algorithm, the proposed receiver allows sensing of more active transmissions than the number of antenna over an unlimited bandwidth. The simulation results show that due to the learning based approach, the proposed UWAS outperforms when compared to non-learning based UWAS method.
