We refer to the agent that plays this single-player game as AlphaDev. The agent’s primary learning algorithm is an extension of the AlphaZero agent32and guides a Monte Carlo tree search (MCTS) planning procedure using a deep neural network33,38. The input to the neural network is the st...
Algorithms for verifying conditions under which Hopf bifurcation occurs in systems of ordinary differential equations35B32Necessary and sufficient conditions that a system of ordinary differential equations satisfy the conditions of the Hopf bifurcation theorem are obtained and algorithm are provided by which...
The final layers are fully connected layers, similar to the classical neural networks. The convolution operation helps the network to focus on local features. Python Code Example (For simplicity, a pseudo-code-like approach is presented here.) # Assuming a deep learning framework like TensorFlow ...
DL is a subset of ML that use ANN (Artificial Neural Network) for computation. DL is composed of deeply layered neural networks. The term “deep” refers to the number of hidden layers in the NN, that is why DL models are often referred to as DNN. DL models can be categorized into s...
Although evolutionary optimization algorithms can be used in this way, more often they’re used to find the values for a set of numeric parameters in a larger optimization problem for which there’s no effective deterministic algorithm. For example, when using a neural network to classify ...
The security descriptor is the basis for specifying the security associated with an object. The client makes a request to the server that indicates a particular requested access, and the server that "owns" the object is responsible for verifying that a client has sufficient access to the objec...

Yasuda and Ohkura [152], [153] used a DQN combined with a deep neural network (DNN) to control a swarm of ground robots. Unlike some previous work, in their system, the agents uploaded their input/output reward to a central server, which contained an experience replay memory [154]. Inst...
support vector regression36, k-means clustering37, classification and regression tree38, multi-layer perceptron34, and neural networks39,40,41,42have been extensively and effectively utilized by researchers for identifying landslide susceptibility. However, the development of newer and more powerful algor...
Classifiers based on neural networks A neural network (NN) is made up of units (neurons) that are organized in layers that convert an input vector into some output. Each unit receives an input, applies a (typically nonlinear) function to it, and then forwards the output to the next layer...
