A deep neural network (DNN) is an artificial neural network consisting of multiple layers between the input and output layers. These layers could be recurrent neural network layers or convolutional layers making DNN’s a more sophisticatedmachine learning algorithm. DNNs are capable of recognizing sou...
Neural networksis a model inspired by how thebrain works. It is widely used today in many applications: when your phone interprets(解释口译) and understand your voice commands, it is likely that a neural network is helping to understand your speech; when youcash a check(支票兑现), the mach...

In machine learning, an artificial neural network is an algorithm inspired from biological neural network and is used to estimate or approximate functions that depend on a large number of generally unknown inputs. An artificial neural network is composed of a large number of interconnected neurons ...

Perceptron model is an early as well as simple form of neural network introduced in 1958 by Frank Rosenblatt. It is the primary model of today's machine learning. Though it is quite simple, the process of it still involves in a great amount of algorithms. So, we are not going to discus...
