Neural Networks Rival the Primate Brain at Object Recognition A central problem in computer vision is that of designing algorithms that can competently accomplish tasks that humans can easily do, such as recognizing objects. Recently, neuroscientists at MIT found that the latest artificial deep neural networks (DNNs) are able to rival the performance of the primate brain at this task.

Op deze chinese site vind je een zeer goede, eenvoudige uitleg over hoe je een artificiëel neuron / artificiëel neuraal netwerk kunt omschrijven.
http://bbs.pinggu.org/thread-4192156-1-1.html So what is a neural network? Let’s wait with the network part and start off with one single neuron. A neuron is like a function; it takes a few inputs and calculates an output. The circle below illustrates an artificial neuron. Its input is 5 and its output is 1. The input is the sum of the three synapses connecting to the neuron (the three arrows at the left).At the far left we see two input values plus a bias value. The input values are 1 and 0 (the green numbers), while the bias holds a value of -2 (the brown number). The inputs here might be numerical representations of two different features. If we’re building a spam filter, it could be whether or not the email contains more than one CAPITALIZED WORD and whether or not it contains the word ‘viagra’. The two inputs are then multiplied by their so called weights, which are 7 and 3 (the blue numbers). Finally we add it up with the bias and end up with a number, in this case: 5 (the red number). This is the input for our artificial neuron. |

The neuron then performs some kind of computation on this number — in our case the Sigmoid function, and then spits out an output. This happens to be 1, as Sigmoid of 5 equals to 1, if we round the number up (more info on the Sigmoid function follows later). If this was a spam filter, the fact that we’re outputting 1 (as opposed to 0) probably means that the neuron has labeled the text as ‘spam’. |

If you connect a network of these neurons together, you have a neural network, which propagates forward — from input output, via neurons which are connected to each other. |

The Sigmoid function simply maps your value (along the horizontal axis) to a value between 0 and 1. |
In november 2016 werd bij Google Translate
overgeschakeld van PBMT naar NMT. Onder meer voor het belangrijke talenpaar Engels/Chinees. In Google Translate zaten op dat ogenblik 103 talen. Dit wil zeggen 103 in het kwadraat talenparen. 103 x 103 = 10.609 modellen Die modellen worden allemaal met data gevoed.
Artificiële Neurale Netwerken. The Artificial Intelligence Behind Google Translate Recently Did Something Extraordinary |
Baidu Translate: The Inside Story “Baidu Translate is based on deep learning technology,“Deep Learning technology performs much better than PBMT” (Baidu Translate) Confirmed: Deep Learning Is Coming to Google Translate Google confirmed they plan to improve Google Translate’s accuracy through artificial intelligence called deep learning. Deep learning is an advanced model of machine learning where an algorithm takes what it has already “learned” (data previously processed) and uses it to form new ways to solve problems in a pattern. |
