Course 4-Convolutional Neural Networks--Week 4 本周的内容主要围绕人脸识别展开,主要包括face verification、face recognition、neural style transfer。 4.1 What is face recognition? 首先来看看人脸识别领域的一些术语。如下图所示,分别说明了人脸确认和人脸识别的概念。人脸确认是个1对1的问题,而人脸识别比人脸...
神经网络:表述( Neural Networks: Representation) 神经网络:表述 Neural Networks: Representation 当我们使用 x 1 、x 2 的多次项式进行预测时,我们可以应用的很好。 之前我们已经看到过,使用非线性的多项式项,能够帮助我们建立更好的分类模型。假 设我们有非常多的特征,例如大于 100 个变量,我们希望用这 100 个...
(五)、分类问题(Classification) 本章主要围绕神经网络的建模及其线性表示(即neural networks的representation)做以初步了解,在下一章中将会有更详细的神经网络如何学习方面的知识。 === (一)、为什么引入神经网络?——Nonlinear hypothesis 之前我们讨论的ML问题中,主要针对Regression做了分析,其中采用梯度下降法进行参数...
1.1intro application: read handwriting Representation This week, we are covering neural networks. Neural networks is a model inspired by how the brain works. It is widely used today in many applications: when your phone interprets and understand your voice commands, it is likely that a neural n...
The semantic representation if the two nodes are merged. Score of how plausible the new node would be, i.e. how matching the two merged words are. Let’s say a parent has two children In place of and , there can be two words from a sentence as seen in the above picture. By checki...

[63] suggested a trajectory design technique for overtaking maneuvers built on a simple mathematical representation of possible trajectories utilizing the potential field approach. Here, neural networks are used to approximate the solution of the optimization's complex calculations. A unique strategy for ...
CryoDRGN is a neural network based algorithm for heterogeneous cryo-EM reconstruction. In particular, the method models acontinuousdistribution over 3D structures by using a neural network based representation for the volume. Documentation The latest documentation for cryoDRGN is available in ouruser gui...
