向量的一种特殊乘法 element wise multiplication 物体反射颜色的计算采用这样的模型: vec3 reflectionColor = objColor * lightColor;//物体反射颜色 = 物体颜色 * 光源颜色. (vec3(r,g,b), r,g,b在[0,1]范围里). 比如:光源是自然光:lightColor = vec3(1.0,1.0,1.0);物体是绿色的:objColor  = vec3(0,0,1.0,0.0); 反射光就是:reflectio…
Understanding Convolution in Deep Learning Convolution is probably the most important concept in deep learning right now. It was convolution and convolutional nets that catapulted deep learning to the forefront of almost any machine learning task the…

Sequence Models This is the fifth and final course of the deep learning specialization at Coursera which is moderated by deeplearning.ai Here are the course summary as its given on the course link: This course will teach you how to build models for n…
About this Course This course will teach you how to build models for natural language, audio, and other sequence data. Thanks to deep learning, sequence algorithms are working far better than just two years ago, and this is enabling numerous exciting…
About this Course This course will teach you how to build convolutional neural networks and apply it to image data. Thanks to deep learning, computer vision is working far better than just two years ago, and this is enabling numerous exciting applica…
About this Course This course will teach you the "magic" of getting deep learning to work well. Rather than the deep learning process being a black box, you will understand what drives performance, and be able to more systematically get good res…
(一)KNN依旧是一种监督学习算法 KNN(K Nearest Neighbors,K近邻 )算法是机器学习全部算法中理论最简单.最好理解的.KNN是一种基于实例的学习,通过计算新数据与训练数据特征值之间的距离,然后选取K(K>=1)个距离近期的邻居进行分类推断(投票法)或者回归.假设K=1.那么新数据被简单分配给其近邻的类.KNN算法算是监督学习还是无监督学习呢?首先来看一下监督学习和无监督学习的定义.对于监督学习.数据都有明白的label(分类针对离散分布,回归针对连续分布),依据机器学习产…
看官方解释 element element  例子: div p 官方解释:div内部所有的p元素 就是说 只要p在div内部.如果 p在span内部,span在div内部,p也算在div内部 <!DOCTYPE html> <html> <head> <style> div p { background-color:yellow; } </style> </head> <body> <div> <p&g…
