也就是说,权值衰减在模型中不单单起到正则化作用;它还协助降低模型的训练错误率。
In other words, weight decay here is not merely a regularizer: it reduces the model's training error.
我们可以看到,CNN神经网络的隐层节点的连接权值参数可以共享。
We can see that the connection weight parameters of nodes on the hidden layer of a CNN neural network can be shared.
反向传播是梯度下降的一种形式,炼金术用它来优化马尔科夫逻辑网络权值。

同理,当计算机为两张图像建立相似度联系时,它将为这些相似度分配权值。
In a similar vein,when computers establish similarities between two images it assigns a weight to those similarities.
现在这些权值对我们来说并不重要,但是我们将在后面使用这些数字来测试我们的感知器。
The weights don't mean much to us right now, but we will use those numbers in the next section to test our perceptron.
增长核算的原理是,投入要素增长率的加权值是否大于产出的增长率。
The principle of growth accounting is to ascertain whether the weighted sum of factor growths is larger than the growth rate of total output.
如果我们引入权值上的高斯先验,那么我们就得到了第4章讨论过的模型。
If we introduce a Gaussian prior over the weight vector w, then we obtain the model that has been considered already in Chapter 4.
如果权值是常数,那么混合模型的参数可以由第9章讨论的EM算法确定。
If the weights were constant, then the parameters of the mixture model could be determined by using the EM algorithm discussed in Chapter 9.
他们将一种形式的权值共享应用在了一段电影评论的情感分析和与贫血症有关的生物医学搜索中。
They applied a form of weight sharing to a sentiment analysis of movie reviews and to a biomedical search related to anemia.
相反,联结学派更喜欢用一个简单、手工编写的结构,加上许多连接行为,然后让权值学习来完成所有工作。
In contrast, connectionists prefer to take a simple,hand-coded structure with lots of connections and let weight learning do all the work.
神经网络经常需要处理不同大小的输入矩阵和权值矩阵,它们的维度常常不满足矩阵相乘的规则。
Neural networks frequently process weights and inputs of different sizes where the dimensions do not meet the requirements of matrix multiplication.
在第二阶段,算法计算一个错误,然后将此错误从最后一层反向传播(调节权值)到第一层。
In the second phase, the algorithm computes an error,and then backpropagates this error(adjusting the weights) from the final layer to the first.
不幸的是,这样做只会让权值不受限制地增长,因为从数学的角度讲,权值越大,边际越大。
Unfortunately, this would just make the weights grow without limit, because mathematically, the larger the weights, the larger the margin.
终极算法既不是遗传编程,也不是反向传播,但它得包含这两者的重要部分:结构学习和权值学习。
The Master Algorithm is neither genetic programming nor backprop, but it has to include the key elements of both:structure learning and weight learning.
大多数人工神经网络有两个共同点:大量的权值,本质上是网络在训练中学习的可调参数;
Most artificial neural networks have two things in common:a huge number of weights, which are essentially the tunable parameters that networks learn during training;
量化过程基本上是将机器学习模型中权值的大小从32位浮点权值减少到16位或8位的精度。
What quantization basically does is reducing the size of the weights in a machine learning model, from 32-bit floating point weights to 16 or 8-bit precision.
