三、ML模型最终进化——Deep Learning 在第二部分的function中,我们拟合了许多个sigmoid函数,sigmoid函数内部又是线性的函数。最终,形成了如下图所示的一个数据流。 其实,我们在得到[a1,a2,a3]之后,还可以将[a1,a2,a3]再次作为输入,输入到另一个类似结构中去,如下所示:这样子所形成的模型够更好的拟合数据。 ...
Y(x)=f(x)-x^2-2x-1 我们可以知道,对于一个样本(x,f(x)),如果它的值大于0,那么它属于B区域;如果它的值小于0,那么它属于A区域。 深度学习算法只不过是一个非常复杂的f(X),而模型训练就是指通过某种迭代策略,通过训练数据集(样本和标签),确定这个复杂f(X)的参数的过程;确定好的参数量级很大,保存为...
人工智能(ArtificialIntelligence,AI)是最宽泛的概念,是研发用于模拟、延伸和扩展人的智能的理论、方法、技术及应用系统的一门新的技术科学 机器学习(MachineLearning,ML)是当前比较有效的一种实现人工智能的方式。 深度学习(DeepLearning,DL)是机器学习算法中最热门的一个分支,近些年取得了显著的进展,并替代了大多数传统...

Deep learning is a subset of machine learning that leverages neural networks with multiple layers to automatically learn patterns and relationships in data. These networks are trained on large datasets, such as weather conditions, energy consumption, and traffic congestion, and can identify patterns and...
Deep learning is a subset of machine learning. To train deep learning models, large quantities of data are required. Patterns in the data are represented by a series of layers. The relationships in the data are encoded as connections between the layers containing weights. The higher the weight...
Deeper is better? 毫无疑问,参越多,效果越好。 但是在比较两种不同的架构时,却不一样。 为什么参数增加了效果反而差? Modularization 因为架构越深,相当于模块化越多。 考虑一个问题,笼统的解决方法: 但是把问题慢慢细分,解决效果会更好。 image.png
