本文首先介绍 上的微分形式的一些理论,然后用微分形式的语言重新书写、理解 vector calculus 中梯度、散度和旋度的概念。 我们首先来看一下余切空间和余向量场(即微分 1-形式)的定义。 定义…阅读全文 赞同43 1 条评论 分享收藏 流形(Manifolds) -- (4) 张量积,楔积和外代数 我们首先来...
The vectors do not have to be 4-vectors. I have one more question: Are you familiar with the more abstract stuff like vector spaces? If you are, I can only suggest presenting tensors in that setting, as it greatly helped me. I found it very useful to first see the definition of a...
We're not knocking calculus. We love calculus and have even taught it at the college level, but we don't think it's the best place to start when learning deep learning! In deep learning, it really helps if you have the motivation to fix your model to get it to do better. That's...
to be treated as a vector and incorporated into the vector calculus. Area treated as a vector also has a directional sense by convention, only. The most subtle of all the artificial vectors are the axial vectors. Take the vector representing torque. This vector points along the axis of the...

In the Wolfram Language, exact input (like fractions) will provideexact output: (UseCTRL+/to enter fractions.) Any input containing decimals gives approximate output: In[1]:= .25 + 1/3 Out[1]= UseNto get a numerical approximation of a result: ...
One hundred measurements of soil electrical conductivity collected in a forest stand compose a single observation of a 100-dimensional homogeneous multivariate vector. Heterogeneous multivariate observations arise when the responses that are modeled jointly refer to different attributes, such as in the ...
In the 17th century several mathematicians developed the concepts of limits and continuity, primarily to foster the development of calculus. If f(x) gets closer and closer to q, as x gets close to p, then the limit of f, at p, is q. If f(p) = q then f is continuous at q. Int...
