The log-derivative trick is based on a simple rule from calculus: the derivative of with respect to is . When rearranged and combined with chain rule, we get: 3. Log-Probability of a Trajectory. The log-prob of a trajectory is just 4. Gradients of Environment Functions. The environment ...
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...
Machine learning, at its heart, is deeply rooted in mathematics. From linear algebra to calculus, various mathematical concepts play a pivotal role in designing and understanding ML algorithms. Let’s delve into some of these foundational elements. Role of Mathematical Optimization Optimization is the...
If you know some vector calculus, you can prove all of this, which definitely helps with understanding it, but if not, just remember that a conservative force is a special kind of force where the work on any round-trip will be zero. And friction is decidedly NOT a conservative force (as...
We're not knocking calculus. We love calculus, and Sylvain has 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....
