After a long journey about the Mathematics of Forward Kinematics and the geometrical details of gradient descent, we are ready to finally show a working implementation for the problem of inverse kinematics. This
If the solution to a task can be found with the greedy algorithm, it has an optimal substructure. The optimal substructure property is the same as that in DP. I provided a way to prove if a task has an optimal substructure in the summary of chapter 3 3. Batch Gradient Descent for Line...
For now, let's move on to another aspect of optimization: the gradient descent algorithm. Gradient We have provided the framework of gradient methods in Section 4.1. However, there exist many variants of gradient descent algorithms. They are included in the Gradient module. The code is shown...
The biggest barrier to understanding backpropagation with gradient descent is the calculus involved. Once that is understood, the overall idea is not hard to grasp and apply in code. See the following resources to learn more about gradient descent: Gradient descent algorithm—a deep dive Neural ...
This type of error is also highly data-dependent. On one input, the algorithm might perform perfectly, while on another one, the error can become catastrophic. This is challenging for debugging, testing, and creating “robust” systems.
gradient descent algorithm, we learn the inverse covariance of the non-uniform AWGN, the gradient of the regularization term, and the gradient adjusting factor from data. To achieve this, we unroll the gradient descent iteration into an end-to-end trainable network, where, these components are ...
