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
Find out why backpropagation and gradient descent are key to prediction in machine learning, then get started with training a simple neural network using gradient descent and Java code.
In a gradient descent process, when searching for the minimum, it always follows the direction that is against the direction represented by the negative gradient. The gradient can be calculated based on the algorithm differentiation module we have introduced in Chapter 3. That's why the whole ...
In this post, I will: Answer why might one want to use an IIR filter. Explain how an IIR filter efficiently “inverts” a convolutional filter. Elaborate on the challenges of using an IIR filter. Propose a gradient descent, optimization, and data-driven method to find a suitable IIR filte...

In this work, we consider image deblurring by assuming non-uniform AWGN, which is more consistent to the real-world noise [35]. We adopt the gradient descent unrolling framework in RGDN [28] because the gradient descent iteration in Eq. (11) for uniform AWGN can be easily extended to non...

Q:“turn out” in “It turns outgradientdescent is a more general algorithm, and is used not only in linear regression. “是什麼意思 A:“Turn out” can mean “unexpectedly it’s true that___”. For example if you hear all around town that a certain restaurant is super fancy and ele...
