turbulence | Hopefully-meaningful metrics | Analytics library

I'm working on a project where I have to keep track of model performance across different version releases. I'm trying to create and write a text file that contains some lines of text that signal turbulences in the model performance. This is the function I wrote (it contains some auxiliary functions but these are not relevant for my question):

I want to add some constraints to the following code in which I want to optimize the output using scipy.

I am trying to add this animated svg noise background here in place of the red background in my code that is below this one.

Is there way to accomplish the code below with out the for loop?

I’m assigning int values to str based on its index position.

So I want to render SVG from python code having target resolution WxH (having SVG text as str, like this that I generate dynamically):

When experimenting with the feTurbulence filter primitive, I'm getting thin, dark lines throughout where I wouldn't expect them. They're most visible when numOctaves="1". Why are they there?

Let's say I start with the reference code from https://www.w3.org/TR/SVG11/filters.html#feTurbulenceElement (fixing it so it compiles). I call it as

I am trying to create water effect in my application to simulate water in pool. I got animation working with feTurbelance but my top left corner is not moving and it looks like animation is toward bottom right corner where water movement is fastest. Is possible to move that source point to middle of the screen or even better to have movement same across the screen?

I am using a quiver plot in MATLAB to simulate a velocity field. Now I would like the vectors produced by the quiver plot to be all the same length, so that they just indicate the vectors direction. The value of the velocity in each point should be illustrated by different colors then. Is there a possibility to have quiver plotting vectors of same length?

That's my current code:

I am trying to achieve a paint-on-paper effect on shapes in SVG by applying:

• a displacement filter and
• a blur

Everything works ok on the background, but if I try to apply the same filter to shapes in the foreground, it results in a weird border around the shape itself, that gets even worse if the shape is a path.

This is the version without filter on the shape, this is the one with the filter applied to a rotated rect and this is the version where the filter is applied to a path. BTW, the displacement and blur filters seem to work ok only in Firefox.

The code for the rect version is below.

Can I apply the diffuse lighting filter to the shape without the weird border?
