kandi X-RAY | minipack Summary
As front-end developers, we spend a lot of time working with tools like Webpack, Browserify, and Parcel. Understanding how those tools work can help us make better decisions on how we write our code. By understanding how our code turns into a bundle and how that bundle looks like we can also debug it better. The purpose of this project is to explain how most bundlers work under the hood. It contains a short implementation of a simplified but still reasonably accurate bundler. Along with the code, there are comments explaining what the code is trying to achieve.

QUESTION
I have implemented a 3D gaussian fit using scipy.optimize.leastsq
and now I would like to tweak the arguments ftol
and xtol
to optimize the performances. However, I don't understand the "units" of these two parameters in order to make a proper choice. Is it possible to calculate these two parameters from the results? That would give me an understanding of how to choose them. My data is numpy arrays of np.uint8
. I tried to read the FORTRAN source code of MINIPACK but my FORTRAN knowledge is zero. I also read checked the Levenberg-Marquardt algorithm, but I could not really get a number that was below the ftol
for example.
Here is a minimal example of what I do:

Answered 2021-Mar-10 at 11:30Since you are giving a function without the gradient, the method called is lmdif. Instead of gradients it will use forward difference gradient estimate, f(x + delta) - f(x) ~ delta * df(x)/dx
(I will write as if the parameter).
There you find the following description

I have one sales data and product details in two lookup table

The coalesce
function allows you to merge the description

That depends on you field-content. Keep in mind, that fields with type = string are not tokenized!
See the solr docs: https://lucene.apache.org/solr/guide/7_3/field-types-included-with-solr.html (Class StrField)
String (UTF-8 encoded string or Unicode). Strings are intended for small fields and are not tokenized or analyzed in any way. They have a hard limit of slightly less than 32K.
So your query will match an field, only if the field content matches exactly the query content.
For example field content ABC DE
will not match an query like ABC DE
(one space is missing between the letters at the query)
I recommend using the solr analysis feature from the solr admin page to see, how solr processes your query. You will find this feature at an url like this: http://:8983/solr/#//analysis
