QUESTION
In this minimal reproducible example, I have a comboBox and a pushButton. I am trying to activate buttons on the basis of current text selected from the comboBox, but I can't able activate buttons when I tried to verify it first inside if elif else condition, how to activate right function on the basis of current text.
...ANSWER
Answered 2021-Jun-11 at 15:38Your logic is wrong since you seem to think that connecting the signal to another function will disconnect the signal from the previous function.
The solution is to invoke the appropriate function using the currentText of the QComboBox when the button is pressed.

...ANSWER
Answered 2021-Apr-12 at 12:14Your lambda is executed at some time after your loop has run completely. This means that the lambda will always be executed with the last object of the for loop.
To prevent this from happening, you can use a closure. Python has a simple way to create closures: Instead of a lambda use functools.partial

QUESTION
I want to generate a uniform random float number in the range of float numbers in the bash script. range e.g. [3.556,6.563]
basically, I am creating LSH(Latin hypercube sampling) function in bash. There I would like to generate an array as one can do with this python command line.
p = np.random.uniform(low=l_lim, high=u_lim, size=[n])
.
sample code :
...ANSWER
Answered 2020-Dec-02 at 15:52Most common rand()
implementations at least generate a number in the range [0...1)
, which is really all you need. You can scale a random number in one range to a number in another using the techniques outlined in the answers to this question, eg:
NewValue = (((OldValue - OldMin) * (NewMax - NewMin)) / (OldMax - OldMin)) + NewMin
For bash you have two choices: integer arithmetic or use a different tool.
Some of your choices for tools that support float arithmetic from the command-line include:
- a different shell (eg, zsh)
- perl:
my $x = $minimum + rand($maximum - $minimum);
- ruby:
x = min + rand * (max-min)
- awk:
awk -v min=3 -v max=17 'BEGIN{srand(); print min+rand()*int(1000*(max-min)+1)/1000}'
note: The original answer this was copied from is broken; the above is a slight modification to help correct the problem. - bc:
printf '%s\n' $(echo "scale=8; $RANDOM/32768" | bc )
... to name a few.

I'm trying to get constract date from handover report google spread sheet,
//here's sample handover report sheet https://docs.google.com/spreadsheets/d/1gVnj2LV60hBXmuiTDa287cNoN1VzroPJEPXl3w-SBF0/edit?usp=sharing
Then, I wanna set the value to cell that match with row including handover report ss id and column including "constract date" text.
//here's sample List sheet https://docs.google.com/spreadsheets/d/1Hu8dTsuH5iS9P0JGBlyN6pOWHo1hhe2t03Wih2BDRGw/edit?usp=sharing
But, nothing happen:( As you see, important to keep row&culumn dynamic for flexibility and expandability.
I sincerely appreciate the help.
...ANSWER
Answered 2020-Sep-22 at 14:19You define all functions inside of contractDate()
, but you never call them and never assign them parameters.
Also:
Your return 0;
statement should be placed after the for
loop - otherwise after the first iteration 0
will be returned if the if
condition is not fullfilled. Returning means that the function will halted before the iteration is complete.

QUESTION
As far as I understand one of the main functions of the LSH method is data reduction even beyond the underlying hashes (often minhashes). I have been using the textreuse
package in R, and I am surprised by the size of the data it generates. textreuse
is a peer-reviewed ROpenSci package, so I assume it does its job correctly, but my question persists.
Let's say I use 256 permutations and 64 bands for my minhash and LSH functions respectively -- realistic values that are often used to detect with relative certainty (~98%) similarities as low as 50%.
If I hash a random text file using TextReuseTextDocument
(256 perms) and assign it to trtd
, I will have:
ANSWER
Answered 2020-Aug-16 at 20:24Package author here. Yes, it would be wasteful to use more hashes/bands than you need. (Though keep in mind we are talking about kilobytes here, which could be much smaller than the original documents.)
The question is, what do you need? If you need to find only matches that are close to identical (i.e., with a Jaccard score close to 1.0), then you don't need a particularly sensitive search. If, however, you need to reliable detect potential matches that only share a partial overlap (i.e., with a Jaccard score that is closer to 0), then you need more hashes/bands.
Since you've read MMD, you can look up the equation there. But there are two functions in the package, documented here, which can help you calculate how many hashes/bands you need. lsh_threshold()
will calculate the threshold Jaccard score that will be detected; while lsh_probability()
will tell you how likely it is that a pair of documents with a given Jaccard score will be detected. Play around with those two functions until you get the number of hashes/bands that is optimal for your search problem.
QUESTION
The recent implementation of the Reformer in HuggingFace has both what they call LSH Self Attention and Local Self Attention, but the difference is not very clear to me after reading the documentation. Both use bucketing to avoid the quadratic memory requirement of vanilla transformers, but it is not clear how they differ.
Is it the case that local self attention only allows queries to attend to keys sequentially near them (i.e., inside a given window in the sentence), as opposed to the proper LSH hashing that LSH self attention does? Or is it something else?
...ANSWER
Answered 2020-May-21 at 23:47After closely examining the source code, I found that indeed the Local Self Attention attends to the sequentially near tokens.
QUESTION
The problem I am optimizing is the building of power plants in a transmission network. To do this I'm placing power plants at every bus and let the optimization tell me which ones should be build to minimize running cost.
To model the placing of the plant I tried using an array of binary variables that would flag i.e. be one if the plant is used at all and 0 otherwise. Then in the Objective function to minimize I multiply this array by a constant: USEW
.
I have made several attempt without any working. The one that seemed to work was using the if2 Gekko
function directly in the Obj. func. However I'm getting really odd results. My code is a bit long so I'll post just the relevant lines hopefully the idea would be clear, if not please let me know and I post the whole thing.
ANSWER
Answered 2020-May-20 at 12:01One thing that you can try is to use a switch point that is 1e-3 (or a certain minimum used) instead of zero. When the switch point is at zero and the condition is 1e-10
then the output will be 1
because it is greater than the switch point. This is needed because Gekko uses gradient based optimizers that have a solution tolerance of 1e-6
(default) so a solution within that tolerance is acceptable.
There are a couple examples in the documentation that may also help. You may also want to look at the sign2
/sign3
functions and the max2
/max3
functions that may also give you the desired result.
if2
Documentation
IF conditional with complementarity constraint switch variable. The traditional method for IF statements is not continuously differentiable and can cause a gradient-based optimizer to fail to converge. The if2
method uses a binary switching variable to determine whether y=x1
(when condition<0
) or y=x2
(when condition>=0
):
if3
Documentation
IF conditional with a binary switch variable. The traditional method for IF statements is not continuously differentiable and can cause a gradient-based optimizer to fail to converge. The if3
method uses a binary switching variable to determine whether y=x1
(when condition<0
) or y=x2
(when condition>=0
).
Usage
y = m.if3(condition,x1,x2)
Inputs:
condition
: GEKKO variable, parameter, or expressionx1
andx2
: GEKKO variable, parameter, or expression
Output:
y = x1
whencondition<0
y = x2
whencondition>=0
