QUESTION
I am a beginner on mlr3 and am facing problems while running AutoFSelector learner associated to glmnet on a classification task containing >2000 numeric variables. I reproduce this error while using the simpler mlr3 predefined task Sonar. For note, I am using R version 4.1.2 (2021-11-01)on macOS Monterey 12.1. All required packages have been loaded on CRAN.
...ANSWER
Answered 2022-Jan-24 at 18:05This is a problem specific to glmnet
. glmnet
requires at least two features to fit a model, but in at least one configuration (the first ones in a sequential forward search) you only have one feature.
There are two possibilities to solve this:
- Open an issue in mlr3fselect and request a new argument
min_features
(there already ismax_features
) to be able to start the search with 2 or more features. - Augment the base learner with a fallback which gets fitted if the base learner fails. Here is fallback to a simple logistic regression:

I have two dataframes- df1 having columns like ISIN, Name, Weight and df2 having columns like Short Name, ISIN.
df1 =

Answered 2021-Dec-13 at 15:03You can use split to get the result. I search if the first word in df1.Name is in df2.Short Name
QUESTION
I am a very new coder trying to build my first app. I have created a login page but something seems to be blocking it. I am not sure why it is not working, could it be a small error or something else? My sign-up page works fine but the login does not even click through. Can anyone help find what might be the error in my code?
...ANSWER
Answered 2021-Dec-12 at 08:19Check your login function, in the javascript it doesn't have event while in the signup it has an event in it's argument. This may help.
QUESTION
When I multiply two big integers using FFT, I find the result of FFT and IFFT is always not right.
methodTo realize FFT, I just follow the pseudocode as followed: the pseudocode of FFT
The equations of FFT and IFFT are as followed. So, when realizing IFFT, I just replace a
with y
, replace omega
with omega ^^ -1
and divide it by n
. And, use flag
to distinguish them in my function.
To find the problem, I try to compare the results between numpy.fft and my function.
- FFT.
The results of numpy and my function look the same, but the sign of images is the opposite. For example (the second element of case2 below):
- my function result:
-4-9.65685424949238j
- numpy result:
-4+9.65685424949238j
- my function result:
- IFFT. I just find it wrong, and can't find any rule.
Here is my function FFT, and comparison:
...ANSWER
Answered 2021-Dec-07 at 17:50As was pointed out in comments, you used a positive sign in the computation of omg_n
. There are different definitions of the DFT, so it isn't wrong by itself. However this would naturally lead to differences if you compare your results with an implementation that uses a negative sign, as is the case with numpy.fft.fft
. Adjusting your implementation to also use a negative sign would cover all forward transform cases (leaving only small roundoff errors on the order of ~10-16).
For the inverse transform cases, your implementation ends up scaling the result by 1/n
at every stage, instead of only the final stage. To correct this, simply remove the scaling from the recursion, and normalize only on the final stage:

So I was working with particles.js and it works on the safari browser (Im on a MacBook) but on chrome it throws the error and the particles do not show up.
...ANSWER
Answered 2021-Sep-24 at 12:42The error is because particle.js cant load two json-Files.
/particlesjs-config.json and /assets/particles.json
Check your console in Safari where it is working. There have to be errors as well and check the particle.js documentation to set it up the right way.
Thats the part of particle.js where the request failes:

QUESTION
Ok some I'm making a drag and drop program using PJS on Khan Academy and here is my code:
...ANSWER
Answered 2020-Dec-21 at 03:42You're a lucky man, because I don't have to sift through all this code to know what's the issue (or else I would have helped someone else tonight, really, this is way too much code). Your problem is math. Your solution is easy.
The problemHere's what's going on: when the object is low enough to go through the floor, you invert and divide by 2 gravityStrength
. This is the exact place where things go wrong.
If the object falls more pixels than gravityStrength / 2
under the ground level, it cannot go up again, as it's position when you add the new gravityStrength
will still be under the ground. Then it will revert it's direction and half gravityStrength
again, making sure that it won't budge from this spot ever again (unless you move it by hand). It's definitively stuck.
Change this:
QUESTION
I have an array of elements to insert in a database. For each of them, I have to check their integrity (I send "Bad request" if I don't find an element):
...ANSWER
Answered 2020-Dec-05 at 00:17The error message is correct, the second parameter of reduce
is the next entry of the array being reduced, which in this case is the promises
array.
So the immediate solution is to await
the promise without trying to call it:

Answered 2020-Sep-02 at 11:25use position: fixed
instead of absolute
and use z-index of interactive div to something higher than one
and lastly don't keep anything inside the div that shows the particles..
I know Its not much understandable as you are not using React.js but the problem you are incurring would be solved with this.
so my component contains the particles.js file and all my other
