QUESTION
I'm trying to apply a PCA dimensionality reduction to a dataset that it's 684 x 1800 (observations x features). I want to reduce the amount of features. When I perfom the PCA, it tells me that to obtain the 100% of variance explained, there should be 684 features, so my data should be 684 x 684. Is it not too strange? I mean, exactly the same number...
Is there any explanation or I'm applying the PCA wrongly?
I know that there're needed 684 components to explain the whole variance cause I plot the cumulative sum of .explained_variance_ratio and it sums 1 with 684 components. And also because of the code below.
My code is basically:
...ANSWER
Answered 2020-Dec-13 at 21:23You are using PCA correctly, and this is expected behavior. The explanation for this is connected with the underlying maths behind PCA, and it certainly is not a coincidence that 100% of the variance would be explained with 684 components, which is the number of observations.
There is this theorem in algebra that tells you that if you have a matrix A of dimensions (n, m), then rank(A) <= min(n, m). In your case, the rank of your data matrix is at most 684, which is the number of observations. Why is this relevant? Because this tells you that essentially, you could rewrite your data in such a way that at most 684 of your features would be linearly independent, meaning that all remaining features would be linear combinations of the others. In this new space, you could therefore keep all information about your sample with no more than 684 features. This is also what the PCA does.
To sum it up, what you observed is just a mathematical property of the PCA decomposition.
QUESTION
I am trying to show the history of commits in my git branches in a shape of a tree using the following command:
...ANSWER
Answered 2020-Sep-23 at 10:15From graph we can see following history:
- a3dc99a - last pushed
master - 7b66735 - branched out
sidebranchwith 2 commits - 69224a7 - current state of
local master(probably not pushed) - 32f78f1 - branched out
serendipitybranch from local master with 2 commits on top of this branch
So serendipity is for sure a separate branch which just shares the same history with master up to 69224a7.
UPDATE: In response to your edit I combined your screenshots and added red line to show that below line the history is the same:
You can see clearly here that serendipity and master share the same history and serendipity has additional 2 new commits.

Dict comprehension with if-else condition does not seem to be using the if block at all. It always goes to the else block even when it should not.
I am trying to use dict comprehension with if condition in python to determine the number of occurrences of characters in a string. However, the if condition never seems to be satisfied (when it really should be). Only the else condition seems to be satisfied
...ANSWER
Answered 2019-May-30 at 02:42letter_count_map isn't assigned its new value until after the dict comprehension is fully evaluated. Before that happens, it's just the empty dict, and so nothing will be in its keys(). What you're trying to do should instead be done with a loop instead of a comprehension:
QUESTION
I am using a polaroid image gallery plugin. The way it works, the polaroid images are scattered in a div and it has some circle nav buttons at the bottom that can be clicked to make the selected image active and moves it to the middle.
Instead of having circle nav buttons for selecting each image, I wanted to use prev/next buttons (this way it won't show 20+ circle nav icons when the gallery has more than 20 photos).
I was able to add some prev/next buttons and get them working, but there is one slight issue I cannot figure out. When the gallery loads, if you select the prev/next buttons, the gallery works as intended, it will switch the photos as necessary when the buttons are clicked. However, if the user clicks anywhere in the gallery (not on the buttons) it will shuffle all of the photos (it should not shuffle), then once a user does this, the prev/next buttons no longer work until the page is refreshed.
I am still learning jQuery/js and I cannot figure out what is causing this. I need to restrict the shuffling and selecting of the photos only when the prev/next buttons are selected because if a user accidentally clicks anywhere in the gallery, the buttons break.
I created a jsfiddle here.
The html is pretty straight forward, here is an example with the prev/next buttons I added:
...ANSWER
Answered 2018-Sep-08 at 00:28I read your code and I found out that the biggest problem when you put photostack-start class is that every time you click on photostack stage you schuffle your photos twice: once in _photoShow function and once in open function (open function is triggered every time). To resolve your problem, a solution could be to stop one schuffled action. To do this I created a variable and I put it in open function:

I am wondering if it is possible to add images to the random generator so that when one clicks the button, a movie title AND a picture from the movie is displayed.

Answered 2017-Nov-20 at 02:46Just make it into a two dimensional array, then something like this should work.
QUESTION
I am trying to add images to my random array. Basically the idea is this random generator tells you what movie you should watch and I am trying to figure out how to add images of the move underneath the title. I think possibly the best way might be to create a second array with image urls, and append them to the existing array using + and brackets. I just am not sure how to get the script to load the images. Here is my codepen: https://codepen.io/McComb/pen/qVPOQO

Answered 2017-Nov-19 at 00:52The easiest way to achieve what you want is to save objects as opposed to strings in your array. That way, you can create objects that have a title field and an imageUrl field like so:
