Using Column Transformer with Mixed Types

My code comes from adapting the sample code on the page in the scikitlearn manual (scikit-learn 0.22.2) called ‘Column Transformer with Mixed Types’. The original code uses sample data from the titanic. My data comes from a pandas data file. The sample code shows how to handle just that situation anyway (just commented). My goal: […]

same Averages ie: same mean mode and median = 5

I am stuck with this question: Charlie makes different sets of five positive whole numbers. He finds there are only $4$ sets whose mean, median and mode are all equal to $3$. $1, 2, 3, 3, 6;$ $1, 3, 3, 3, 5;$ $2, 3, 3, 3, 4;$ $3, 3, 3, 3, 3;$ How many sets […]

Average of function defined on cantor set

Suppose we have $P: A\cap[0,1]\to\mathbb{R}$, where $A$ is the Cantor set. I want to define and find the average of $P$ to give a result between the infimum and supremum of $P$‘s range. Obviously we cannot use the Lebesgue measure, as the average would be zero. Instead, we need a new definition. My intuition is, […]

Encrypt with CryptoJS in JavaScript gives me different results from Java encryption

I am trying to replicate with CryptoJS an encryption done in Java using another library. The encryption’s result in Java is [111,60,-98,107,-60,5,-17,91,-52,60,-105,64,-88,31,97,-102,118,-39,-28,3,70,-12,21,-69,70,-22,-12,-91,102,-21,-88,5,82,-66,-122,34,14,-115,7,82,-55,38,-90,74,-4,62,104,104,61,-78,57,59,-51,31,84,-115,-45,-98,-87,-11,53,98,45,2,-52] and I know that this is the correct payload. So, I am replicating the same encryption with the same values but I don’t get the same array of bytes. The steps are: I […]

Count elements of order 6 in $D_3 \times S_4 \times \mathbb{Z}_4$

I need to count elements of order 6 in $D_3 \times S_4 \times \mathbb{Z}_4$. I understand that the order 6 of the elements implies that the $\mathrm{lcm}(|d_i|, |s_j|, |z_k|)=6$. That means next possible combinations of $|d_i|, |s_j|, |z_k|$: 1, 1, 6 1, 2, 6 1, 3, 6 1, 6, 6 2, 1, 6 2, 2, […]

Matplotlib | Change in plot representation when applying logarithmic scale

Given a set of points to be represented on a 3D plot (as scatter plot) I thought it would be interesting to plot the same data in 2D instead of 3D thanks to hist2d and using weights. This data has low and high values (some orders of magnitud apart) so when represented as a hist2d […]

When user writes the shortcode in the page, it generates some CSS, some HTML and some JavaScript but result is not rendered as I want I think because of active theme CSS. […]
