... single-precision floats in the cells would fit in 4 MB. Access in reading and writing items is also faster with NumPy. Maybe you don't care that much for just a million cells, but you definitely would for a billion cells -- neither approach would fit in a 32-bit architecture, but with 64-bit build...

...on that uses hidden trs to simulate a sliding out effect by showing the tr and sliding down the div in the td below. This process worked fantastically using knockout.js when iterating over an array of these rows, because I could use <!-- ko:foreach --> around both tr elements. ...

...ced that when One Hot encoding is used on a particular data set (a matrix) and used as training data for learning algorithms, it gives significantly better results with respect to prediction accuracy, compared to using the original matrix itself as training data. How does this performance increase h...

... a bit with the dplyr-syntax. I have a data frame with different variables and one grouping variable. Now I want to calculate the mean for each column within each group, using dplyr in R. ...

...same value do not need to actually be identical. So if $a is a literal .17 and $b arrives there through a calculation it can well be that they are different, albeit both display the same value. Usually you never compare floating-point values for equality like this, you need to use a smallest accept...
