Not memorize but one may need to derive the result. Consider differentiating the matrix logarithm of a complex matrix.

Now that einsum syntax is supported in languages like Python and Julia this is more true. Before einsum syntax, it helped if the result could be written in terms of matrix operation because then one could utilise the primitives offered by

No premonition of anything bad that will happen. Just that it is considered being dismissive or disrespectful towards the abstract concept of knowledge and learning. So you say 'sorry' in some way.

Could you explain a bit more. What you say about similar objects is obviously true. However the algorithm sketch that you have in your mind is a little implicit. Could you make it more explicit. I am quite curious. I explained my thoughts i

One way to pose/(think about) the problem is that there are two finite metric spaces linked by an unknown odometry (damn you autocorrect). The problem is to recover that unknown isometry. This, like graph isometry, can be very computat

Thanks for the recommendation . Sounds like a good read.

Let's assume that monotonocity of pair-wise distances are preserved. Without knowing the details of how the paper solved the problem, my first attempt would be to find the diametrically distant pair of points in the two different embed

Fantasys felt so lazy to me. Although sometimes I do enjoy the descriptions. But there is always an escape hatch out of a trouble and one that was not foreshadowed. It is constraints that makes things interesting and especially the higher

Many of the classics were very popular and got their label later. Classics and pop culture are not necessarily at odds.

I understand your curiosity but am glad that this was posted. A Markov chain equipped with a stack is a simple yet powerful combination for text generation. I think we need reminders that simple models can often be adequate and easy to debu

I share your dismay. I grew up under dark skies and whenever I get a chance to watch the dark skies it takes my breath away. Soon we will be limited to watching starlink streaks. Internet and smart telescopes don't do it for me. For th

It's going South and then trying to close the loop from behind. It gets interrupted by land before the loop closes. Hope it makes sense.

Indeed. One of my off by one errors is a stupid hacky Monte Carlo intution for Picks theorem. I count the number of points inside. Now about the boundary points I must assign some fractional weight because they are not fully inside. What

On the other hand, if you want to compute the area of a polygon that have vertices at lattice points, you can count the number of interior points I , the number of boundary points B . Then the area A is A = I + B/2 - 1 T

I feel bad for Roger Waters now. He seems to be a sad old solitary man shouting at the clouds, though I mostly agree with him. My disagreements are about how he treated the band.

Indeed. Cutting down on annual emissions will not be accompanied by reduction in atmospheric CO2, unless the current rate of emission is lower than that of natural processes that take CO2 out of the atmosphere. That's why atmospheric C
