I implemented the classical non-weighted converged version of HITS algorithm. I create a root set and a base set from the root set and then I applied the HITS algorithm and got the authorities and hubs scores. Then what? I am not sure what to do with this information while I rank the pages. IRead more

I have a basic understanding how operators work (bitwise, logical, unary, ternary, etc.), but I am confused how you define what the operator does so the machine knows how to treat the operator when you use it in your code base. Are operators predefined by the compiler and is there a way for me toRead more

I’m writing a neural network and am having trouble with finding the cost to weight gradient. Supposedly the gradient is given by $ \frac{\partial C}{\partial w^l_{jk}} = a^{l-1}_k \partial^l_j$ but I’m having problems with my matrix dimensions. If $ a^{l-1}$ is of dimensions $ [n^{l-1},1]$ , $ \delta^l$ is of dimensions $ [n^{l},1]$ , andRead more

Monads in category theory is defined by triples T, unit, flat⟩. class Monad t where map :: (a -> b) -> (t a -> t b) — functorial action unit :: a -> t a flat :: t (t a) -> t a class KleisliTriple t where unit :: a -> t a flatMap ::Read more

I have a variable Int a to set variable String b. if (a < 6){ b = “A”; } else if (a < 9){ b = “B”; } else if (a < 16){ b = “C”; }else{ b = “D”; } I want to optimize it like the following: array = [“A”, “B”, “C”, “D”];Read more

I’ve seen multiple things called legal in computer science (e.g. problems, solutions), and I’ve interpreted it as valid, meaningful or well-formed but what does it exactly mean and does it have a formal definition?Read more

Is the stable matching problem greedy or Dynamic ? Please anyone can give a strong explanation as i tried to find it on the net but it isn’t available.Read more

I have a list of data sets, each containing a list of key/value items. I now want to test if some of those KVs are related to each other. Related means that a KV1 always has the same value when KV2 has a specific value and KV1 changes only when KV2 changes. So they don’tRead more

In Complexity Theory and Cryptology: An Introduction to Cryptocomplexity By Jörg Rothe Proposition 6.35b gives $ $ coNP\subseteq SPP$ $ but has no proof. How to show this?Read more

I know that for standard page tables each process would have its own page table and for inverted the OS would have it. But other than this what are the main differences between a standard page table and an inverted one?Read more
