Question 1

I would like to delve into writing in a more scientific way to define my problems. My though is that it will help me see more similarities between problems faster. Question Hence, I would like to ...

Question 2

There is this paper in which HIV is modelled using cellular automaton. I am trying to replicate this work but I am not getting the same results as the authors. In this paper the authors describe the ...

Question 3

I'm currently studying formal methods in software engineering related to state machines, specifically Mealy machines. This made me wonder how relevant Mealy machines really are for practical ...

Question 4

I am looking for an efficient CNF encoding of the following situation: I have sets of boolean literals $A = \{ a_1, \ldots, a_m \}$, $B = \{ b_1,\ldots, b_n \}$ and subsets $B_1, \ldots, B_m$, where ...

Question 5

So I found another discussion regarding this, but the answers did not fully separate the differenced between SID and ML. Hopefully a discussion here can shed some light on some larger differences both ...

Question 6

I am fitting different 2D geometric transformations by least-squares. For instance quadratic, $$\begin{cases}a'x^2+b'xy+c'y^2+d'x+e'y+f'=X\\a''x^2+b''xy+c''y^2+d''x+e''y+f''=Y\end{cases}$$ which is ...

Question 7

Why there is a sigma in the denominator of equation (8) in the picture? suppose we have n tasks and m fog nodes.

Question 8

I have a dataset with 9912 images, what is the best way to train them based on the pixels and features of the images to be able to predict a continuous target ranging from 1 to 100? The goal is to ...

Question 9

Suppose I have the following Petri net: I wonder whether it is possible to model an inverse relationship between $p2$ and $p3$. Basically what I want to achieve is to make either $t1$ or $t2$ ...

Question 10

I am doing a prediction assignment as part of a machine learning course using loans data. I have just done some exploratory data analysis on my dataset of just over 9000 rows. There are 11 variables ...

Question 11

I am implementing a mathematic model for predicting the congestion of 802.15.4 network based on the paper: Performance analysis of IEEE 802.15.4 non-beacon mode with the unslotted CSMA/CA Based on the ...

Question 12

First, let's start with the description of the problem in dimension 1: Let $T_0$ be a space with $n$ nodes organized in a tree structure, with $m$ of those nodes defined as target nodes. In this space,...

Question 13

I am currently studying the roofline model. Wikipedia [2] shows the following example graph: The diagonal line shows $\beta * I$. But I do not understand why this line does not go through the zero ...

Question 14

Say I have an object which I pass to a method, and the method returns that same object, just mutated. So it goes like this: ...

Question 15

I am working on the base of a language model, and am wondering how to represent the base type, which is a type Type. I have heard of an "infinite chain of ...
