Two-Stage Classifier for Campaign Negativity Detection using Axis Embeddings: A Case Study on Tweets of Political Users during 2021 Presidential Election in Iran

no code implementations31 Oct 2023 Fatemeh Rajabi, Ali Mohades

By running the best model on the rest of the tweets of 50 political users that were published one year before the election and with the help of statistical models, we find that the publication of a tweet by a candidate has nothing to do with the negativity of that tweet, and the presence of the names of political persons and political organizations in the tweet is directly related to its negativity.

Computing The Packedness of Curves

1 code implementation8 Dec 2020 Sepideh Aghamolaei, Vahideh Keikha, Mohammad Ghodsi, Ali Mohades

Assuming $L$ is the diameter of $P$ and $\delta$ is the minimum distance between points on disjoint edges of $P$, we show the approximation factor of the existing $O(\frac{\log (L/\delta)}{\epsilon}n^3)$ time algorithm is $1+\epsilon$-approximation algorithm.

An efficient approximation for point-set diameter in higher dimensions

no code implementations26 Oct 2016 Mahdi Imanparast, Seyed Naser Hashemi, Ali Mohades

In this paper, we study the problem of computing the diameter of a set of $n$ points in $d$-dimensional Euclidean space for a fixed dimension $d$, and propose a new $(1+\varepsilon)$-approximation algorithm with $O(n+ 1/\varepsilon^{d-1})$ time and $O(n)$ space, where $0 < \varepsilon\leqslant 1$.
