Bag-of-Words vs. Graph vs. Sequence in Text Classification: Questioning the Necessity of Text-Graphs and the Surprising Strength of a Wide MLP [PDF]

open access: yesAnnual Meeting of the Association for Computational Linguistics, 2021
Graph neural networks have triggered a resurgence of graph-based text classification methods, defining today’s state of the art. We show that a wide multi-layer perceptron (MLP) using a Bag-of-Words (BoW) outperforms the recent graph-based models TextGCN

Decomposing Bag of Words Histograms [PDF]

open access: yes2013 IEEE International Conference on Computer Vision, 2013
We aim to decompose a global histogram representation of an image into histograms of its associated objects and regions. This task is formulated as an optimization problem, given a set of linear classifiers, which can effectively discriminate the object categories present in the image.

Assessing the impact of bag‐of‐words versus word‐to‐vector embedding methods and dimension reduction on anomaly detection from log files

open access: yesInternational Journal of Network Management, 2023
In terms of cyber security, log files represent a rich source of information regarding the state of a computer service/system. Automating the process of summarizing log file content represents an important aid for decision‐making, especially given the 24/

Lexical Ambiguity in Political Rhetoric: Why Morality Doesn't Fit in a Bag of Words

open access: yesBritish Journal of Political Science, 2023
How do politicians use moral appeals in their rhetoric? Previous research suggests that morality plays an important role in elite communication and that the endorsement of specific values varies systematically across the ideological spectrum.
