Rethinking Detection Based Table Structure Recognition for Visually Rich Document Images

1 code implementation1 Dec 2023 Bin Xiao, Murat Simsek, Burak Kantarci, Ala Abu Alkheir

However, existing detection-based models usually cannot perform as well as other types of solutions regarding cell-level TSR metrics, such as TEDS, and the underlying reasons limiting the performance of these models on the TSR task are also not well-explored.

Multidomain transformer-based deep learning for early detection of network intrusion

no code implementations3 Sep 2023 Jinxin Liu, Murat Simsek, Michele Nogueira, Burak Kantarci

Timely response of Network Intrusion Detection Systems (NIDS) is constrained by the flow generation process which requires accumulation of network packets.

Efficient Information Sharing in ICT Supply Chain Social Network via Table Structure Recognition

no code implementations3 Nov 2022 Bin Xiao, Yakup Akkaya, Murat Simsek, Burak Kantarci, Ala Abu Alkheir

Table Structure Recognition (TSR) aims to represent tables with complex structures in a machine-interpretable format so that the tabular data can be processed automatically.

Handling big tabular data of ICT supply chains: a multi-task, machine-interpretable approach

no code implementations11 Aug 2022 Bin Xiao, Murat Simsek, Burak Kantarci, Ala Abu Alkheir

To transform the tabular data in electronic documents into a machine-interpretable format and provide layout and semantic information for information extraction and interpretation, we define a Table Structure Recognition (TSR) task and a Table Cell Type Classification (CTC) task.

Table Structure Recognition with Conditional Attention

no code implementations8 Mar 2022 Bin Xiao, Murat Simsek, Burak Kantarci, Ala Abu Alkheir

Table Structure Recognition (TSR) problem aims to recognize the structure of a table and transform the unstructured tables into a structured and machine-readable format so that the tabular data can be further analysed by the down-stream tasks, such as semantic modeling and information retrieval.

Risk-Aware Fine-Grained Access Control in Cyber-Physical Contexts

no code implementations29 Aug 2021 Jinxin Liu, Murat Simsek, Burak Kantarci, Melike Erol-Kantarci, Andrew Malton, Andrew Walenstein

The risk levels are associated with access control decisions recommended by a security policy.

Federated Learning-Based Risk-Aware Decision toMitigate Fake Task Impacts on CrowdsensingPlatforms

no code implementations4 Jan 2021 Zhiyan Chen, Murat Simsek, Burak Kantarci

Loss measurement considers the lost task values with respect to misclassification, where the final decision utilizes a risk-aware approach where the risk is formulated as a function of the utility loss.
