Animating Still Images: Folding Texture Design and Synthesis

The phenomenon of one element moving and progressively overlaying another is common in nature, such as waves swashing and backwashing, or eyelids moving over eyeballs while blinking. Folding Texture, which was proposed by Thorben, can simulate this texture “folding” visual effect in real-time without changing geometry.<br/>However, to date, no...

Exploring Stance Detection of Opinion Texts: Evaluating the Performance of a Large Language Model: Benchmarking the Performance of Stance Classification by GPT-3-Turbo

In April 2020, a Dutch research team swiftly analyzed public opinions on COVID-19 lockdown relaxations. However, due to time constraints, only a small amount of opinion data could be processed. With the surge of popularity in the field of Natural Language Processing (NLP) and the arrival of tools like ChatGPT, a number of tasks involving Large...

Automatic text-based speech overlap classification: A novel approach using Large Language Models

Meetings are the keystone of a good company. They allow for quick decision making, multiple-perspective problem solving and effective communication. However, most employees and managers have a negative view on the efficiency and quality of their meetings. High quality meetings where every participant feels equally heard and respected is crucial...

Evaluating the effectiveness of large language models in meeting summarization with transcript segmentation techniques: How well does gpt-3.5-turbo perform on meeting summarization with topic and context-length window segmentation?

Large Language Models (LLM) have brought significant performance increase on many Natural Language Processing tasks. However LLMs have not been tested for meeting summarization. This research paper examines the effectiveness of the gpt-3.5-turbo model on the meeting summarization domain. However due to input length limitations, it cannot be...

Zero-shot learning for (dis)agreement detection in meeting trancripts: Comparing latent topic models and large language models

This paper presents a novel approach to detect agreement and disagreement moments between participants in meeting transcripts without relying on labeled data. We propose a model in which disagreement detection is defined as the process of first identifying argumentative theses relevant to a given corpus of text and then classifying all phrases...

Improving on Very Large Neighborhood Search techniques in Program Synthesis

Inductive Program Synthesis (IPS) has been implemented by a two-stage search algorithm, Brute, and consequently improved upon with a Large Neighborhood Search (LNS) technique, in an algorithm named Vlute. Unmotivated values and design choices within Vlute caused limitations on the performance of IPS tasks. This research improves upon several of...

How to train your dragon: on the application of the Metropolis-Hastings algorithm for program synthesis

This paper addresses the problem of Inductive Synthesis by analysing the Metropolis-Hastings stochastic search algorithm. The goal of Inductive Synthesis is to generate programs whose intended behaviour is established through the use of input and output examples. The Metropolis-Hastings algorithm searches the set of all possible programs and...

Genetic Algorithms for Inductive Program Synthesis

VanillaGP is an Inductive Program Synthesis algorithm that takes a Genetic Algorithm (GA) approach by using its 3 components: selection, mutation, and crossover. Many different alternatives exist for these components and although this is not the only application of a GAs on the Program Synthesis domain, it has not been extensively evaluated what...

Improvements in Monte Carlo Tree Search for Inductive Program Synthesis

A recent development in program synthesis is using Monte Carlo Tree Search to traverse the search tree of possible programs in order to efficiently find a program that will successfully transform the given input to the desired output. Previous research has shown promising results as Monte Carlo Tree Search is able to escape local optima that...

Exploitation of P4 Programmable Switch Networks

P4 programmable data-planes provide operators with a flexible method to set up data-plane forwarding logic. To deploy networks with confidence, a switch's forwarding logic should correspond with its intended behavior. Programs loaded onto programmable data-planes don't necessarily go through as much testing as traditional fixed-function devices...

P4Runtime Security and Man-in-the-Middle Attacks

In software defined networking a controller can control where the data-plane routes packets to. Programmable data-planes make networks even more flexible, as the algorithms on the data-plane can be updated. The P4 programming language can be used to program data-planes, and the P4Runtime data-plane API can be used for controller to data-plane...

Corrupting P4 programs by manipulating packet data

Data planes are responsible for forwarding packets in a network. The P4 language is used for programming programmable data planes. Such data planes give more flexibility to programmers by allowing them to define how the packets should be processed. However, these data planes might also be more vulnerable to malicious attacks than traditional ...

Detection and Mitigation Mechanisms for Attacks in Programmable Data Planes

DDoS attacks are becoming more common and sophisticated. Only recently, in 2017, Google claims they have mitigated an attack which sent 2.54 Tbps of traffic to their servers. In order to prevent these attacks, more and more robust defence mechanisms need to be put in place to withstand the malicious traffic and secure the networks. Programmable...

The effect of a corrupt program on virtualized P4 programs in HyperVDP

After software defined networking (SDN) separated the control-plane from the dataplane, P4 was proposed as a solution to be able to program the data-plane. The programmable data plane (PDP) is very useful to alter the behaviour of programmable network devices. The drawback, however, is that without virtualization only one single P4 program can...
