Efficient and effective information retrieval (IR) systems are needed to fetch a large number of relevant documents and present them based on their relevance to the input queries. Previous work reported the use of sparse and dense retrievers. Sparse retrievers offer low latency b ...

Ranking Fusion Functions in Neural Ranking Models

The Impact of Ranking Fusion Function on Neural Ranking Models with Fast Forward Indexes

The research explores the impact of rank fusion functions within the retrieve-and-rerank framework with Fast-Forward Indexes. Using the BM25 sparse model for retrieval and TCT-ColBERT dense model for semantic score computation, various rank fusion functions are experimented for t ...
In the field of machine learning (ML), the goal is to leverage algorithmic models to generate predictions, transforming raw input data into valuable insights. However, the ML pipeline, consisting of input data, models, and output data, is susceptible to various vulnerabilities an ...
Remote communication applications have become a necessity in a globalised and connectedworld exemplified by the popularity of video conferencing applications. In recent years, virtual reality (VR) remote communication applications have emerged that aim to deliver a greater sense ...
Self-tracking has expanded exponentially in an era defined by the ubiquitous presence of wearable technologies and smart devices. From health and fitness to finances and productivity, these devices empower users to delve into their quantified self (QS) through an almost infinite ...
This paper accelerates the rendering of diffusion curves using the ray tracing cores found on modern NVIDIA graphics cards using the method described by Bowers et al. [Bowers, Leahey and Wang 2011]. This method approximates the final result of the Poisson equation and in this pap ...
Artists that create mirror anamorphosis usually relies on the principle of trial-and-error and manual mathematical calculations. they have to draw a deformed image on the surface to get the desired reflected image on the mirror object. A drawing interface to make this kind of art ...
Minimalistic, low-poly images have gotten more popular in recent years. But making these low-poly images by hand can be time intensive. For this reason, a lot of research has gone into how to triangulate an image (semi-)automatically. In previous works, only constant color and bi ...
This research builds upon a previous method of vectorisation of pixel art by pixel neighbour connecting and boundary energy minimisation. The downside of the previous method is the lack of user input throughout the process and possible divergence between the results and the artis ...
Many widely used Recommender System algorithms estimate user tastes without accounting for their evolving nature. In recent years there has been a gradual increase in methods incorporating such temporal dynamics through sequential processing of user consumption histories. Some wo ...

Monitoring premature babies

This report describes the implementation of a custom streaming solution from an IP camera to a web browser. The system aims to both provide live video and Video on Demand. This will be used to monitor premature babies in incubators.
The twenty-first century has brought plentiful computational power and bandwidth to the masses and has opened up access to multimedia recording devices for everyone. With these developments, a shift in the landscape of multimedia took place: from traditional one-to-many programmi ...
