Story Recommender

An abundance of choice presents users of many online and mobile platforms. Sorting through this to find desirable content is a challenge for users. To assist with this challenge and increase user interaction it is common to implement a recommendation system that can predict what kind of content a user will or will not be interested in. Wattpad uses such a recommendation system to connect users with stories. The research project will seek to identify relevant factors which can be used to improve the quality of recommendations given thereby building a stronger reader community. With millions of titles available to users, having a robust and trustworthy recommendation system is seen as crucial to Wattpad’s business.

Open-Source Software for Causal Transportability Analysis

Randomized clinical trials (RCTs) are considered the gold standard due to their excellent internal validity results and are a vital tool for evidence-informed global health policymaking. However, the external validity, which results from the uniqueness of low- and middle-income countries (LMICs) in healthcare, culture, and demography, significantly hampers the value of RCTs in these regions. This dilemma can be addressed with a causal inference framework called Transportability analysis, which accounts for effect modifiers that differ between the study population and target population and aim to achieve the extension (transportation) of RCT findings.
Our primary objective is to develop a software package based on R language to adopt a subgroup analysis method called Network meta-interpolation (NMI) to impute the missing values in the cells for the original study and/or target study with aggregate data. With the enriched data, we will consider various indirect treatment comparisons (ITC) to assess effect modifications in meta-analyses of aggregate data.
Our secondary objective is to complete an interactive web interface so future researchers and policymakers can use the proposed model easily during decision-making.

Zome constructibility and the omnitruncated dodecaplex

On January 25th 2019, Benoit Charbonneau and a team of volunteers attempted to construct a three-dimensional shadow of the omnitruncated dodecaplex, a four-dimensional geometric shape, built using Zometool pieces. Over the course of 14 hours, volunteers built and supported the prototype structure, which was ultimately disassembled as it could not support its own weight.

Building up on previous work of Prof Charbonneau and Spencer Whitehead, the intern will work with Prof Charbonneau to study polytopes in higher dimensions and their projections, and when projections are Zome constructible. When they are and are quite large, like the omnitruncated dodecaplex, one would need to determine how to break up the construction so that the model supports itself and doesn’t collapse. During this project, the intern will study complex geometrical structures, implement the library for their modelling, and analyze physical forces so that the constructed model is stable.

Processus d’Influence de l’IA en art (PriiArt)

La diffusion à grande échelle des IA génératives (GenIA) a levé les barrières à l’entrée de l’art. Alors que certains artistes s’opposent à l’usage des GenAI en art d’autres les considèrent plutôt comme des outils permettant d’optimiser voire d’augmenter leurs capacités créatives. Ces tensions sont donc constitutives de ce qu’est le processus de création : À quel degré une agentivité humaine doit être maintenue pour considérer une oeuvre comme humaine, voire artistique? Quelle part du processus artistique est évacuée si une partie est déléguée à une machine qui n’a ni pas de « conscience » des matériaux qu’elle combine? En somme, comment les outils et les technologies basés sur l’IA influencent-ils le processus de création en art? En partant d’une perspective dynamique et processuelle de la création artistique, cette recherche a pour objectifs : 1) de relever les modalités d’interaction entre les artistes et les IA et leurs influences sur le processus créatif; 2) d’explorer ces influences dans les relations dynamiques entre les acteurs, les productions, les actions, les auditoires et les ressources disponibles.

Créativité et protagonisme Jupaú : Stratégies contemporaines de lutte et de résistance au sein d’un monde non-autochtone

Pour la communauté Jupaú, située au Brésil dans l’État de Rondônia, le recul de la frontière de l’Amazonie au profit d’acteurs allochtones locaux, nationaux ou internationaux est une réalité qui définit leur quotidien, aussi bien en termes de destruction environnementale qu’en termes de bris des relations qui y sont entretenues. Par la reprise du narratif de leur existence, des mouvements politiques naissent et insufflent un espoir vers une réconciliation, un respect mutuel et une ouverture d’esprit. Mon projet de recherche vise à comprendre les stratégies déployées et les processus de construction, de sélection et de vulgarisation du discours politique pour un public d’une ontologie autre chez les Jupaú, à témoigner de la créativité discursive au coeur des revendications territoriales autochtones, à approfondir nos connaissances sur les relations entre les entités animales et de la nature qui sont mobilisées dans ces discours et à comprendre comment cette diplomatie ontologique s’inscrit dans un contexte de survivance et de revendication de l’altérité et par quels moyens elle tente de construire des ponts entre des mondes profondément différents.

Enhanced AI Decision Support Module

AI Decision Support Module: An enhanced AI Decision Support Module aimed at streamlining the surgical review process through the identification of suspicious excision margins within medical imaging. Building upon an existing AI framework, which utilizes labeled data for the identification of potentially problematic regions, this project seeks to improve the model’s accuracy and reliability. The key responsibilities involve increasing the training dataset via data augmentation techniques and the development of a new AI model. The expected outcome is a model that demonstrates superior evaluation metrics, including F1 score and AUPRC, on blinded test datasets, thereby facilitating a more efficient and accurate surgical planning and review process.

Word Representation Learning for Detecting Malicious Chat Messages

Communicating with peers online is an increasingly popular activity for children and teenagers, which has led to growing concerns about bullying and other forms of malicious behaviour in online chat rooms and virtual worlds. Although some online forums are patrolled by human moderators, the amount of text being generated is typically too large even for a dedicated team of humans to process. This research project will adapt machine learning techniques for the task of automatically detecting and filtering malicious messages in online chat rooms and virtual worlds. The partner organization, Two Hat Security, provides custom chat filtering as a web service, with the goal of keeping kids safe online. The expected benefits of this internship to Two Hat Security are an improvement in the accuracy of its chat filtering system, as well as more efficient and effective customization of filters for the different virtual worlds that it monitors on behalf of its clients.
