Cellphones get notifications from different companies every day, but we do not know whether these notifications have a significant impact on customersâ behaviour. Knowing the impact of these notifications would provide useful insights to marketing strategists. Since user behaviour will determine the efficacy of push notifications, this project initially aims to build a behavioural model, which will group customers based on their web site navigation behaviour.
The aim of the project is to predict future customer demand for repeat-buying items based on available customer purchase records. However, the purchase history for a single customer may not be sufficient to base predictions on. Also, some purchase records might be missing due to sales events at competitorsâ locations. Thus, treating each customer as a replicant of the average customer and averaging inter-purchase times to predict future demand will likely be an inadequate approach.
In order to properly manage the risks associated with trading complex financial products, CIBC carries out computationally expensive calculations to properly assess their exposure to various market factors. To make these computations more feasible, it is of interest to find new, efficient and approximate mathematical formulas to compute such exposures. It is also important to complement these new formulas with rigorous justification of the resulting approximation error. Such justification will provide confidence to practitioners at CIBC who will use these formulas in the future.
"Seismocardiogram (SCG) is a signal that is captured by placing an accelerometer on the human chest. This signal captures very important timing information such as opening and closing of the heart valves. In addition to these timing information, the non-invasive nature of this signal makes it an attractive solution for remote monitoring of patients with heart conditions.
The morphology of SCG signal changes depending on different types of heart conditions and diseases. A mathematical model represents the morphology of a signal in terms of certain parameters.
Gene expression in blood is highly affected by the type and proportion blood cells. Therefore, cell composition needs to be taken into account when looking for signatures specific to a condition. The issue is that cell composition needs to be assessed on fresh blood, i.e. at time of blood collection. If this has not been done, the only way one can assess is by predicting it using a methodology suggested in this proposal. Therefore, if blood cell count is not available, the cell composition can be inferred from existing next generation sequencing data sets.
Over the last few years, the data revolution occurred with the emergence of Big data. In medical field, the term big data refers to large databases in terms of patients and/or information from varied sources. Nevertheless, heterogeneity is encountered in this kind of data. Indeed, data arise from different medical centers. Furthermore, we cant perform traditional statistical methods on these large databases: major problem are multicollinearity and overfitting. Lots of regularization methods have been proposed in order to adapt classical methods. Mittal et al.
Our objective is to develop the new technics, based on the pioneers work, especially the Qoyyimi and Zitikiss (2015) extension, which can have a good performance on measuring some kinds of relationship between students marks of subjects. In order to understand the relationship between students marks on different study subjects, many studies apply some kinds of indices, such as the Pearson correlation to measuring association between variables of interest in a variety of research areas, including education. We do some extension on this route.
Corruption is recognized as a major factor hindering the development and advancement of countries where it is prevalent. (By corruption, I specifically mean political corruption, the use of powers by government officials for illegitimate private gain [Wikipedia].) Even where the incidence of corruption is relatively low, corruption when exposed has had dramatic effects, including changes in government as the majority of voters indicated their strong disapprovalthis has been the recent history in Canada and particularly in Quebec.
New methods and tools are required to (i) provide insight into spatio-temporal climate effects concerning forests and fire events (ii) provide policy-makers with quantified estimates of fire activity under changing climate scenarios as well as well-defined historical models for seasonality and the occurrence of extremes (iii) be useful in a wide variety of modeling scenarios which investigate extremes and climate change effects (iv) be disseminated broadly and hence provide forest researchers with key information on climate effects (v) provide substantial interdisciplinary expertise to the st
As online communication among children and young adults grows in popularity, concerns about online safety are receiving vast attention. The Two Hat Security (2HS) company has a rule-based filtering system to detect malicious chat messages and identify abusive users. The proposed project will improve the predictions of the trustworthiness (trust-level) of the users which can change over time and also influences what users are allowed to say in chat messages.
