Synthetic Dataset Generation for Concept Drift Adaptation
Concept drift, a phenomenon where the statistical properties of the target variable change over time, poses a significant challenge in data stream mining. The low amount of real word datasets with concept drift make this challenge harder on many researchers. This brief proposes an approach to ge...
Unifying generative models and exact likelihood-free inference with conditional bijections
Recent work in density estimation uses a bijection $f : X \to Z$ (e.g. an invertible flow or autoregressive model) and a tractable density $p(z)$ (e.g. [[1]](https://arxiv.org/abs/1410.8516) [[2]](http://www.dmi.usherb.ca/~larocheh/projects_nade.html) [[3]](https://arxiv.org/abs/1410.6460) [[4]...

Phylogenetic tree representation in n-dimensional space
Traditional phylogenetic trees are represented as bifurcating trees, where the leaf nodes represent taxa and the internal nodes represent common ancestors. Bifurcating trees offer advantages of interpreting common ancestors as well as being widely accepted; however, this representation could lim...

Applying Supervised Machine Learning to the Fight against Online Child Sexual Abuse
Some reports of NGOs and anecdotal evidence suggest that child abuse materials (CAMs) share some characteristics extensively. They mostly take place indoor settings, victims' face or genitalia is visible and there are few visual clues about the abuser(s). For the known CAMs, there are methods...
A simple form of Rayleigh pitot tube formula
Rayleigh pitot tube formula is a very basic and commonly used formula in aerodynamics. It gives the rate of the total pressure behind a normal shock wave and the pressure of freestream at a given Mach number. Although the relation is rigorous in theory, it is difficult to understand the changing...
Backward stepwise elimination: A model-based method for nonlinear dimension reduction
In multidimensional data modeling, dimension reduction is not intuitive. Forward feature selection is usually deceptive. That is, a strongly related feature may have a small correlation coefficient (near zero) to the objective, especially when the target model is nonlinear. Therefore, we suggest...
Dermatoglyphics to predict genetic disorders
In recent times, genetic disorders have risen to be one of the significant causes of mortality. As we improve our understanding of the human genome, we see that nearly all diseases have a genetic component linked to them. Early diagnosis of these genetic diseases is crucial for successful treatm...

Applying Machine Learning to Detect Code Quality Issues
Detecting the potential problems in the code before the product is released can prevent the problems in production and lower the cost of the system operation. The automated code review tools are relying on detecting code patterns that are know to cause problems. This methods are unable to find n...
Vein Dynamics to predict the immune response and susceptibility to disorders
The immune system acts as a protective framework against the pathogenic microbes. Understanding the immune system can give us insights of how vulnerable someone is to foreign invaders. Amidst the recent events such as virus outbreaks it becomes highly advantageous if we pinpoint the individuals ...
A service to assess the quality of documentation of open source software
Could one build a service that checks the completeness and quality of documentation of an open source repository? Potentially a group could build up a set of repositories with documentation ratings, which could then be used to train a ML/DL model, which could then be used to provide the servi...
