Slides: https://jakubnowosad.com/agforum2025 This presentation covered three interconnected deep learning concepts appearing in spatial data science work. Graph Neural Networks (GNNs) are a deep learning architecture that represents spatial dat...

The first step in the value chain for water utilities is extracting water from natural sources, such as rivers, groundwater, oceans, or reservoirs. Water managers and the public alike are interested in knowing how much water a reservoir currently holds. This is not an easy problem to solve, as it ...

Functional analysis is useful for determining the functions of a set of interesting genes. These gene sets can be lists of genes produced from different analysis, including weighted gene co-expression network analysis (WGCNA). The freeCount FA app will help you perform functional analysis of gene sets, which can be produced ...

A simple example of overfitting Random Fourier Features

Weighted gene co-expression network analysis (WGCNA) is used to investigate the function of genes at the system-level. In a network analysis genes with similar patterns of expression are grouped together into modules. The sets of genes in these modules are co-expressed as a result of shared biological functions, pathways, tissues, ...

In a recent post I have shown that we can build linear combinations of model parameters (see here ). For example, if we have two parameter estimates, say \(X\) and \(Z\), with standard errors respectively equal to \(\sigma_X\) and \(\sigma_Z\) and a...

A common use of ROC (Receiver Operating Characteristic) curves in data science is to evaluate performance of binary classifiers. In this use case, the data set is usually a sample from a population and so the ROC curve itself is a random object. Although it is not common to have ...

Introduction To a beginner, open source can be one of the best pathways into a fulfilling tech career. It not only provides access to source codes but also connects you with a global community of people from diverse backgrounds and skill sets. ...

Generalized additive models for location, scale, and shape (GAMLSS) are popular for estimating reference equations, e.g., for lung function measurements. A recent paper claimed to 'debunk' the GAMLSS myth in this context by showing that much ...
