Survival Tree

Survival Tree

Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Mechanistic Models: Compartment Models in Algorithms for Numerical Problem Solving

Mechanistic models play a crucial role in algorithms for numerical problem-solving, particularly in nonlinear mixed effects modeling (NMEM). These models aim to minimize specific objective functions by evaluating various parameter estimates, leading to the development of systematic algorithms. In some cases, linearization techniques approximate the model using linear equations.
In individual population analyses, different algorithms are employed, such as Cauchy's method, which uses a...

Neural Regulation

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Neural Circuits

Neural Circuits

Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

Background:

Automated machine learning (AutoML) and artificial neural networks (ANNs) are powerful AI tools.
Limited guidance exists on choosing between AutoML and ANNs, and few tools integrate both.
Combining AutoML and ANNs can leverage their respective strengths for complex tasks.

Purpose of the Study:

To introduce TPOT-NN, an extension for the TPOT AutoML software.
To explore the performance of AutoML augmented with neural network estimators (AutoML+NN).
To compare AutoML+NN with standard non-NN AutoML for binary classification tasks.

Main Methods:

Developed TPOT-NN, an extension for the tree-based AutoML software TPOT.
Evaluated TPOT-NN on public benchmark datasets for binary classification.
Compared the classification accuracy of AutoML+NN against standard tree-based AutoML.

Main Results:

TPOT-NN demonstrated effectiveness in improving classification accuracy on certain datasets.
AutoML+NN achieved comparable or superior accuracy to standard AutoML.
No loss in accuracy was observed on datasets where standard AutoML performed well.

Conclusions:

TPOT-NN is a valuable tool for enhancing AutoML capabilities with neural networks.
Preliminary guidelines for AutoML+NN analyses are provided.
Future research directions for AutoML+NN methods, particularly within TPOT, are recommended.
