MASTER THESIS WORK IMAGE ANALYSIS ALGORITHMS FOR FEATURE EXTRACTION IN EYE FUNDUS IMAGESHernández, Andrés G Marrugo
Feature attributions based on the Shapley value are popular for explaining machine learning models. However, their estimation is complex from both theoretical and computational standpoints. We disentangle this complexity into two main factors: the approa
For data processing, the system uses various pre-processing approaches due to the variety of data collected and different data extraction methods. To reduce the amount of post-development needed, service indicators are abstracted into generic data models. Collection and pre-processing functions are a...

Data training includes two steps, feature extraction and classification, as discussed in the following subsections. Feature extraction Different features can be extracted from the ECG signal. For example, the estimation of different peaks can be used to find the time intervals between different peaks...
FreshPRINCE is a pipeline algorithm for regression with two components: the TSFresh feature extraction algorithm that transforms the input time series into a feature vector, and then a Rotation Forest (RotF) (Rodriguez et al. 2006) estimator that builds a model and makes target predictions. The...

There are two main types of computer vision techniques adopted for wildfire detection. The first one is traditional machine learning-based methods, which are based on handcrafted feature extraction and color transformations [9,44]. However, manual feature selection and engineering take a very long ...
Hall Effect sensors, bioimpedance using an impedance electrode array or pressure tomography waveforms have also been used as substitutes for the PPG signal. Pulse wave morphology (PWM) and feature extraction in BP estimation While PTT is a good predictor of BP, it also varies with arterial ...
2.1. Overview of Feature Extraction Methods Handcrafted features and learning-based features are both adopted for feature extraction. Both globally and locally specified image features are possible for each type. The mathematical concept underlying the various feature extraction methods is illustrated in...
