Applications of Computational Intelligence: 4th IEEE Colombian Conference, ColCACI 2021, Virtual Event, May 2728, 2021, Revised Selected Papers (Communications in Computer and Information Science)

This book constitutes revised and extended selected papers of the 4th IEEE Colombian Conference, ColCACI 2021, which was held virtually in Colombia at the end of May 2021. The 7 full papers presented in the volume were carefully reviewed and selected from 22 submissions. The papers are organized in topical sections on biomedical applications and alternative proposals and its applications. Biomedical Applications.- Anemia Detection using a Full Embedded Mobile Application with YOLO Algorithm.- On the Use of Convolutional Neural Network Architectures for Facial Emotion Recognition.- Automated Preprocessing Pipeline in Visual Imagery Tasks.- Multilabel and Multiclass Approaches Comparison for Respiratory Sounds Classification.- Alternative Proposals and its Applications. - Weighted Hausdor Distance Loss as a Function of Dierent Metrics in Convolutional Neural Networks for Ladybird Beetle Detection.- Non-linear PCA for Feature Extraction in Extreme Precipitation Events using Remote Sensing Information.
