Iterative Feature Boosting for Explainable Speech Emotion Recognition

1 code implementation30 May 2024 Alaa Nfissi, Wassim Bouachir, Nizar Bouguila, Brian Mishara

In speech emotion recognition (SER), using predefined features without considering their practical importance may lead to high dimensional datasets, including redundant and irrelevant information.

Unlocking the Emotional States of High-Risk Suicide Callers through Speech Analysis

1 code implementation IEEE 18th International Conference on Semantic Computing (ICSC) 2024 Alaa Nfissi, Wassim Bouachir, Nizar Bouguila, Brian Mishara

In light of these challenges, we present a novel end-to-end (E2E) method for speech emotion recognition (SER) as a mean of detecting changes in emotional state, that may indicate a high risk of suicide.

Semantic Segmentation Using Transfer Learning on Fisheye Images

no code implementations International Conference on Machine Learning and Applications (ICMLA) 2023 Sneha Paul, Zachary Patterson, Nizar Bouguila

This can be attributed to the fact that the models are not designed to handle fisheye images, and the available fisheye datasets are not sufficiently large to effectively train complex models.

Automatic counting of planting microsites via local visual detection and global count estimation

no code implementations1 Nov 2023 Ahmed Zgaren, Wassim Bouachir, Nizar Bouguila

One of the main problems when planning planting operations is the difficulty in estimating the number of mounds present on a planting block, as their number may greatly vary depending on site characteristics.

DualMLP: a two-stream fusion model for 3D point cloud classification

1 code implementation The Visual Computer 2023 Sneha Paul, Zachary Patterson, Nizar Bouguila

The SparseNet, a relatively larger network, samples a small number of points from the complete point cloud, while the DenseNet, a lightweight network, takes in a larger number of points as input.

CrossMoCo: Multi-modal Momentum Contrastive Learning for Point Cloud

1 code implementation 20th Conference on Robots and Vision (CRV) 2023 Sneha Paul, Zachary Patterson, Nizar Bouguila

In this study, we introduce a novel selfsupervised method called CrossMoCo, which learns the representations of unlabelled point cloud data in a multi-modal setup that also utilizes the 2D rendered images of the point clouds.

CNN-n-GRU: end-to-end speech emotion recognition from raw waveform signal using CNNs and gated recurrent unit networks

no code implementations 21st IEEE International Conference on Machine Learning and Applications (ICMLA) 2023 Alaa Nfissi, Wassim Bouachir, Nizar Bouguila, Brian Mishara

Instead of using hand- crafted features or spectrograms, we train CNNs to recognise low-level speech representations from raw waveform, which allows the network to capture relevant narrow-band emotion characteristics.

Automatic counting of mounds on UAV images: combining instance segmentation and patch-level correction

no code implementations6 Sep 2022 Majid Nikougoftar Nategh, Ahmed Zgaren, Wassim Bouachir, Nizar Bouguila

Counting the number of mounds is generally conducted through manual field surveys by forestry workers, which is costly and prone to errors, especially for large areas.
