Optimizing Camera Configurations for Multi-View Pedestrian Detection
Jointly considering multiple camera views (multi-view) is very effective for pedestrian detection under occlusion.
Empathy Detection Using Machine Learning on Text, Audiovisual, Audio or Physiological Signals
Empathy is a social skill that indicates an individual's ability to understand others.
Adaptive Multi-head Contrastive Learning
As such, enforcing a high similarity for positive pairs and a low similarity for negative pairs may not always be achievable, and in the case of some pairs, forcing so may be detrimental to the performance.
Training with Product Digital Twins for AutoRetail Checkout
Because the digital twins individually mimic user bias, the resulting DT training set better reflects the characteristics of the target scenario and allows us to train more effective product detection and tracking models.
Pavlok-Nudge: A Feedback Mechanism for Atomic Behaviour Modification with Snoring Usecase
To this end, we design a user interface to generate an automatic feedback mechanism that integrates Pavlok and a deep learning based model to detect certain behaviours via an integrated user interface i. e. mobile or desktop application.
Glitch in the Matrix: A Large Scale Benchmark for Content Driven Audio-Visual Forgery Detection and Localization
The proposed baseline method, Boundary Aware Temporal Forgery Detection (BA-TFD), is a 3D Convolutional Neural Network-based architecture which effectively captures multimodal manipulations.

Large-scale Training Data Search for Object Re-identification
We consider a scenario where we have access to the target domain, but cannot afford on-the-fly training data annotation, and instead would like to construct an alternative training set from a large-scale data pool such that a competitive model can be obtained.
A Bag-of-Prototypes Representation for Dataset-Level Applications
The former measures how suitable a training set is for a target domain, while the latter studies how challenging a test set is for a learned model.
AMF: Adaptable Weighting Fusion with Multiple Fine-tuning for Image Classification
Fine-tuning is widely applied in image classification tasks as a transfer learning approach.
Strengthening Skeletal Action Recognizers via Leveraging Temporal Patterns
Skeleton sequences are compact and lightweight.
Deep transfer learning for image classification: a survey
We show that under this new taxonomy, many of the applications where transfer learning has been shown to be ineffective or even hinder performance are to be expected when taking into account the source and target datasets and the techniques used.
ANUBIS: Skeleton Action Recognition Dataset, Review, and Benchmark
To this end, we present a review in the form of a taxonomy on existing works of skeleton-based action recognition.
Attribute Descent: Simulating Object-Centric Datasets on the Content Level and Beyond
This article aims to use graphic engines to simulate a large number of training data that have free annotations and possibly strongly resemble to real-world data.
How to Synthesize a Large-Scale and Trainable Micro-Expression Dataset?
To this end, we develop a protocol to automatically synthesize large scale MiE training data that allow us to train improved recognition models for real-world test data.

This dynamicity is imposed on top of an already complex fitness landscape.
Feature Selection on Thermal-stress Dataset
These findings are likely to improve the accuracy of current stress recognition systems.
Exploring Biases and Prejudice of Facial Synthesis via Semantic Latent Space
Varying the proportions of male and female faces in the training data can have a substantial effect on behavior on the test data: we found that the seemingly obvious choice of 50:50 proportions was not the best for this dataset to reduce biased behavior on female faces, which was 71% unbiased as compared to our top unbiased rate of 84%.
Non-binary deep transfer learning for image classification
A model is either pre-trained or not pre-trained.

Neural Network Classifier as Mutual Information Evaluator
We give a new view of neural network classifiers with softmax and cross-entropy as mutual information evaluators.
Position-Sensing Graph Neural Networks: Proactively Learning Nodes Relative Positions
Such GNNs are incapable of learning relative positions between graph nodes within a graph.
Disentangling Noise from Images: A Flow-Based Image Denoising Neural Network
The prevalent convolutional neural network (CNN) based image denoising methods extract features of images to restore the clean ground truth, achieving high denoising accuracy.
Fusing Higher-order Features in Graph Neural Networks for Skeleton-based Action Recognition
Recent skeleton-based action recognition methods extract features from 3D joint coordinates as spatial-temporal cues, using these representations in a graph neural network for feature fusion to boost recognition performance.

Invertible Denoising Network: A Light Solution for Real Noise Removal
InvDN transforms the noisy input into a low-resolution clean image and a latent representation containing noise.
S2FGAN: Semantically Aware Interactive Sketch-to-Face Translation
Instead of constraining the translation process by using a reference image, the users can command the model to retouch the generated images by involving the semantic information in the generation process.

The personal identity information in original EEGs are transformed into disguised ones with a CycleGANbased EEG disguising model.
Analogical and Relational Reasoning with Spiking Neural Networks
To illustrate this, we first investigate the performance of our networks with supervised learning, then with unsupervised learning.

This inspired our research which explores the performance of two models from pixel transformation in frontal facial synthesis, Pix2Pix and CycleGAN.
Are Deep Neural Architectures Losing Information? Invertibility Is Indispensable
Identifying the information lossless condition for deep neural architectures is important, because tasks such as image restoration require keep the detailed information of the input data as much as possible.
A Genetic Feature Selection Based Two-stream Neural Network for Anger Veracity Recognition
For example, acted anger can be expressed when stimuli is not genuinely angry with an aim to manipulate the observer.
