چکیده

Amongst the many benefits of remote sensing techniques in disaster- or conflict-related applications, timeliness and objectivity may be most critical assets. Recently, increasing sensor quality data availability have shifted attention more towards information extraction process itself. With promising results obtained by deep learning (DL), notion arises that DL is not agnostic to input errors biases introduced, particular sample-scarce situations. The present work seeks understand influence different sample aspects propagating through network layers automated image analysis. In this paper, we broadly discuss conceptualisation such a database an early stage realisation: (1) inherited properties (quality parameters underlying as cloud cover, seasonality, etc.); (2) individual (i.e., per-sample) properties, including a. lineage provenance, b. geometric (size, orientation, shape), c. spectral features (standardized colour code); (3) context-related (arrangement Several hundred samples collected from camp settings were hand-selected annotated with computed initial stage. supervised annotation routine so thousands existing can labelled extended feature set. This should better condition subsequent tasks hybrid AI approach.

Feature learning in feature-sample networks using multi-objective optimization

Data and knowledge representation are fundamental concepts in machine learning. The quality of the representation impacts the performance of the learning model directly. Feature learning transforms or enhances raw data to structures that are effectively exploited by those models. In recent years, several works have been using complex networks for data representation and analysis. However, no fe...

Deep Asymmetric Multi-task Feature Learning

We propose Deep Asymmetric Multitask Feature Learning (Deep-AMTFL) which can learn deep representations shared across multiple tasks while effectively preventing negative transfer that may happen in the feature sharing process. Specifically, we introduce an asymmetric autoencoder term that allows predictors for the confident tasks to have high contribution to the feature learning while suppress...

Learning Multi-channel Deep Feature Representations for Face Recognition

Deep learning provides a natural way to obtain feature representations from data without relying on hand-crafted descriptors. In this paper, we propose to learn deep feature representations using unsupervised and supervised learning in a cascaded fashion to produce generically descriptive yet class specific features. The proposed method can take full advantage of the availability of large-scale...

Multi-task learning deep neural networks for speech feature denoising

Traditional automatic speech recognition (ASR) systems usually get a sharp performance drop when noise presents in speech. To make a robust ASR, we introduce a new model using the multi-task learning deep neural networks (MTL-DNN) to solve the speech denoising task in feature level. In this model, the networks are initialized by pre-training restricted Boltzmann machines (RBM) and fine-tuned by...
