At least 10 people have been reported injured in an attack on an airport in Saudi Arabia's city of Jazan, near the border with Yemen. The Saudi Press Agency (SPA) said the attack on Friday evening targeted the King Abdullah Airport. Citing a Saudi-led coalition spokesman, SPA said that the projectile was fired from a drone, shattering the airport's facade windows and causing injuries. Six Saudis, three Bangladeshi nationals and one Sudanese were among those who were injured, according to the Reuters news agency. At least five of the victims suffered only minor injuries, while the conditions of the five others were not immediately known.

False data injection attacks (FDIA) are a main category of cyber-attacks threatening the security of power systems. Contrary to the detection of these attacks, less attention has been paid to identifying the attacked units of the grid. To this end, this work jointly studies detecting and localizing the stealth FDIA in power grids. Exploiting the inherent graph topology of power systems as well as the spatial correlations of measurement data, this paper proposes an approach based on the graph neural network (GNN) to identify the presence and location of the FDIA. The proposed approach leverages the auto-regressive moving average (ARMA) type graph filters (GFs) which can better adapt to sharp changes in the spectral domain due to their rational type filter composition compared to the polynomial type GFs such as Chebyshev. To the best of our knowledge, this is the first work based on GNN that automatically detects and localizes FDIA in power systems. Extensive simulations and visualizations show that the proposed approach outperforms the available methods in both detection and localization of FDIA for different IEEE test systems. Thus, the targeted areas can be identified and preventive actions can be taken before the attack impacts the grid.

Deep Convolutional Neural Networks (CNN) models are one of the most popular networks in deep learning. With their large fields of application in different areas, they are extensively used in both academia and industry. CNN-based models include several exciting implementations such as early breast cancer detection or detecting developmental delays in children (e.g., autism, speech disorders, etc.). However, previous studies demonstrate that these models are subject to various adversarial attacks. Interestingly, some adversarial examples could potentially still be effective against different unknown models. This particular property is known as adversarial transferability, and prior works slightly analyzed this characteristic in a very limited application domain. In this paper, we aim to demystify the transferability threats in computer networks by studying the possibility of transferring adversarial examples. In particular, we provide the first comprehensive study which assesses the robustness of CNN-based models for computer networks against adversarial transferability. In our experiments, we consider five different attacks: (1) the Iterative Fast Gradient Method (I-FGSM), (2) the Jacobian-based Saliency Map attack (JSMA), (3) the L-BFGS attack, (4) the Projected Gradient Descent attack (PGD), and (5) the DeepFool attack. These attacks are performed against two well-known datasets: the N-BaIoT dataset and the Domain Generating Algorithms (DGA) dataset. Our results show that the transferability happens in specific use cases where the adversary can easily compromise the victim's network with very few knowledge of the targeted model.

Artificial intelligence outperforms human intelligence. It can digest data at breakneck speed and stay concentrated on a single job without being distracted. AI can forecast events in the future and utilize sensors to look around physical and virtual corners. So, why does AI get it so wrong all of the time? The algorithms that describe how artificial intelligence works are created by humans, and the processed data represents an imperfect reality.

OceanX, a team of marine biologists, media and filmmakers, embarked on a quest in 2020 to explore the depths of the Red Sea where they not only found a giant shipwreck, but a massive creature that appeared to be larger than a human. While investigating the'Pella,' which sank in November 2011, at a depth of 2,800 feet, the group spotted what they thought could be'The Giant Squid.' 'I will never forget what happened next for as long as I live,' said OceanX science program lead Mattie Rodrigue in a video taken of the discovery. 'All of a sudden, as we're looking at the bow of the shipwreck, this massive creature comes into view, takes a look at the ROV [remotely operated vehicle] and curls its entire body around the bow of the wreck.' It was not until September 2021 did the team learn that the mysterious creature was'the giant form' of the purpleback flying squid, which typically grow up to two feet long. The OceanX team traveled to the Red Sea aboard the OceanXplorer, a research vessel with a 40-ton crane to launch submersibles, towed sonar arrays and other heavy equipment down into the depths.

Elon Musk has said he is "dying" to expand beyond cars and trucks with Tesla and build an electric supersonic jet. The planes would use vertical take-off and landing (VTOL) technology to rise to a high altitude, before using battery-powered propulsion to reach speeds in excess of 1,236km/h (768mph). The polymath billionaire said the only thing stopping him from developing the next-generation aircraft is his current workload. Mr Musk currently heads two multi-billion dollar companies – SpaceX and Tesla – as well as neurotech startup Neuralink and tunnel-digging venture The Boring Company. He is also the co-founder of the artificial intelligence research laboratory OpenAI and the father of six children.

Prior work on plant species classification predominantly focuses on building models from isolated plant attributes. Hence, there is a need for tools that can assist in species identification in the natural world. We present a novel and robust two-fold approach capable of identifying trees in a real-world natural setting. Further, we leverage unlabelled data through deep semi-supervised learning and demonstrate superior performance to supervised learning. Our single-GPU implementation for feature recognition uses minimal annotated data and achieves accuracies of 93.96% and 93.11% for leaves and bark, respectively. Further, we extract feature-specific datasets of 50 species by employing this technique. Finally, our semi-supervised species classification method attains 94.04% top-5 accuracy for leaves and 83.04% top-5 accuracy for bark.

Recently, there have been tremendous research outcomes in the fields of speech recognition and natural language processing. This is due to the well-developed multi-layers deep learning paradigms such as wav2vec2.0, Wav2vecU, WavBERT, and HuBERT that provide better representation learning and high information capturing. Such paradigms run on hundreds of unlabeled data, then fine-tuned on a small dataset for specific tasks. This paper introduces a deep learning constructed emotional recognition model for Arabic speech dialogues. The developed model employs the state of the art audio representations include wav2vec2.0 and HuBERT. The experiment and performance results of our model overcome the previous known outcomes.

Molecular property prediction is one of the fastest-growing applications of deep learning with critical real-world impacts. Including 3D molecular structure as input to learned models improves their performance for many molecular tasks. However, this information is infeasible to compute at the scale required by several real-world applications. We propose pre-training a model to reason about the geometry of molecules given only their 2D molecular graphs. Using methods from self-supervised learning, we maximize the mutual information between 3D summary vectors and the representations of a Graph Neural Network (GNN) such that they contain latent 3D information. During fine-tuning on molecules with unknown geometry, the GNN still produces implicit 3D information and can use it to improve downstream tasks. We show that 3D pre-training provides significant improvements for a wide range of properties, such as a 22% average MAE reduction on eight quantum mechanical properties. Moreover, the learned representations can be effectively transferred between datasets in different molecular spaces. The understanding of molecular and quantum chemistry is a rapidly growing area for deep learning with models having direct real-world impacts in quantum chemistry (Dral, 2020), protein structure prediction (Jumper et al., 2021), materials science (Schmidt et al., 2019), and drug discovery (Stokes et al., 2020). In particular, for the task of molecular property prediction, GNNs have had great success (Yang et al., 2019). GNNs operate on the molecular graph by updating each atom's representation based on the atoms connected to it via covalent bonds. However, these models reason poorly about other important interatomic forces that depend on the atoms' relative positions in space. Previous works showed that using the atoms' 3D coordinates in space improves the accuracy of molecular property prediction (Schütt et al., 2017; Klicpera et al., 2020b; Liu et al., 2021; Klicpera et al., 2021). However, using classical molecular dynamics simulations to explicitly compute a molecule's geometry before predicting its properties is computationally intractable for many real-world applications. Even recent Machine Learning (ML) methods for conformation generation (Xu et al., 2021b; Shi et al., 2021; Ganea et al., 2021) are still too slow for large-scale applications. A GNN is pre-trained by maximizing the mutual information (MI) between its embedding of a 2D molecular graph and a representation capturing the 3D information that is produced by a separate network.
