Baggage screening in airports is a cornerstone in airport security measures. The advent of computer vision technologies in recent years has led to the development of several automated systems for identifying security threats in baggage scans. However, existing methods struggle to adapt to new threat categories when faced with a scarcity of data samples, and the rapid emergence of new threats. Hence, in this paper, we propose a novel CLIP-driven few-shot framework (CLIFS) to explore the potential of multi-modality using text-image fusion through contrastive learning to learn relevant contextual features for recognizing security threats with limited samples. By integrating features from GPT-4 generated captions with image features, CLIFS leverages both visual and textual data to significantly improve threat classification performance with limited samples in a few-shot learning context. Our proposed CLIFS was rigorously tested on the SIXray public available baggage X-ray dataset, where it outperformed state-of-the-art by 31.3% in accuracy and 28.40% in F1-score for the challenging 5-shots scenario, demonstrating its robustness and effectiveness in classifying threats from limited data samples.

In the field of medical diagnosis, the early detection of the cancer cells in the Lung is crucial challenge. The lung cancer is considered as the leading cancer in the worldwide for the death rates, effective and accurate detection in the early stage is essential. To address this, deep learning techniques are deployed in the recent year but not getting the promising results in the analysis of image diagnosis. In this paper, we proposed a novel approach for lung cancer detection utilizing the AlexNet convolutional neural network architecture. The network model is trained with a large dataset by learning the discriminative features indicating the presence of lung cancer. Preprocessing techniques such as data augmentation and normalization are employed to enhance model generalization and performance. The trained model achieves an impressive accuracy of 95% in detecting lung cancer, demonstrating its efficacy in clinical applications. Furthermore, the model's performance is evaluated through rigorous validation procedures, including cross-validation and testing on an independent dataset, ensuring robustness and reliability. The proposed deep learning-based approach holds great potential for early detection of lung cancer, thereby facilitating timely interventions and improving patient outcomes.

The safety validation of AI and ML-basedsystems is challenging, as (i) analytical validation needs to include the interaction with a complex and stochastic physical environment and (ii) empirical validation needs to observe very long time-horizons to get enough "statistical signal" for the typically very low safety-related incident rate. This paper proposes an approach that amplifies the empirical evidence by introducing a handicap that reduces the system performance-making safety-related failures empirically more visible in a controlled environment-and gradually removing the handicap so that the convergence to the final incident rate can be estimated. Two numerical case studies are used to support and exemplify the approach.

Single-domain generalization (SDG) can efficiently enhance model generalization while avoiding high annotation costs and privacy concerns. However, existing SDG methods are mainly based on data manipulation and meta-learning, which are not efficient enough due to the limited generalization performance and complex inference. In response to these challenges, we present a novel single domain-invariant representation learning approach for medical image segmentation, called IRLSG, with two appealing designs: (1) A Classscale Photo-metric Augmentation is first proposed to simulate unseen target domain that is sufficient in diversity and informativeness. After that, a Dual-Consistency Framework is further designed to constrain the consistency of intermediate features and segmentation results between the original and the augmented images, which helps to explore the domain-invariant representation. (2) A simple and effective Style Feature Whitening is designed to decouple and remove the domain-specific style from higher-order covariance statistics, which can further improve the modeling and generalization capability of the network. Experimental results on different benchmarks demonstrate that our IRLSG outperforms the current state-of-the-art methods in tackling single-domain generalization.
