This paper addresses the automated identification of violent acts from CCTV video streams using a Deep Learning model under constrained resources. While this process typically involves a powerful setup, it is useful to accelerate the training and get accurate results using more modest computational resources that would bring automatic recognition of violent acts closer to common surveillance resources. Our results provide 94.98% accuracy, on par with the state-of-the-art, but at a fraction of the training time. This translates into lower energy requirements and allows a broader deployment on large scale (urban) autonomous surveillance networks while providing an increased privacy towards citizens and lower chances of abuse from authorities.

Brand logo recognition can be viewed as identification and classification task. It finds many usages such as market discovery, target advertising, etc. The number of logos growth every year and logo itself can appear in vast variety of contexts, therefore we propose a two-step few-shot framework. We describe a novel combination of universal logo detector and few-shot classifier. The logo detector is based on YOLOv5 and is used to find the areas on the image where logos are located. With this state-of-the-art single-stage object detector we achieved higher precision than similar double-stage solutions. To classify detected logos we propose few-shot classifier which consists of ensemble of pretrained feature extractors and fine-tuned head.

The ability to explain the reasons for one’s decisions to others is an important aspect of being human intelligence. We will look at the explainability aspects of the deep learning models, which are most frequently used in medical image processing tasks. The Explainability of machine learning models in medicine is essential for understanding how the particular ML model works and how it solves the problems it was designed for. The work presented in this paper focuses on the classification of lung CT scans for the detection of COVID-19 patients. We used CNN and DenseNet models for the classification and explored the application of selected visual explainability techniques to provide insight into how the model works when processing the images.

Today, successful companies are all placing a strong emphasis on corporate social responsibility: they are involved in activities and support causes that serve the interests of a community. The emergence of a group of responsible consumers’ is not new, who place great emphasis on buying environmentally responsible and ethical products and who also value transparent communication from companies. In our quantitative methodological research, we investigated whether there is a correlation between social activism and the purchase of ethical products, and which consumer groups are active buyers of ethical products. Our results confirmed both our hypotheses: we have shown that this attitude is reflected in consumer behaviour and could contribute to increasing social responsibility activity in the future.

Digital pathology has many advantages, so the need for digitizing already existing archives naturally arises. However, the fact that there is no standard way of storing pathology archives makes it difficult to provide an automated solution. In this paper, we tackle this problem with a robotic system, which uses a deep convolutional neural network and traditional image processing methods to automatically detect and localize the pathology samples and perform pick and place to organize the samples in a rack that can be directly inserted into the whole slide imaging (WSI) scanner. We were able to achieve a 90% success rate for the pick and place process. This paper introduces the hardware setup and software components that we used for our system and briefly explains the detection procedure.

In this paper the creation of poly(styrene-b-isobutylene-b-styrene) triblock copolymer (SIBS) fiber creation with centrifugal spinning is discussed. The centrifugal spinning procedure was tested at various concentrations, rotation speeds, and needle inner diameters (ID). At the most stable condition of 25 wt% and ID = 0.55 mm needle, fibers with 4.75.3 $mu$m average diameter were acquired. Electrospinning of SIBS with polyethylene glycol was also carried out for the sake of comparison, which yielded beaded fibers at the given conditions. The productivity of centrifugal spinning was roughly two orders of magnitude higher than that of the electrospinning. The measured water contact angle on these fiber mats was 133-135°, demonstrating a highly hydrophobic property. Contact angle experiments with sunflower oil showed perfect wetting, highlighting the potential for SIBS fiber mats to be used in the separation of oil from water.

Smart agriculture takes advantage of modern computational approaches that vary from IoT, cloud computing, and artificial intelligence. The primary aim is to assist the farming process. Pest detection is one of the objectives within the area of smart agriculture. It is mainly solved by computer vision approaches, usually combined with machine learning (ML) algorithms. In this paper, we propose a solution for detecting Arion rufus snails that have emerged in Central Europe and are one of the most prolific threats to agriculture in that place. Practical experiments reveal that our method is helpful in this real-world application and opens several future challenges and lines of research.

Myocarditis occurs when the heart muscle becomes inflamed and inflammation occurs when your body’s immune system responds to infections. It can be diagnosed using cardiac magnetic resonance image (MRI), a non-invasive imaging technique with the possibility of operator bias. This paper proposes a hybrid method of deep reinforcement learning-based algorithms and meta-heuristics algorithms. A mutual learning-based artificial bee colony (ML-ABC) is employed for initial weight, which adjusts the candidate food source generated with the higher fitness between two individuals determined by a mutual learning factor. Moreover, a sequential decision-making process investigates the imbalanced classification issue, in which a convolutional neural network (CNN) is used as the foundation for policy architecture. At first, initial weights are produced using the ML-ABC algorithm. After that, the agent receives a sample at each phase and classifies it, obtaining environmental rewards. The minority class receives more rewards than the majority class. Eventually, the agent discovers an ideal strategy with the aid of a specific reward function and a beneficial learning environment. We evaluate our proposed approach on the Z-Alizadeh Sani myocarditis dataset based on standard criteria and demonstrate that the proposed method gives superior myocarditis diagnosis performance.
