Neural Architecture Search for Skin Lesion Classification
PublikacjaDeep neural networks have achieved great success in many domains. However, successful deployment of such systems is determined by proper manual selection of the neural architecture. This is a tedious and time-consuming process that requires expert knowledge. Different tasks need very different architectures to obtain satisfactory results. The group of methods called the neural architecture search (NAS) helps to find effective architecture...

The effect of transglutaminase on the properties of salmon skin-gelatin films
PublikacjaCelem pracy była enzymatyczna modyfikacja folii otrzymanych z żelatyny rybnej. Źródłem żelatyny były surowe i wędzone skóry łososia. Stwierdzono, że czas żelowania roztworu żelatyny ulegał skróceniu w obecności transglutaminazy w badanym zakresie 0,1-0,2 mg/ml. Enzymatyczne modyfikacje prowadziły do obniżenia rozpuszczalności folii, jednakże w różnym stopniu zależnym od źródła białka. Obecność DTT lub cysteiny w mieszaninie reakcyjnej...

Self-Supervised Learning to Increase the Performance of Skin Lesion Classification
PublikacjaTo successfully train a deep neural network, a large amount of human-labeled data is required. Unfortunately, in many areas, collecting and labeling data is a difficult and tedious task. Several ways have been developed to mitigate the problem associated with the shortage of data, the most common of which is transfer learning. However, in many cases, the use of transfer learning as the only remedy is insufficient. In this study,...

Reexamination of the decoherence of spin registers
PublikacjaWe revisit the decoherence process of a multiqubit register interacting with a thermal bosonic bath. We generalize the previous studies by considering not only the register’s behavior but also a part of its environment. In particular, we are interested in information flow from the register to the environment, which we describe using recently introduced multipartite quantum state structures called spectrum broadcast structures....
