• Exploring Impact of Requirements Engineering on Other IT Project Areas – Case Study

  Publikacja

  • A. Jarzębowicz
  • K. Poniatowska

  - Computer Science - Rok 2020

  Requirements Engineering (RE) is recognized as one of the most important (yet difficult) areas of software engineering that has a significant impact on other areas of IT projects and their final outcomes. Empirical studies investigating this impact are hard to conduct, mainly due to the great effort required. It is thus difficult for both researchers and industry practitioners to make evidence-based evaluations about how decisions...

• From Linear Classifier to Convolutional Neural Network for Hand Pose Recognition

  Publikacja

  • P. Rościszewski

  - Computer Science - Rok 2017

  Recently gathered image datasets and the new capabilities of high-performance computing systems have allowed developing new artificial neural network models and training algorithms. Using the new machine learning models, computer vision tasks can be accomplished based on the raw values of image pixels instead of specific features. The principle of operation of deep neural networks resembles more and more what we believe to be happening...

• Using Redis supported by NVRAM in HPC applications

  Publikacja

  • A. Malinowski

  - Computer Science - Rok 2017

  Nowadays, the efficiency of storage systems is a bottleneck in many modern HPC clusters. High performance in the traditional approach – processing using files – is often difficult to obtain because of a model’s complexity and its read/write patterns. An alternative approach is to apply a key-value database, which usually has low latency and scales well. On the other hand, many key-value stores suffer from a limitation of memory...
