Multifaceted Hierarchical Report Identification for Non-Functional Bugs in Deep Learning Frameworks

1 code implementation4 Oct 2022 Guoming Long, Tao Chen, Georgina Cosma

Yet, given the growing number of new GitHub reports for DL frameworks, it is intrinsically difficult for developers to distinguish those that reveal non-functional bugs among the others, and assign them to the right contributor for investigation in a timely manner.

AdaBoost-CNN: An adaptive boosting algorithm for convolutional neural networks to classify multi-class imbalanced datasets using transfer learning

1 code implementation Neurocomputing 2020 Aboozar Taherkhani, Georgina Cosma, T. M. McGinnity

AdaBoost-CNN is computationally efficient, as evidenced by the fact that the training simulation time of the proposed method is 47. 33 s, which is lower than the training simulation time required for a similar AdaBoost method without transfer learning, i. e. 225. 83 s on the imbalanced dataset.
