Benign Overfitting in Multiclass Classification: All Roads Lead to Interpolation [article]

Ke Wang, Vidya Muthukumar, Christos Thrampoulidis
2022 arXiv   pre-print
Motivated by this discrepancy, we study benign overfitting in multiclass linear classification.  ...  The literature on "benign overfitting" in overparameterized models has been mostly restricted to regression or binary classification; however, modern machine learning operates in the multiclass setting  ...  extent the phenomena of benign overfitting and double descent [BHMM19, GJS + 20] can be proven to occur in classification tasks.  ...

Network Attack Detection Method of the Cyber-Physical Power System Based on Ensemble Learning

Jie Cao, Da Wang, Qi-Ming Wang, Xing-Liang Yuan, Kai Wang, Chin-Ling Chen
2022 Applied Sciences  
Network attack, in addition to faults, becomes an important factor restricting the stable operation of the power system.  ...  At the same time, in the process of gradient boost, the focal loss was introduced to optimize the attention weight of the classifier to the misclassified samples, thus improving the network attack detection  ...  may lead to high rates of false alarms.  ...

Identifying and Exploiting Structures for Reliable Deep Learning [article]

Amartya Sanyal
2021 arXiv   pre-print
To do this, we identify structures in deep neural networks that can be exploited to mitigate the above causes of unreliability of deep learning algorithms.  ...  However, as recent works point out, these systems suffer from several issues that make them unreliable for use in the real world, including vulnerability to adversarial attacks (Szegedy et al. [248]),  ...  blow up, a phenomenon referred to as benign overfitting.  ...

From Dependence to Causation [article]

David Lopez-Paz
2016 arXiv   pre-print
Second, we build on this framework to interpret the problem of causal inference as the task of distribution classification, yielding a family of novel causal inference algorithms.  ...  But, currently available causal inference algorithms operate in specific regimes, and rely on assumptions that are difficult to verify in practice.  ...  Naïvely, one could extend the framework presented in Section 7.2 from the binary classification of 2-dimensional distributions to the multiclass classification of d-dimensional distributions.  ...
