論文紹介 Anomaly Detection using One-Class Neural Networks (修正版Katsuki Ohto
?
This document discusses anomaly detection using one-class neural networks (OC-NN). It begins by introducing one-class support vector machines (OC-SVM) which learn a decision boundary to distinguish normal data points from anomalies using only normal data for training. The document then presents OC-NN as an alternative, where a neural network is trained to learn a low-dimensional representation of only normal data, and anomalies are detected as points with a large reconstruction error. It evaluates OC-NN on several datasets, finding it can achieve good performance compared to OC-SVM at detecting anomalies, as measured by the area under the ROC curve metric.
This document discusses an AI assistant named YuriCat on Github and Twitter. It provides its creation year as 1990 and age as 15. It then lists its top 5 skills as AI, with the 5th being PONANZA. The document suggests the assistant has over 80 repositories on Github and over 200 followers on Twitter. It calculates its total experience points as 1000 based on experience points gained from years of experience and number of followers. The conclusion is that while the assistant has improved over time, there is still room for improvement to become a truly helpful AI.
