CHAPTER 8: SUPPORT VECTOR MACHINES

Vấn đề của lớp mất cân bằng đã được tích cực điều tra và vẫn còn rộng mở, nó được xử lý theo một số cách [14], bao gồm: lấy mẫu lớp thiểu số, tính toán chi phí phân loại độ nhạy [10] mà gán chi phí cao hơn để không phân loại lớp thiểu số, stratifiers lấy mẫu về các trườn[r]

Among the different one-class approaches including Sup- port Vector Machines (SVMs), Gaussian, Kmeans, Princi- pal Component Analysis (PCA), and K-Nearest Neighbor (K-NN), we found that OC-KNN and OC-Gaussian are superior to others in terms of prediction specificity as measured by thei[r]

In this way, the training examples in differ- ent classes are not treated independently any more, and the commonality among related classes can be captured via the hierarchical l[r]

In a second set of experiments, to increase the training set size, we placed all the Colon cancer data into one training set of 62 samples. We used the leave-one- out method to assess performance.
The best leave-one-out performance is 100% accuracy for the SVMs (SVM classifier trained on SVM gene[r]

The performance of the LVQ-based on-line nugget quality classification algorithm was evaluated in terms of type 1 (α) and type 2 errors (β) for cold, normal, and expulsion welds. Type 1 error (α) (known as false alarm rate) defines the probability of “rejecting” the null hypothesis, while it is true.[r]

“What other people think” has always been important factor of information for most of us during the decision-making process. Long time before the widespread of World Wide Web, we often asked our friends to recommend an auto machine, or explain t[r]

In this paper, support vector machine classification methods were applied to automatic recognition of bird species. Recog- nition was tested with two datasets previously used in this project in order to obtain references for the new methods. Results suggest that equal or better perform[r]

In general, the support vector optimization can be solved analytically only when the number of training data is very small. The worst case computational complexity for the general analytic case results from the inversion of the Hessian matrix, thus is of order N S 3 , where N S is the[r]
