Uniform deviation bounds limit the difference between a model’s expected loss and its loss on a random sample uniformly for all models in a learning problem. In this paper, we provide a novel framework to obtain uniform deviation bounds for unbounded loss functions. As a result, we obtain competitive uniform deviation bounds for k-Means clustering under weak assumptions on the underlying distri...
This study explored the relationship between students’ math ability and effort in predicting 6 grade students’ performance in the Assessment and LEarning in Knowledge Spaces (ALEKS) system. The students were clustered into four groups by Kmeans: high ability high effort, high ability low effort, low ability high effort and low ability low effort. A one-way ANOVA indicated that student’s math po...
Spaced seeds have been extensively studied in the homology search field. A spaced seed can be regarded as a very special type of hash function on k-mers, where two k-mers have the same hash value if and only if they are identical at the w (w < k) positions designated by the seed. Spaced seeds substantially increased the homology search sensitivity. It is then a natural question to ask whether t...
BP$k$ NN: $k$ -Nearest Neighbor Classifier With Pairwise Distance Metrics and Belief Function Theory
In Iran, no research has yet been performed on potassium release from feldspar in comparison with that from muscovite. The objective of this research was to compare potassium release kinetics of these minerals as influenced by organic and inorganic extractants using successive extraction method. The experiment was carried out in a completely randomized design with a factorial combination. Treat...
Let T1,...,Tn be exchangeable random variables and suppose that T{1:n} represents the ith order statistic among Ti's, i=1,...,n. ‎In this paper some expressions for the joint distribution ‎of (T{1:n},...,T{n:n}), ‎marginal distribution of T{1:n} and the joint distribution of (T{r:n},T{k:n}), 1≤ r ≤ k ≤n ‎in terms of the joint...
