This publication constitutes the refereed complaints of the 20 th Annual convention on studying concept, COLT 2007, held in San Diego, CA, united states in June 2007.

The forty-one revised complete papers awarded including five articles on open difficulties and a couple of invited lectures have been rigorously reviewed and chosen from a complete of ninety two submissions. The papers disguise quite a lot of themes and are equipped in topical sections on unsupervised, semisupervised and energetic studying, statistical studying concept, inductive inference, regularized studying, kernel tools, SVM, on-line and reinforcement studying, studying algorithms and barriers on studying, dimensionality aid, different ways, and open problems.

We have uT (w − μ) > 1 − δ, 0 < w − μ 2 < ǫ w−μ 2 √ √ uT ( m(w − μ)) = Pr √ > 1 − δ, 0 < m w − μ m w−μ 2 Pr[w ∈ Y ] = Pr 2 √ <ǫ m . 4 In particular this means that there is a sequence {ζm }∞ m=1 , ζm → 0, such that 4 Σ = diag(μ1 , μ2 , . . , μn ) − μμT , the rank of Σ is n − 1, and its rows (or columns) span the (n − 1)-dimensional vector space {u ∈ Rn | u1 + u2 + · · · + un = 0}. 32 S.

Ck of partition C are uniquely determined by matrix A. To this end, we view A as the adjacency matrix of a graph G with nodes x1 , x2 , . . , xn , where nodes xp , xq are connected by an edge if and only if Ap,q = 0. Let K1 , K2 , . . , Kℓ be the connected components of G. Note that there is an edge between xp and xq only if p and q belong to the same cluster Stability of k-Means Clustering 29 in C. Thus, the connected components of G represent a refinement of partition C. Consider a fixed cluster Cj in C with center cj .

Straightforward but long calculation, starting with formula (2). See the extended version paper [1] available online. ⊓ ⊔ Lemma 7 (Weights of Clusters). Let C and D be two partitions of F . Consider the weights μ assigned to points in F . Then, either for every point in F the weight of its cluster in C is the same as the weight of its cluster in D. Or, there are two points in F , such that the weight of the cluster of the first point in C is strictly larger than in D, and the weight of the cluster of the second point in C is strictly smaller than in D.
