Homotopy Regularization for Boosting
2010 IEEE International Conference on Data Mining, 2010In this paper, we present a homotopy regularization algorithm for boosting. We introduce a regularization term with adaptive weight into the boosting framework and compose a homotopy objective function. Optimization of this objective approximately composes a solution path for the regularized boosting.

Homotopy nilpotency in p-regular loop spaces
Mathematische Zeitschrift, 2008The authors study the following problem: how far from being homotopy commutative is a loop space having the homotopy type of the \(p\)-completion of a product of a finite numbers of spheres. In particular, they determine the homotopy nilpotency explicitly for a \(p\)-localized compact simply connected simple Lie group and for an exotic \(p\)-compact ...

Regular Homotopies of Branched Immersions
Journal of the London Mathematical Society, 1986The branched immersions of \textit{R. D. Gulliver II}, \textit{R. Osserman} and \textit{H. L. Royden} [Am. J. Math. 95, 750-812 (1973; Zbl 0295.53002)] are discussed in the spirit of immersion theory. The main result is that if \(\phi\),\(\chi\) : \(M\to N\) are homotopic branched immersions of a compact surface M in a three- or four-manifold N, then ...

Computational homotopy of finite regular CW-spaces
Journal of Homotopy and Related Structures, 2013This paper describes an approach to the computational homotopy of CW-spaces. Computational advantages are obtained by considering spaces that a tessellated in the sense that the space is the union of the closure of its \(n\)-cells and all closures of the \(n\)-cell have face posets isomorphic to that of some fixed polytope.

On Regular Homotopy in Codimension 1
The Annals of Mathematics, 1966dfx: T(M) x T(N)f (x, is injective. The space Hom (M, N) of maps M N will be endowed with the C'topology p > 3. In particular, if Imm (M, N) is the space of immersions ME N, which will be endowed with the induced topology, any continuous arc A: I-n Imm (M, N) will be called a regular homotopy.

Super-resolution image reconstruction method using homotopy regularization
Multimedia Tools and Applications, 2015In this paper, we present a homotopy regularization based on fractional order total variation for image super-resolution. This regularization function of the proposed method is composed of three parts: fractional order TV regularization term, homotopy data fidelity term and traditional data fidelity.

Adaptive regularized method based on homotopy for sparse fluorescence tomography
Applied Optics, 2013Determining an appropriate regularization parameter is often challenging work because it has a narrow range and varies with problems, which is likely to lead to large reconstruction errors. In this contribution, an adaptive regularized method based on homotopy is presented for sparse fluorescence tomography reconstruction.
