A Boosting Framework of Factorization Machine [PDF]
International Journal of Pattern Recognition and Artificial Intelligence, 2021 Recently, Factorization Machine (FM) has become more and more popular for recommendation systems due to its effectiveness in finding informative interactions between features. Usually, the weights for the interactions are learned as a low rank weight matrix, which is formulated as an inner product of two low rank matrices.

Cobra Venom Factor Boosts Arteriogenesis in Mice
International Journal of Molecular Sciences, 2022 Arteriogenesis, the growth of natural bypass blood vessels, can compensate for the loss of arteries caused by vascular occlusive diseases. Accordingly, it is a major goal to identify the drugs promoting this innate immune system-driven process in patients aiming to save their tissues and life. Here, we studied the impact of the Cobra venom factor (CVF),

Can the WIMP annihilation boost factor be boosted by the Sommerfeld enhancement? [PDF]
Physical Review D, 2009 We demonstrate that the Sommerfeld correction to CDM annihilations can be appreciable if even a small component of the dark matter is extremely cold. Subhalo substructure provides such a possibility given that the smallest clumps are relatively cold and contain even colder substructure due to incomplete phase space mixing.

Factorization of boosted multijet processes for threshold resummation [PDF]
Physical Review D, 2010 Explicit applications of factorization theorems for processes at hadron colliders near the hadronic endpoint have largely focused on simple final states with either no jets (e.g., Drell-Yan) or one inclusive jet (e.g., deep inelastic scattering and prompt photon production).

Primordial black hole as a source of the boost factor [PDF]
Physics Letters B, 2011 Primordial black holes (PBHs) accumulate weakly interacting massive particles (WIMPs) around them and form ultracompact minihalos (UCMHs), if the WIMP is a dominant component of the dark matter (DM). In this paper, we discuss that the UCMHs seeded by the PBHs with sub-earth mass enhance the WIMP annihilation in the present Universe and can successfully

Factorized MultiClass Boosting
CoRR, 2019 In this paper, we introduce a new approach to multiclass classification problem. We decompose the problem into a series of regression tasks, that are solved with CART trees. The proposed method works significantly faster than state-of-the-art solutions while giving the same level of model quality.

Content‐boosted matrix factorization techniques for recommender systems [PDF]
Statistical Analysis and Data Mining: The ASA Data Science Journal, 2013 Abstract Many businesses are using recommender systems for marketing outreach. Recommendation algorithms can be either based on content or driven by collaborative filtering. We study different ways to incorporate content information directly into the matrix factorization approach of collaborative filtering.

Constant current and ripple control of LED driver without electrolytic capacitor
Dianzi Jishu Yingyong, 2018 When the traditional unloaded boost-buck LED driver power supply has a high power factor, it will produce significant low-frequency ripple current. Based on the buck-boost topology, this paper presents an innovative LED drive power technology.
