Naïve filterbots for robust cold-start recommendations
- Proc. of the 12th ACM SIGKDD Int’l Conf
, 2006
"... The goal of a recommender system is to suggest items of interest to a user based on historical behavior of a community of users. Given detailed enough history, item-based collaborative filtering (CF) often performs as well or better than almost any other recommendation method. However, in cold-start ..."

situations—where a user, an item, or the entire system is new—simple non-personalized recommendations often fare better. We improve the scalability and performance of a previous approach to handling cold-start situations that uses filterbots, or surrogate users that rate items based only on user or item
Cold-start Active Learning with Robust Ordinal Matrix Factorization
"... We present a new matrix factorization model for rating data and a corresponding active learning strategy to address the cold-start problem. Cold-start is one of the most challenging tasks for rec-ommender systems: what to recommend with new users or items for which one has little or no data. An appr ..."

Ensemble Contextual Bandits for Personalized Recommendation
"... The cold-start problem has attracted extensive attention among various online services that provide personalized rec-ommendation. Many online vendors employ contextual ban-dit strategies to tackle the so-called exploration/exploitation dilemma rooted from the cold-start problem. However, due to high ..."

Personalized Recommendation via Parameter-Free Contextual Bandits
"... Personalized recommendation services have gained increas-ing popularity and attention in recent years as most useful information can be accessed online in real-time. Most on-line recommender systems try to address the information needs of users by virtue of both user and content informa-tion. Despit ..."

. Despite extensive recent advances, the problem of per-sonalized recommendation remains challenging for at least two reasons. First, the user and item repositories undergo frequent changes, which makes traditional recommendation algorithms ineffective. Second, the so-called cold-start prob-lem is difficult
Cross Domain Recommendation Using Vector Space Transfer Learning
"... ABSTRACT The cold start problem, frequent with recommender systems, addresses the issue in cases where we don't know enough about our users (e.g., the user hasn't rated anything yet, or there are no user activities) in that specific domain. In our paper we present a simple and robust tran ..."

Fluorine gas is produced industrially by electrolysing hydrogen fluoride in a potassium acid fluoride electrolyte. Fluorine is produced at the carbon anode, while hydrogen is produced at the mild-steel cathode. The fluorine produced has a wide range of uses, most notably in the nuclear industry where it is used to separate 235U and 238U. The South African Nuclear Energy Corporation (Necsa) is a producer of fluorine and requested an investigation into the hydrodynamics of their electrolysis cells as part of a larger national initiative to beneficiate more of South Africa’s large fluorspar deposits. Due to the extremely corrosive and toxic environment inside a typical fluorine electrolysis reactor, the fluid dynamics in the reactor are not understood well enough. The harsh conditions make detailed experimental investigation of the reactors extremely dangerous. The objective of this project is to construct a model that can accurately predict the physical processes involved in the production of fluorine gas. The results of the simulation will be compared to experimental results from tests done on a lab-scale reactor. A good correlation

Copper transporter 2 regulates the cellular accumulation and cytotoxicity of Cisplatin and
, 2009
"... Abstract Purpose: Copper transporter 2 (CTR2) is known to mediate the uptake of Cu +1 by mammalian cells. Several other Cu transporters, including the influx transporter CTR1 and the two efflux transporters ATP7A and ATP7B, also regulate sensitivity to the platinum-containing drugs. We sought to de ..."
