Knows What It Knows: A Framework For Self-Aware Learning
Lihong Li
Video in druga učna gradiva
Oznake: computer science;machine learning
We introduce a learning framework that combines elements of the well-known PAC and mistake-bound models. The KWIK (knows what it knows) framework was designed particularly for its utility in learning settings where active exploration can impact the training examples the learner is exposed to, as is ...

Unbiased Offline Evaluation of Contextual-bandit-based News Article Recommendation Algorithms
Lihong Li
Video in druga učna gradiva
Oznake: computer science;web mining
Contextual bandit algorithms have become popular for online recommendation systems such as Digg, Yahoo! Buzz, and news recommendation in general. Offline evaluation of the effectiveness of new algorithms in these applications is critical for protecting online user experiences but very challenging du ...

The Online Discovery Problem and Its Application to Lifelong Reinforcement Learning
Lihong Li
Video in druga učna gradiva
Oznake: computer science;machine learning;artificial intelligence;social sciences;psychology;economics;medicine;neuroscience;technology;engineering;electrical engineering;control engineering
We study lifelong reinforcement learning where the agent extracts knowledge from solving a sequence of tasks to speed learning in future ones. We first formulate and study a related online discovery problem, which can be of independent interest, and propose an optimal algorithm with matching upper ...

ǂA ǂspider mating plug functions to protect sperm
He Jiang, Yongjia Zhan, Qingqing Wu, Huitao Zhang, Matjaž Kuntner, Lihong Tu
Izvirni znanstveni članek
Oznake: spiders;mating strategies;mating plugs;sperm protection mechanism;
Mating plugs in animals are ubiquitous and are commonly interpreted to be products of mating strategies. In spiders, however, mating plugs may also take on functions beyond female remating prevention. Due to the vagaries of female genital (spermathecal) anatomy, most spiders face the problem of havi ...

Introduction: It is generally thought that mating plugs, where present, impede or reduce the possibilities of female subsequent mating. Behavioral studies on numerous spiders, where mating plugs are common, have generally supported this function. However, mating plugs in spiders could plausibly serv ...

Comparative morphology refines the conventional model of spider reproduction
Yongjia Zhan, He Jiang, Qingqing Wu, Huitao Zhang, Zishang Bai, Matjaž Kuntner, Lihong Tu
Izvirni znanstveni članek
Oznake: spiders;comparative anatomy;genital anatomy;
Our understanding of spider reproductive biology is hampered by the vast anatomical diversity and difficulties associated with its study. Although authors agree on the two general types of female spider genitalia, haplogyne (plesiomorphic) and entelegyne (apomorphic), our understanding of variation ...
