  • Guillén i Fàbregas, Albert; Land, Ingmar; Martinez, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    This paper determines the range of feasible values of standard error exponents for binary-input memoryless symmetric channels of fixed capacity C and shows that extremes are attained by the binary symmetric and the binary ...
  • Scarlett, Jonathan; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    This paper considers the problem of channel coding with a given (possibly suboptimal) maximum-metric decoding rule. A cost-constrained random-coding ensemble with multiple auxiliary costs is introduced, and is shown to ...
  • Scarlett, Jonathan; Peng, Li; Merhav, Neri; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    This paper studies expurgated random-coding bounds and exponents for channel coding with a given (possibly suboptimal) decoding rule. Variations of Gallager's analysis are presented, yielding several asymptotic and ...
  • Asyhari, A. Taufiq; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    We study transmission over multiple-input multiple-output block-fading channels with imperfect channel state information (CSI) at both the transmitter and receiver. In particular, based on mismatched decoding theory for a ...
  • Espinosa-Anke, Luis; Ronzano, Francesco; Saggion, Horacio (Springer, 2015)
    Hypernym extraction is a crucial task for semantically motivated NLP tasks such as taxonomy and ontology learning, textual entailment or paraphrase identification. In this paper, we describe an approach to hypernym extraction ...
  • Tauste Campo, Adrià; Vazquez-Vilar, Gonzalo; Guillén i Fàbregas, Albert; Koch, Tobias; Martinez, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    This paper studies the random-coding exponent of joint source-channel coding for a scheme where source messages are assigned to disjoint subsets (referred to as classes), and codewords are independently generated according ...
  • Scarlett, Jonathan; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    This paper studies the second-order asymptotics of coding rates for the discrete memoryless multiple-access channel (MAC) with a fixed target error probability. Using constant-composition random coding, coded time-sharing, ...
  • Scarlett, Jonathan; Somekh-Baruch, Anelia; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    This paper studies the mismatched decoding problem for binary-input discrete memoryless channels. An example is provided for which an achievable rate based on superposition coding exceeds the Csiszár-Körner-Hui rate, thus ...
  • Vazquez-Vilar, Gonzalo; Tauste Campo, Adrià; Guillén i Fàbregas, Albert; Martinez, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Two alternative exact characterizations of the minimum error probability of Bayesian M-ary hypothesis testing are derived. The first expression corresponds to the error probability of an induced binary hypothesis test and ...
  • Scarlett, Jonathan; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    This paper studies multiuser random coding techniques for channel coding with a given (possibly suboptimal) decoding rule. For the mismatched discrete memoryless multiple-access channel, an error exponent is obtained that ...

    The vast majority of microfluidic systems are molded in poly(dimethylsiloxane) (PDMS) by soft lithography due to the favorable properties of PDMS: biocompatible, elastomeric, transparent, gas-permeable, inexpensive, and ...
  • Lazaridis, Iosif; Comas, David, 1969-; Reich, David (2016)
    We report genome-wide ancient DNA from 44 ancient Near Easterners ranging in time between ~12,000 and 1,400 bc, from Natufian hunter-gatherers to Bronze Age farmers. We show that the earliest populations of the Near East ...
  • Bonet, Blai; Geffner, Héctor (Association for the Advancement of Artificial Intelligence (AAAI), 2012)
    It has been shown recently that the complexity of belief tracking in deterministic conformant and contingent planning is exponential in a width parameter that is often bounded and small. In this work, we introduce a new ...
  • Bonet, Blai; Geffner, Héctor (Association for the Advancement of Artificial Intelligence (AAAI), 2012)
    In the presence of non-admissible heuristics, A* and other best-first algorithms can be converted into anytime optimal algorithms over OR graphs, by simply continuing the search after the first solution is found. The ...
  • Thacher, Jesse D.; Antó i Boqué, Josep Maria; Bergström, Anna (National Institute of Environmental Health Sciences, 2018)
    BACKGROUND: The role of tobacco smoke exposure in the development and persistence of asthma and rhinoconjunctivitis through childhood into adolescence is unclear. OBJECTIVES: We assessed the associations of parental smoking ...
  • Geffner, Héctor (IOS Press, 2014)
    Artificial Intelligence is a brain child of Alan Turing and his universal programmable computer. During the 1960s and 1970s, AI researchers used computers for exploring intuitions about intelligence and for writing programs ...
