Characterizations of logarithmic advice complexity classes
(1991-12-13)
Research report
Open AccessThe complexity classes P/log and Full-P/log, corresponding to the two standard forms of logarithmic advice for polynomial time, are studied. Characterizations are found in terms of Kolmogorov-simple circuits, bounded query ... -

A Question-driven Information system adaptable via Information Extraction techniques
(2008-06-13)
Research report
Open AccessThis paper presents a system is composed by two main parts: The Information Extraction Process, which crawls the web and extracts all relevant knowledge that is then stored in the database, and the Question Processor which ... -
A topological comparison of surface extraction algorithms
(2021-10-22)
Research report
Open AccessIn many application areas, it is useful to convert the discrete information stored in the nodes of a regular grid into a continuous boundary model. Isosurface extraction algorithms differ on how the discrete information ... -
End-to-End speech translation with pre-trained models and adapters: UPC at IWSLT 2021
(2021-06-28)
Research report
Open AccessThis paper describes the submission to the IWSLT 2021 offline speech translation task by the UPC Machine Translation group. The task consists of building a system capable of translating English audio recordings extracted ... -
Gender bias in multilingual neural machine translation: The architecture matters
(2020-12-24)
Research report
Open AccessMultilingual Neural Machine Translation architectures mainly differ in the amount of sharing modules and parameters among languages. In this paper, and from an algorithmic perspective, we explore if the chosen architecture, ... -
1849-2016 - IEEE Standard for eXtensible Event Stream (XES) for achieving interoperability in event logs and event streams
(2016-09-22)
Research report
Restricted access - publisher's policyAbstract: A grammar for a tag-based language whose aim is to provide designers of information systems with a unified and extensible methodology for capturing systems behaviors by means of event logs and event streams is ... -

Representació del coneixement: una síntesi
(1991-11)
Research report
Open AccessEn aquesta síntesi es presenta una visió global dels principals formalismes de representació del coneixement, que s'han desenvolupat al llarg de la història de la Intel·ligència Artificial. Aquesta revisió ve precedida ... -
Adaptive logspace reducibility and parallel time
(1991-11)
Research report
Open AccessWe discuss two notions of functional oracle for logarithmic space-bounded machines, which differ in whether there is only one oracle tape for both the query and the answer or a separate tape for the answer, which can still ... -

The design of a parallel algorithm to solve the word problem for the free partially commutative groups
(1991-10-15)
Research report
Open AccessWe develop a parallel algorithm to solve the word problem for free partially commutative groups. These groups were introduced by C. Wrathall to generalize free groups. We represent the elements of these groups as a certain ...
