    In this paper, a survey of the literature of the past fifteen years involving Machine Learning (ML) algorithms applied to self organizing cellular networks is performed. In order for future networks to overcome the current limitations and address the issues of current cellular systems, it is clear that more intelligence needs to be deployed, so that a fully autonomous and flexible network can be enabled. This paper focuses on the learning perspective of Self Organizing Networks (SON) solutions and provides, not only an overview of the most common ML techniques encountered in cellular networks, but also manages to classify each paper in terms of its learning solution, while also giving some examples. The authors also classify each paper in terms of its self-organizing use-case and discuss how each proposed solution performed. In addition, a comparison between the most commonly found ML algorithms in terms of certain SON metrics is performed and general guidelines on when to choose each ML algorithm for each SON function are proposed. Lastly, this work also provides future research directions and new paradigms that the use of more robust and intelligent algorithms, together with data gathered by operators, can bring to the cellular networks domain and fully enable the concept of SON in the near future

    Athematic participles in Brazilian Portuguese: A syncretism in the making

    Get PDF
    Some Portuguese verbs have two different past participles, such as, e.g., aceitar ‘accept’, with participles aceitado and aceito ; and limpar ‘clean’, with limpado and limpo . The first one in each pair mentioned is thematic, whereas the second one is athematic. While regular thematic participles all bear stress on the theme vowel, these athematic participles all bear the primary stress on the athematic stem. As the morphosyntactic category first person singular present indicative (1spi) is realized by {-o}, it normally coincides the masculine form of this athematic participle, giving rise to a syncretism between 1spi and the participle. The aim of this paper is to track the appearance of this kind of participle and the resulting syncretism in Portuguese and the changes making it possible for new participles to be formed in this way in colloquial Brazilian Portuguese

    An Empirical Evaluation of an Evolutionary Game Theory Model of the Labor Market

    In this paper we intend to perform an empirical evaluation of the evolutionary game theory model of the labor market developed by Araujo and Souza (2010). In order to accomplish this task we focus on the Brazilian labor market by using data from the National Household Sampling Survey – PNAD/IBGE, from 1995 to 2008. We used four different methodologies: the OLS, Pseudo-panel with fixed effects, Instrumental Variables and the Heckman Selection Model. Results indicate that the main difference between the 1995-2002 and 2003-2008 period is the impact of education over wages. According to these findings, investments in education were more profitable for the 2003-2008 period. However, all wage gaps between formal and informal markets reduced considerably.formal and informal and labor market, evolutionary game theory.
