Improving Dialogue Management: Quality Datasets vs Models

Task-oriented dialogue systems (TODS) have become crucial for users to interact with machines and computers using natural language. One of its key components is the dialogue manager, which guides the conversation towards a good goal for the user by providing the best possible response. Previous works have proposed rule-based systems (RBS), reinforcement learning (RL), and supervised learning (SL) as solutions for the correct dialogue management; in other words, select the best response given input by the user. However, this work argues that the leading cause of DMs not achieving maximum performance resides in the quality of the datasets rather than the models employed thus far; this means that dataset errors, like mislabeling, originate a large percentage of failures in dialogue management. We studied the main errors in the most widely used datasets, Multiwoz 2.1 and SGD, to demonstrate this hypothesis. To do this, we have designed a synthetic dialogue generator to fully control the amount and type of errors introduced in the dataset. Using this generator, we demonstrated that errors in the datasets contribute proportionally to the performance of the model

Comparison of Different Classifiers and the Majority Voting Rule for the Detection of Plum Fruits in Garden Conditions

Color segmentation is one of the most thoroughly studied problems in agricultural applications of remote image capture systems, since it is the key step in several different tasks, such as crop harvesting, site specific spraying, and targeted disease control under natural light. This paper studies and compares five methods to segment plum fruit images under ambient conditions at 12 different light intensities, and an ensemble method combining them. In these methods, several color features in different color spaces are first extracted for each pixel, and then the most effective features are selected using a hybrid approach of artificial neural networks and the cultural algorithm (ANN-CA). The features selected among the 38 defined channels were the b* channel of L*a*b*, and the color purity index, C*, from L*C*h. Next, fruit/background segmentation is performed using five classifiers: artificial neural network-imperialist competitive algorithm (ANN-ICA); hybrid artificial neural network-harmony search (ANN-HS); support vector machines (SVM); k nearest neighbors (kNN); and linear discriminant analysis (LDA). In the ensemble method, the final class for each pixel is determined using the majority voting method. The experiments showed that the correct classification rate for the majority voting method excluding LDA was 98.59%, outperforming the results of the constituent methods.This research was funded by the Spanish MICINN, as well as European Commission FEDER funds, under grant RTI2018-098156-B-C53.

Análisis del juego de ataque en balonmano femenino

.- This study focuses on the specific organization of the attacking strategies in women's handball. In particular, we explore the specific weight of the two possible modalities of attack: positional and counterattack. To do so, during the 2008/2009 season, we have analyzed through a systematic observation methodology, direct and non-participant, the matches of a team that plays in the First Division of Women's Handball. To determine the rates of effectiveness, we have studied more than 2000 attacks and 900 throws on goal. Statistical analysis revealed that counterattack is more effective than positional play, and that it has a closer relationship with victory.Este estudio examinó la específica organización del juego de ataque en balonmano femenino. En concreto, hemos explorando el peso específico de los dos posibles tipos de ataque: posicional y contraataque.

Hemos estudiado más de 2000 jugadas de ataque y 900 lanzamientos a portería, determinando de esta manera los índices de efectividad. El análisis estadístico reveló que existe una mayor eficacia del contraataque frente al juego posicional, además de una mayor relación con la victoria final

Retrospective health impact assessment for ozone pollution in Mexico City from 1991 to 2011

AbstractAir pollution is the main environmental issue in Mexico City, where ozone is one of the most damaging pollutants for human health. In this work we present a retrospective health impact assessment (HIA) study split up by age groups for evaluating the benefits of ozone regulatory strategies from 1991 to 2011 in Mexico City. Since people move from one place to another during the day, which may affect their potential exposure to pollutants, we consider time-dependant spatial population distributions during the day. Ozone data is made up of observations taken with hourly frequency from January 1, 1991 to December 31, 2011, at approximately 22 stations of the monitoring network of Mexico City. Interpolated values for unknown locations are also taken into account in the HIA. The Cressman objective analysis method is applied for interpolating the observed ozone concentrations from monitoring stations to grids of convenient resolution. We demonstrate that different age groups present different spatial patterns of exposure, being the working-age people (between 18 and 64 years) the most benefited. We also confirm the hypothesis that, in general, people move to less polluted regions during the day

El plano secuencia en Berlanga: lenguajes y técnicas de la comedia

Luis García Berlanga discovered in the sequence shot technique an ideal instrument to narrate his stories through the continuous movement of the camera, the massive choreography of the actors and the mise en scène in terms of depth. In the Valencian filmmaker's work, long takes serve to offer a particular vision of the comedy genre, introducing a series of internal editing resources which, as well as allowing him to develop his particular sense of humour on screen, enable the author to carry out a critical analysis of human existence and of cinema itself, by opting for certain audiovisual production decisions such as the predominance of extended duration shots, wide and dynamic framing, simultaneous and overlapping dialogues, strong compositional contrasts within the image or accelerated rhythms of the dramatic action, among other aesthetic and narrative solutions. The Berlin sequence shot is thus a privileged means of stylising reality, abstracting the everyday, eternalising the present, the precise comic vehicle to make us laugh and think.Luis García Berlanga descubrió en la técnica del plano secuencia un instrumento idóneo para narrar sus historias a través del movimiento continuado de cámara, la coreografía masiva de actores y la puesta es escena en términos de profundidad. En la obra del cineasta valenciano, las tomas largas sirven para ofrecer una visión particular del género de la comedia, introduciendo una serie de recursos de montaje interno que, además de permitirle desarrollar en pantalla su particular sentido del humor, capacita al autor para llevar a cabo un análisis crítico de la existencia humana y del propio cine, al decantarse por determinadas decisiones de realización audiovisual como la predominancia de planos de duración extendida, encuadres amplios y dinámicos, diálogos simultáneos y solapados, fuertes contrastes compositivos dentro de la imagen o ritmos acelerados de la acción dramática, entre otras soluciones estéticas y narrativas. El plano secuencia berlanguiano resulta, de este modo, un medio privilegiado para estilizar la realidad, abstraer lo cotidiano, eternizar el presente, el vehículo cómico preciso para hacernos reír y reflexionar

Unraveling the Holocene Eruptive History of Flores Island (Azores) Through the Analysis of Lacustrine Sedimentary Records

Lacustrine sequences from active volcanic settings usually hold a rich and continuous record of tephra layers, providing a critical source of information to reconstruct a most complete eruptive history of a region. Lake sedimentary records on volcanic islands are particularly useful as the typical small size of these islands and their steep subaerial and submarine slopes lead to a lower preservation of potential erodible pyroclastic deposits. Here we explore the lacustrine sedimentary record of Lagoa da Lomba, a crater lake in the central upland area of Flores Island (Azores), to gain insight into the recent eruptive history of this island. The strategic location of Lagoa da Lomba, half distance between the two clusters of recent volcanic activity of the island, together with its long-lasting record, back to 23.52 cal kyr BP, makes this lake a privileged site to investigate the Holocene volcanic history of Flores. Based on a detailed stratigraphic characterization of sediments from a lake transect of three cores, supported by glass shard geochemistry and radiocarbon dating, we recognized four Holocene eruptive events taking place between 6.28 and 2.36 cal kyr BP, demonstrating that the Holocene volcanic activity at Flores Island may have lasted longer than previously reported. Glass shard geochemistry from the different tephra layers suggests three populations, basaltic to trachybasaltic in composition, where the last eruption is the least evolved endmember. Two of the four eruptive events correlate with subaerially-exposed pyroclastic sequences, in terms of stratigraphy and geochemistry. The most recent event recorded at Lagoa da Lomba was constrained to 3.66 - 2.36 cal kyr BP and linked to an eruption sourced from Lagoa Comprida Volcanic System. The second most recent eruptive event was sourced from Lagoa Funda Volcanic System and dated at 3.66 cal kyr BP. Our observations show that Flores experienced vigorous volcanic activity during the Late Holocene. Therefore, contrary to what is assumed, the possibility of future eruptions should be properly considered, and the volcanic hazard here should not be underestimated. Moreover, we highlight the importance of tephrostratigraphy in recent lake sediments to reconstruct past volcanic activity, especially at small volcanic islands, such as Flores, where exposure is poor due to erosion within the limited subaerial area and the dense vegetation

Synchronize your \textit{chrono-brane}: Testing a variable brane tension model with strong gravitational lensing

Brane world models have shown to be promising to understand the late cosmic acceleration, in particular because such acceleration can be naturally derived, mimicking the dark energy behaviour just with a five dimensional geometry. In this paper we present a strong lensing joint analysis using a compilation of early-type galaxies acting as a lenses, united with the power of the well studied strong lensing galaxy cluster Abell\,1689. We use the strong lensing constraints to investigate a brane model with variable brane tension as a function of the redshift. In our joint analysis we found a value $n = 7.8^{+0.9}_{-0.5}$, for the exponent related to the brane tension, showing that $n$ deviates from a Cosmological Constant (CC) scenario (n=6). We obtain a value for the deceleration parameter, $q(z)$ today, $q(0)=-1.2^{+0.6}_{-0.8}$, and a transition redshift, $z_t=0.60\pm0.06$ (when the Universe change from an decelerated phase to an accelerated one). These results are in contrast with previous work that favors CC scenario, nevertheless our lensing analysis is in agreement with a formerly reported conclusion suggesting that the variable brane tension model is able to source a late cosmic acceleration without an extra fluid as in the standard one.Comment: ACCEPTED TO BE PUBLISHED IN THE EUROPEAN PHYSICAL JOURNAL
