Speech Title: Economic growth and population dynamics: a discrete time analysis
Abstract: This paper reformulates and generalizes the classical Uzawa-Lucas model of economic growth and human capital accumulation by representing time as a discrete variable and using a population law with non-constant growth rate. In addition, the model is developed by using a more general utility function than the original. In this setup, the model can be represented by a four-dimensional dynamical system, which admits a unique optimal trajectory in human and physical capital and consumption. It is shown that there is a unique non-trivial equilibrium. The results of the study are compared with the original model in discrete time. Keywords. Uzawa-Lucas model; economic dynamics; human capital; economic growth; discrete time.
Bio: Juan Gabriel Brida started his appointment in Uruguay at the UdelaR in 2014 as Full Professor in Economic Dynamics. Prior of returning to Uruguay, he was Assistant and Associate Professor in Mathematics and Economics at the School of Economics and Management of the Free University of Bolzano (2004 - 2014). Previous to moving to Italy, he was assistant professor at the Universidad de la República (Uruguay) -1987 - 2000. Dr. Brida received his Ph.D. in Economics from the University of Siena, and his degrees in Mathematics and Mathematical Education from Universidad de la República and Instituto de Profesores “Artigas” (Uruguay) respectively.

Title: Extension Prototypical Network for Few-shot Learning
Abstract: In this paper, we proposed a novel method based on extension distance for unsupervised meta-learning learning. Compared with previous algorithms, the network can also learn new classes and correctly classify them, and each class only requires a few shots for training. Among them, extension distance emerged as a new distance measurement method, which has obvious advantages over the previous Euclidean distance. This paper compares it with the prototypical network based on Euclidean distance and compares and analyzes the experimental results, the experiment that works best is the Miniimagenet dataset which improves accuracy by about 2.36%. The meta-learning method based on metric space is further explored, and experiments are carried out on three data sets and achieved good experimental results on MNIST, miniimagenet, and omniglot data sets.

Speech Title: Supporting online hotel booking: sentiment analysis of customer review and fuzzy cloud multi-criteria model
Abstract: With the vigorous development of e-commerce, consumers increasingly rely on online shopping. Online reviews have accordingly become essential support for consumers to make purchase decisions. However, the fierce competition of various e-commerce platforms and the excessive number of product reviews make purchasing decisions a challenging task for consumers; in particular, the differences in multiplatform reviews have caused confusion for consumers. This paper proposes a novel online hotel booking decision support algorithm can effectively reflect support, opposition, neutrality and hesitation sentiments and consumers’ behavioral characteristics. Online reviews are mined and analyzed using BiLSTM-attention first, and the corresponding attribute features and sentiment values of hotels are calculated. Considering the confidence level of sentiment values, the cloud model and T-spherical fuzzy set are integrated to define a novel T-spherical cloud (T-SC) concept. Then, due to the interactive impact of reviews from different platforms on consumer purchases, the operational interaction rules between T-SCs and a multilayer interaction Choquet integral operator under the T-SC environment are developed. In addition, multiple interactive information matrices with T-SC characteristics are established and converted into a comprehensive information matrix through the proposed operator. Finally, the validity of the proposed method is verified through an online hotel booking example with four hotels as the candidates set in Shanghai. The results show that seven attributes in the hotel reviews are clustered as the evaluation criteria, and the prediction accuracy of the seven attributes based on the proposed method is over 80%, or even above 90%, except for the “Facility”, which is 76.61%; Under the setting of attribute weight preference, the hotel reservation decision results can be obtained in line with the personalized needs of consumers. By comparative analysis, we also found that our method can handle online product decision problems under extreme or unusual review scenarios, and can automatically perform fine-grained sentiment analysis.

Speech Title: Significance of Double stratified magnetohydrodynamic Marangoni Casson nanofluid: An application of Probable error
Abstract: The purpose of this study is to examine the impact of double stratification in the Marangoni convective flow of the Casson nanofluid model towards a surface. Because of the permeable surface, concentration and temperature gradients have driven Marangoni convective flow. The investigation is gathered using Brownian diffusion, Thermophoretic attribute, and double stratification in Marangoni convection Casson nanofluid. Heat and mass transfer are investigated using various physical flow parameters. Using some appropriate classical transformations, the nonlinear structure of the governing partial differential equations (PDEs) is transformed into nonlinear ordinary differential equations (ODEs). The Runge Kutta fourth-order algorithm is used to solve a modified set of ODEs using a numerical method. The purpose of the illustrative graphics is to show how certain flow parameters affect the profiles of velocity, temperature, and concentration. Nusselt numbers are arranged in tabular form to study the variance in heat transmission and its relevance in industrial zones. Results show that the velocity field experiences a rise as a result of the Marangoni ratio parameter. A decrease in fluid flow is the effect of inclined MHD. Additionally, some values of the correlation coefficient, r, are less than P.E.(r), demonstrating the correlation coefficient's statistical insignificance. It should be noticed that some correlation coefficients are outstanding and that there is a strong relationship between the parameters and the physical characteristics.
