Comparing Neural and Attractiveness-based Visual Features for Artwork Recommendation

Advances in image processing and computer vision in the latest years have brought about the use of visual features in artwork recommendation. Recent works have shown that visual features obtained from pre-trained deep neural networks (DNNs) perform very well for recommending digital art. Other recent works have shown that explicit visual features (EVF) based on attractiveness can perform well in preference prediction tasks, but no previous work has compared DNN features versus specific attractiveness-based visual features (e.g. brightness, texture) in terms of recommendation performance. In this work, we study and compare the performance of DNN and EVF features for the purpose of physical artwork recommendation using transactional data from UGallery, an online store of physical paintings. In addition, we perform an exploratory analysis to understand if DNN embedded features have some relation with certain EVF. Our results show that DNN features outperform EVF, that certain EVF features are more suited for physical artwork recommendation and, finally, we show evidence that certain neurons in the DNN might be partially encoding visual features such as brightness, providing an opportunity for explaining recommendations based on visual neural models.Comment: DLRS 2017 workshop, co-located at RecSys 201

El principio de oportunidad en el nuevo sistema penal acusatorio

El Principio de Oportunidad en el nuevo sistema penal colombiano, se erige como la única excepción a la obligación que tiene la Fiscalía General de la Nación de adelantar el ejercicio de la acción penal y realizar la investigación de los hechos que revistan las características de un delito. Su nacimiento, además de estar aparejado con un sistema penal acusatorio, tiene diferentes clases de fundamentos, de entre los cuales se puede destacar la problemática del alto índice de delincuencia y la incapacidad del órgano investigativo y de la Rama Judicial en general, para investigar y juzgar la totalidad de conductas señaladas como posibles infracciones al derecho penal.Abstract: The principle of opportunity in the new penal system is the only exception to the obligation that the General District Attorney of the Nation’s office has of advancing punitive action and carrying out the investigation of the facts that probe the characteristics of a crime. Its birth, in addition to having been prepared by a penal accu- satory system, also has different classes of foundations, among which it is possible to emphasize the problem of the high rate of delinquency and the incapacity of the investigative sector and of the Judicial Branch in general, to investigate and judge the totality of conducts indicated as possible infractions to penal law

Plan de negocios de una recicladora de la limalla de acero de los procesos de mecanizado en frio

119 páginasEl emprendimiento se traduce como la búsqueda permanente de nuevas alternativas. Estas nuevas alternativas pueden ser dentro de un proceso ya implementado, la creación de un nuevo proceso, la creación de una nueva empresa, etc. Estos elementos anteriores tienen como base la creación o modificación que nacen de la creatividad y la capacidad de leer las señales del exterior. Después de un análisis realizado durante una de las asignaturas del pregrado, se vio la posibilidad de realizar aprovechar un desecho, la limalla del acero. Este desecho es inutilizado debido a su forma. La limalla del acero presenta dificultades para el manejo; es un producto bastante afilado y con unas dimensiones bastantes grandes, lo que hace que su volumen sea grande, pero su peso una vez puesto dentro de un contenedor sea mínimo.PregradoIngeniero(a) Industria

Key drivers in the behavior of potential consumers of remanufactured products: a study on laptops in Spain

[EN] Many companies have begun to implement end-of-use strategies (remanufacturing, recycling, and reuse) in response to worldwide concern about environmental issues. Simultaneously, academic research on remanufacturing has turned to focus on the analysis of activities from a supply perspective, i.e., collection of end-of-use products, reverse logistics, disassembly, assembly, etc. Very little attention has been paid, however, to the demand side of remanufactured products, in particular, to the consumer profile of these products or to determining their most effective marketing strategies. Companies interested and involved in fostering the demand for remanufactured products need to be aware of the importance of knowledge of their potential consumers in order to most suitably manage their remanufacturing and marketing activities. Given this context, the principal objective of the present work was to make a first approach to determining basics characteristics of the profile of potential consumers of remanufactured products. To this end, an empirical analysis was conducted of the key variables underlying the purchase intentions of potential consumers in order to gain insight into the key drivers of that behavior. The instrument used was a questionnaire elaborated for application to potential consumers of a specific product (laptops) in two Spanish universities. The results revealed the drivers that explain the self-declared purchase intention of a remanufactured laptop, and provide managers of firms interested in implementing green initiatives in their supply chain with useful information for their consideration of closed-loop supply chains and for integrating marketing decisions concerning remanufactured products into the development of end-of-use strategies.SIBeatriz Jiménez-Parra and Sergio Rubio thank the Government of Extremadura and FEDER for the funding they received through Research Project PRI09A09

An approximation to the Remanufactured Electrical and Electronic Equipment Consumer

Remanufacturing of electrical and electronic products can be considered as an excellent business opportunity from an economic point of view. The success factor in these remanufacturing activities is the recovery process of the economic value of the end-of-use products in order to achieve energy savings, lower manufacturing costs and less dependency on raw materials. This way, our research aims to study the demand of Remanufactured Electrical and Electronic Equipment (REEE). In particular, the consumer profile of this kind of products is analyzed in this paper, in order to describe what variables can determine his/her purchasing intention. This is a work in progress so the results of this paper provide a very first approach to the profile of the REEE consumer by using a descriptive analysis of the main variables, which can become an important support for future research
