Using association rules to assess purchase probability in online stores
2016
The paper addresses the problem of e-customer behavior characterization based on Web server log data. We describe user sessions with the number of session features and aim to identify the features indicating a high probability of making a purchase for two customer groups: traditional customers and innovative customers. We discuss our approach aimed at assessing a purchase probability in a user session depending on categories of viewed products and session features. We apply association rule mining to real online bookstore data. The results show differences in factors indicating a high purchase probability in session for both customer types. The discovered association rules allow us to formu…
Identifying legitimate Web users and bots with different traffic profiles — an Information Bottleneck approach
2020
Abstract Recent studies reported that about half of Web users nowadays are intelligent agents (Web bots). Many bots are impersonators operating at a very high sophistication level, trying to emulate navigational behaviors of legitimate users (humans). Moreover, bot technology continues to evolve which makes bot detection even harder. To deal with this problem, many advanced methods for differentiating bots from humans have been proposed, a large part of which relies on supervised machine learning techniques. In this paper, we propose a novel approach to identify various profiles of bots and humans which combines feature selection and unsupervised learning of HTTP-level traffic patterns to d…
Impact of information and in-home sensory exposure on liking and willingness to pay: The beginning of Fairtrade labeled coffee in France.
2015
This study was conducted to assess how the Fairtrade label interacts with the perception of intrinsic product characteristics on liking and purchase decisions and to estimate the evolution of this interaction after exposure to the coffees and/or exposure to ethical information. In a first session, 119 consumers gave liking scores for 2 regular and 2 Fairtrade coffees under a blind tasting condition. Then, they were asked to indicate the maximum price they would pay for each product in 2 auctions taking place under different information conditions. In the first auction, participants saw the packaging but did not taste the coffee; in the second auction, they could both taste the coffee and se…

<title>Multifeature image and video content-based storage and retrieval</title>
1996
In this paper we present most recent evolution of JACOB, a system we developed for image and video content-based storage and retrieval. The system is based on two separate archives: a 'features DB' and a 'raw-data DB'. When a user puts a query, a search is done in the 'features DB'; the selected items are taken form the 'raw-data DB' and shown to the user. Two kinds of sessions are allowed: 'database population' and 'database querying'. During a 'database population' session the user inserts new data into the archive. The input data can consist of digital images or videos. Videos are split into shots and for each shot one or more representative frames are automatically extracted. Shots and …
Análisis de las habilidades del manejo del grupo en un programa de educación afectivo-sexual para DFI
2021
Las habilidades de manejo de grupo que presenten los profesionales que imparten los programas de educación afectivo-sexual para personas con discapacidad intelectual son esenciales a fin de dirigir las sesiones hacia los objetivos establecidos. Por ello, el objetivo del presente trabajo es explorar las incidencias producidas durante la aplicación del Programa SALUDIVERSEX, en función del tipo de contenido de la sesión, analizando las habilidades de manejo del grupo de los 29 profesionales (90% mujeres y 10% hombres) que aplicaron este programa. Los resultados sugieren que las conductas inapropiadas de los/as usuarios/as son las incidencias más frecuentes tanto en las sesiones que trabajan h…
What happens after five years?: The long-term effects of a four-session Acceptance and Commitment Therapy delivered by student therapists for depress…
2017
Brief interventions can be viable treatment options worth consideration in addressing the growing need for treatments of subclinical and clinical depressive symptoms. However, there is uncertainty regarding the long-term benefits of these interventions. The aim was to examine the long-term (5-year) effects of a 4-session Acceptance and Commitment Therapy (ACT) intervention for low mood delivered by novice therapists in order to see whether lasting effects could be achieved cost-effectively with four intervention sessions. Originally, 57 self-referred clients were randomized into two groups: an intervention group and a waiting-list control group which received treatment later. The groups wer…
Resultados preliminares de la eficacia del programa saludiversex de educación afectivo-sexual para adultos con diversidad funcional intelectual
2021
Para promover un desarrollo sexual saludable es necesario garantizar el acceso de las personas con discapacidad intelectual (PDI) a la formación en relación con sexualidad y las relaciones interpersonales. En este sentido, se precisan programas de educación afectivo sexual para PDI que presenten evidencias empíricas sólidas acerca de su validez. Con este objetivo, el presente estudio ofrece los datos preliminares sobre la eficacia de cuatro de las sesiones del Programa de Educación Afectivo-Sexual SALUDIVERSEX: (1) Higiene íntima, (2) Abuso sexual, (3) Orientación sexual e (4) Intimidad. El programa fue aplicado a 43 usuarios de cuatro centros ocupacionales de la Comunitat Valenciana. La im…
Use of a Virtual Environment to Engage Motor and Postural Abilities in Elderly Subjects With and Without Mild Cognitive Impairment (MAAMI Project)
2016
Objectives: In the context of rehabilitation, the use of new technology such as Virtual Reality Technology (VRT) offers multiple possibilities to modulate the functional stimulation of subjects according to needs. Material and methods: In this study, the validity and reliability of our VRT system were investigated in fifteen healthy aged adults (HAA) and seven aged subjects with mild cognitive impairment (MCI). One implicit session was designed through two virtual environments (VEs) in order to induce the adapted activities associated with balance and postural control. In comparison, the same activities were achieved in explicit sessions with a physiotherapist. This cross-over study made us…
Innovative Educational Pathways in Spine Surgery: Advanced Virtual Reality–Based Training
2020
Background Over the past few years, a reorganization of the educational pathways has been promoted with the purpose of optimizing the acquisition of competences and their assessment, so as to reduce the risks to both health care professionals and end users. Virtual reality (VR) has been repeatedly tested, initially as a positive reinforcement for more traditional educational pathways and, more recently, as their potential substitute. The aim of this study was to demonstrate the potentiality of VR simulation training in spine surgery. Methods The VR simulator reproduced the lateral lumbar access to the spine. The simulation included a tutorial, the preoperative settings, and the surgical ses…
