چکیده

Le Chatbots sono applicazioni che simulano il dialogo intelligente con esseri umani. Il paradigma di realizzazione più utilizzato è l’approccio Stimolo-Risposta (S/R). Lo Stimolo è un insieme di frasi attese dalla chatbot, la Risposta sono le frasi restituite all’utente. Spesso tale approccio limita le potenzialità dell’interazione: la chatbot risponde solo quando la frase sottomessa dall’utente corrisponde ad una delle frasi attese. L’obiettivo del lavoro è il “rilassamento” di S/R attraverso due approcci: la semantica relazionale (relazione semantica tra parole) e la semantica distribuzionale (correlazione statistica tra parole). Attraverso tali meccanismi, la chatbot può rispondere anche in presenza di forte similarità tra la frase di input ed una frase attesa, mantenendo ancora coerenti le risposte. L’adozione di questi approcci permette, quindi, di migliorare le prestazioni base della chatbot.

Gains from diversification on convex combinations: A majorization and stochastic dominance approach

By incorporating both majorization theory and stochastic dominance theory, this paper presents a general theory and a unifying framework for determining the diversification preferences of risk-averse investors and conditions under which they would unanimously judge a particular asset to be superior. In particular, we develop a theory for comparing the preferences of different convex combination...

Improved immunogenicity of tetanus toxoid by Brucella abortus S19 LPS adjuvant.

BACKGROUND Adjuvants are used to increase the immunogenicity of new generation vaccines, especially those based on recombinant proteins. Despite immunostimulatory properties, the use of bacterial lipopolysaccharide (LPS) as an adjuvant has been hampered due to its toxicity and pyrogenicity. Brucella abortus LPS is less toxic and has no pyrogenic properties compared to LPS from other gram negati...

Steady electrodiffusion in hydrogel-colloid composites: macroscale properties from microscale electrokinetics.

A rigorous microscale electrokinetic model for hydrogel-colloid composites is adopted to compute macroscale profiles of electrolyte concentration, electrostatic potential, and hydrostatic pressure across membranes that separate electrolytes with different concentrations. The membranes are uncharged polymeric hydrogels in which charged spherical colloidal particles are immobilized and randomly d...

Perturbative Analysis of Dynamical Localisation

In this paper we extend previous results on convergent perturbative solutions of the Schrödinger equation of a class of periodically timedependent two-level systems. The situation treated here is particularly suited for the investigation of two-level systems exhibiting the phenomenon of (approximate) dynamical localisation. We also present a convergent perturbative expansion for the secular fre...

Collinear contextual suppression

The context of a target can modulate behavioral as well as neural responses to that target. For example, target processing can be suppressed by iso-oriented surrounds whereas it can be facilitated by collinear contextual elements. Here, we present experiments in which collinear elements exert strong suppression whereas iso-oriented contextual surrounds yield no contextual modulation--contrary t...
