Introduction to natural language understanding and chatbots
(Universitat Politècnica de Catalunya, 2018-09)
Treball Final de Grau
Accés obertThe aim of this thesis is to give an introduction to Natural Language Understanding. Many tools and language models are described along this work in order to teach a machine the ability to analyze and understand human ... -

Median bilinear models in presence of extreme values
(Institut d'Estadística de Catalunya, 2021-12-02)
Article
Accés obertBilinear regression models involving a nonlinear interaction term are applied in many fields (e.g., Goodman’s RC model, Lee-Carter mortality model or CAPM financial model). In many of these contexts data often exhibit ... -
On doubling and volume: chains
(\Institute of Mathematics, Polish Academy of Sciences\, 2018-10-01)
Article
Accés obertThe well-known Freiman–Ruzsa theorem provides a structural description of a set A of integers with |2A|=c|A| as a subset of a d–dimensional arithmetic progression P with |P|=c'|A|, where d and c' depend only on c. The ... -
On Motzkin’s problem in the circle group
(2021-09-01)
Article
Accés obertGiven a subset D of the interval (0,1), if a Borel set A¿[0,1) contains no pair of elements whose difference modulo 1 is in D, then how large can the Lebesgue measure of A be? This is the analogue in the circle group of a ... -
Optimal non-perfect uniform secret sharing schemes
(Springer, 2014)
Text en actes de congrés
Accés obertA secret sharing scheme is non-perfect if some subsets of participants that cannot recover the secret value have partial information about it. The information ratio of a secret sharing scheme is the ratio between the maximum ... -
Product of primes in arithmetic progressions
(2020-05-01)
Article
Accés obertWe prove that, for all q=2 and for all invertible residue classes a modulo q, there exists a natural number n=(650q)9 that is congruent to a modulo q and that is the product of exactly three primes, all of which are below ... -

Projecte Final de Màster Oficial
Accés restringit per decisió de l'autorThe main goal of this master thesis is to compute the sample size of the OPTIMAL study (OPTimizing Irradiation through Molecular Assessment of Lymph node), which is a non-inferiority clinical trial with survival data and ... -
SEIRD COVID-19 formal characterization and model comparison validation
(Multidisciplinary Digital Publishing Institute, 2020-07-27)
Article
Accés obertBased on a SEIRD model (Susceptible, Exposed, Infective, Recovered and Deceased) for COVID-19 infection with a new parametrization using a high infection rate, and a low fatality, we define the model in System Dynamics, ... -
The rado multiplicity problem in vector spaces over finite fields
(Muni press, 2023)
Comunicació de congrés
Accés obertWe study an analogue of the Ramsey multiplicity problem for additive structures, establishing the minimum number of monochromatic $3$-APs in $3$-colorings of $\mathbb{F}_3^n$ and obtaining the first non-trivial lower bound ... -

Towards 3n - 4 in groups of prime order
(2023-06-16)
Article
Accés obertWe show that if A is a subset of a group of prime order p such that |2.Al < 2.7652|Al and 10 < |A| < 1.25 - 10-®p, then A is contained in an arithmetic progression with at most 2A - [Al + 1 terms, and 2.4 contains an ... -

Text en actes de congrés
Accés restringit per política de l'editorialEnvironmental simulation is complex, not only due to the inherent complexity of the phenomenon that we are facing but also to the fact that the personnel involved in this kind of projects belongs to different areas and ... -
