Preprocess and data analysis techniques for affymetrix DNA microarrays using bioconductor: a case study in Alzheimer disease
(2013-08-12)
DNA microarray, or DNA chip, is a technology that allows us to obtain the
expression level of many genes in a single experiment. The fact that numerical
expression values can be easily obtained gives us the possibility ...
An investigation of imputation methods for discrete databases and multi-variate time series
(2016-10-03)
When it comes to information sets in real life, often pieces of the whole set
may not be available. This problem can find its origin in various reasons, describing
therefore different patterns. In the literature, this ...
Application of advanced regression methods for wear prediction of superalloys
(2018-01-18)
Analytical models able to predict the tool wear can provide companies instruments to optimize the cutting processes. The focus of this thesis is to accomplish a study of the tool wear process in the turning process of ...
Image-based family verification in the wild
(2017-09-15)
Facial image analysis has been an important subject of study in the communities of pat-
tern recognition and computer vision. Facial images contain much information about the
person they belong to: identity, age, gender, ...
Accommodations deduplication
(2018-09-25)
The problem to address is the accommodations deduplication. The deduplication is
a special case of entity resolution (ER) consisting in grouping different representa-
tions of the same entity, usually coming from different ...
Statistical natural language generation for dialogue systems based on hierarchical models
(2014-09-25)
Due to the increasing presence of natural-language interfaces in our life, natural
language processing (NLP) is currently gaining more popularity every year.
However, until recently, the main part of the research activity ...
Dialog Systems based on Markov decision processes over two real tasks
(2013-06-12)
In this work the state of the art of the automatic dialogue strategy
management using Markov decision processes (MDP) with reinforcement
learning (RL) is described. Partially observable Markov decision processes
(POMDP) ...
Study of an object recognition algorithm
(2013-06-12)
This project introduces an improvement of the vision capacity of the robot Robotino
operating under ROS platform.
A method for recognizing object class using binary features has been developed. The
proposed method ...
Building a predictive model for Kaggle's “Home Depot Product Search Relevance” Competition
(2016-10-14)
The present work analyses different techniques in order to build a predictive model that could be able to solve the Kaggle’s competition called “Home Depot Product Search Relevance”. Several NLP methods were used for data ...
