Among all those dreams, some more reachables than others, there is the ability to create machines that think by themselves. This chimera, despite of being quite different from how our ancestors ever imagined, is nowadays at the summit of its history. The massive increase of data, through digitalization, and the constant technological improvements, in this case, in the form of progress in high performance hardware production, have been the main drivers of this change. This grade project covers a specific area that is, sometimes, a part of the aforementioned creation process, known as Artificial Intelligence. This specific area is called Deep Learning. Deep learning techniques can be regarded as the algorithms that exploit data using models based on non-linear function compositions. In this respect, optimization plays a crucial role as it is the driver that transform the information in data into the model parameters. The project aims at understanding the mathematical basis of optimization, namely stochastic optimization theory and its application to deep learning.

Las personas nos entendemos al hablar mediante tonos y gestos que añaden más profundidad o sentidos a lo que decimos. El sarcasmo se basa mucho en estos extras añadidos al lenguaje, o esa es mi percepción. Muchas veces puedes saber si alguien está siendo sarcástico por lo que sabemos de él, o porque sabemos cómo se expresa cuando bromea. Pero. ¿Cómo lo haría una máquina para conocer a todo el mundo de esta misma manera? Si el Bot funciona significa que hay elementos del lenguaje que denotan el sarcasmo más que otros, y esto es muy interesante porque hay gente que no percibe el sarcasmo cuando una máquina sí podría (es algo muy recurrente en televisión y películas, ver máquinas incapaces de hacer o identificar una broma). Además de que me fascina el hecho de que las máquinas adopten comportamientos “humanos” o puedan ser más creativas que yo (me pongo de ejemplo a pesar de que no es muy difícil ser más creativo que yo). Esto nos lleva al otro punto de la motivación del presente proyecto. Utilizo este proyecto para investigar diversas herramientas, aprender formas interesantes de resolver problemas, y descubrir cuáles son las formas de proceder al procesar datos; todo ello basándose en el aprendizaje automático. El diseño de un “Bot detector de sarcasmo” es el catalizador de todas estas ideas. El objetivo del presente proyecto es la realización de un robot que sea capaz de detectar sarcasmo en tiempo real usando la plataforma de Telegram. Gran parte de las decisiones de este proyecto han sido tomadas en torno a cuanto sé de ellas y mi interés por aprender sobre ellas o ver como ayudan al proyecto.

Treballs Finals de Grau d'Enginyeria Informàtica, Facultat de Matemàtiques, Universitat de Barcelona, Any: 2019, Director: Oriol Pujol Vila, [en] In this report I detail the study carried out on the design and implementation of a type of Business Intelligence solution in the “Faculty of Mathematics and Computer Science” of the University of Barcelona. The objective is to put into practice my theoretical knowledge and present the advantages that would be obtained if a project of this type will be carried out in which the participation of the entire organization is required and with the use of technology as a base. For this particular situation, it has been considered as a Business Intelligence solution to design several dashboards as an ideal data exploitation solution with the aim of illustrating the main areas of business interest, through KPIs, comparative data, resources graphics, etc... This is to support the "decision making" in the line of providing knowledge to the users of the organization with which they can make better decisions and generate added value in all its areas, as a result of the democratization of information . It seemed the best fit to separate the work into 4 phases. In the first phase of analysis, it was found the usual dispersion of information in various sources. A lack of specific and analytical tools, meant until now analytics were only done on demand and manually, so that the need for the design of a new technological architecture was determined. Incorporated will be the following new components: Data warehouse: It gathers the data of the organization. It is an integrated data collection, which contains all the data of the operational systems. This information is neither modified nor eliminated. • Data preparation, integration and cleaning Tool: For the extraction, transformation and loading of the data of different sources into the Data warehouse. Front-End tool or visualization: Allows the creation of the corecard showing the different KPIs marked by the organization via an interactive navigation through the data for its analysis. Collaboration platform: For the publication and sharing of scorecards between users of the organization. Once the new components in the architecture were identified, the analysis was made which specific technological tools would be chosen. In the second phase all the relevant processes are detailed. The third phase is the execution of all the processes explained in the second phase. The fourth and final phase is the presentation of the final product. (Scorecard with its respective tests and its evaluation included.)

The first one is to give a general and introductory idea of what causality is, especially in problems that can be represented by directed acyclic grafs. Do-calculus and interventions are introduced as a tool to identify and quantify causal effects. Moreover, this document wants to serve as an introductory but complete study to anyone interested in this field. The second objective is to improve in a given problem: which are the causes of altitude sickness? From here we will explore how oxygen saturation affects altitude sickness. Is low oxygen saturation the cause of altitude sickness or is it only a mediator of altitude?

In this project we study the problem of predicting the elapsed time for sport activities taking into consideration the data gathered from the user’s profile and their activities and elapsed times. More concretely, in this project we address the following topics: a protocol for gathering the data of the different activities from Strava users is proposed, data cleaning and curation is considered, and finally, the usage of different supervised learning techniques for predicting the elapsed time duration of an activity are compared and appropriate metrics are established. The project approaches the study of some machine learning methods, such as Elastic Net, Huber Regressor, Regression Trees, and lastly, additional importance is given to the study of deep neural networks (deep learning). Additionally, some metrics are also set about the success of the differents results obtained based on the accepted threshold of the regression values obtained, all of this applied in a case use of the predictors used within a business model. The results obtained show that neural networks allow us to obtain, for a sparse range of activities within a dataset, successful results in a 60% of the predictions made. But the best performance we have managed to get in this first iteration of the investigation,is yielded by the ElasticNet regressor as it has the lowest percentage of error on average. The results obtained in this project also leave a door open for potentially commercialize the investigation and being able to apply it on real case scenarios.

Iron and Time is an Action-RPG videogame developed using Unreal Engine 4, a videogame engine from Epic Games, and more precisely with its Blueprint Visual Scripting technology. If you are unfamiliar with more than three words from the couple of sentences above this is a great place to be! Through the report, we will take a deep look into Unreal Engine, we will learn how to use it, what are blueprints, how do we script with them and why did we chose it to develop this game. We will also take a look at the project structure to understand not only how could it be made but also, and more important, how it is actually made. We will also explore some difficulties we came across, including a very critical one (see THE BUG) to finally reach some conclusions about the project itself and its future.

And the fact is that the great dream of the artificial intelligence is to achieve the creation of machines as intelligent as any one of us. Even still being away from succeeding, many researchers in the matter think that the best way to achieve it is from algorithms of learning, that test to imitate how the human brain works. The artificial neural networks simulate the behaviour of the biological nervous system. It treats of a system of models of artificial neurons, interconnected, arranged in a network with the purpose to collaborate to attain their common aim: the learning. In spite of the differences of structure between the biological and the artificial system, in both cases we find a massive group of simple units of process, the neurons. And it is in their connections where the intelligence of the network is placed. We plan to tackle the backpropagation algorithm both in theoretical and practical approaches so we can build an object recognition system.

Este problema implica reconocer los componentes de la escena, y su relación con el entorno. Uno de los componentes más complejos de reconocer son los seres humanos, debido al hecho de ser un organismo articulado. Por estos motivos en este trabajo se ha querido realizar un modelo articulado capaz de adaptarse a cualquier postura que pueda realizar una persona a partir de un algoritmo matemático. Para ello cuenta con la ayuda de un conjunto de imágenes que nos dan información sobre la situación de las partes del cuerpo de la persona.

To achieve the objectives of this project, it’s necessary to develop a virtual guide system that allows the visualization of pictures, video, and the reproduction of audio and text in key points of the visit. Therefore, a mobile app will be designed, with the intention of it allowing to perform all of these tasks on an open environment of an archaeological excavation using the GPS of mobile devices. To get the route where the user will be guided, it will be necessary to create a supplementary app where the routes and key points will be acquired for the visit. ArchaeoloGPS and WalkingTour are two apps that in the beginning were meant to be used on a real environment, more specifically on Pol·lèntia excavation. The project was created under the request of the Facultat d’ Història de la Universitat de Barcelona. Due to time issues from the responsible that couldn't provide enough information and instructions of the specific needs, both apps were developed generically to complete the main goals of the project.

I have often wonder how would it be possible to create so many scenarios that are similar to the real world in a way that it would seem that you are watching a film while having fun playing. This was the reason why I decided to take this project. In this project I have designed and developed big part of the models used in the game, like for instance the different animations which was possible by using Blender, a modelling program. The use of Unity3D has allowed me to develop the different actions and interactions of the characters in the game. The type of videogame that I finally chose was an isometric view RPG based on a ‘turn-based combat’ system using the rules of the popular role game D&D. This game is set in a medieval fantasy world in which the different characters with different roles, controlled at the same time, cooperate with each other to accomplish the final objective of the game. The modelling and programming development is explained in the various sections of this document.

The game engine and editor are made with an Entity Component System architecture and with the technologies WinRt, DirectX and WIC, XAML was used to do the editor's GUI. The programming language used was C++, the IDE was Visual Studio Express 2013 and the target OS is Windows 8. The Direct X Game and Direct X and XAML App templates from Visual Studio Express 2013 were used as the base for the game engine and game engine's editor, respectively. In this memory it is explained concepts like Entity Component System and how it was applied to this project. The Entity Component System is initially explained from a Object Oriented Design perspective. Then, there's a little break from ECS, and there is a section about "the ability to deal with the cache of the computer of an OOD system". At the end, during the explanation of the implementation of the ECS, these two themes are brought together. Also, there are a few components of the engine that are explained more deeply. These components are the Graphic Engine and the Physic Engine. The Graphic Engine follows a simple approach that consist on using a Camera, and drawing everything that is inside that Camera. The Physic Engine follows a "not so traditional" approach. Basically, it updates every game object in the Y axis and then the collisions are managed, then it does the same but in the X axis. Also, the design done to create the ECS is explained. Which Components where made, how the Processors handle them and the Assemblages to generate more Entities. To create a game there are two steps. Firstly create it with the game engine's editor. Secondly, save it with the editor, the result will be a .txt file. Thirdly and finally, add that file to the game engine project, change the program to use that file and play the game engine.

The internal application is called EPM-GO SEAT where users can manage projects and create economic plannings to display and control the projects costs in the next years. This project has been made in four steps, the first one was analyze the objectives of the project to determinate what I had to implement or modify in the application. The second step was to designee the new interfaces, the interaction of the users with these interfaces and the modifications of the database if necessary. Before go to next step it’s important to show to the users the new interfaces and interactions to be sure they’ll be comfortable with and it satisfies all their need. The third step is the implementations of the new interfaces and the modifications of the application defined in the design phase. In the last phase of the project the new functionalities had to be presented to the new users and create a user manual to help future users of the application to understand how it works. Finally a migration plan was created to update the productive application where all users will be able to use the new interfaces and modifications implemented previously in the development application. This plan of migration had four important documents, first of all, a document with the steps to follow to complete the migration properly, the script SQL that modify the database of productive server, a zip with all of the new or modify code files to add to the productive server and finally a document with the test to realize after the migration process to verify that all works properly.

Treballs Finals de Grau d'Enginyeria Informàtica, Facultat de Matemàtiques, Universitat de Barcelona, Any: 2013, Director: Oriol Pujol Vila, In this paper we intend to obtain the depth mapping of a scene using a single image and a single viewpoint. Estimating the depth of a scene is a useful tool with applications in several problems inside the world of 3D modeling and computer vision, e.g. simulate the effect of semi-transparent elements, such as fog or smoke or recreate blur effect at chosen areas of a scene. Especially for this last reason, obtaining depth maps of different types of scenes becomes even more important. Currently, Microsoft Kinect [7] depth camera is one of the most reilable methods to obtain depth maps. This device, however, has several limitations, which considerably reduce its scope. Our approach aims to provide an analytical alternative for situations in which the depth camera does not work (outdoors, pressence of daylight, and so on). We want to know how far we can estimate the depth of a scene, using a single image and the viusual features we manage to extract from analyzing it. We use classifiers in order to find useful correlations between the visual features and the depth information provided by Kinect. This classification training helps us finding the most relevant features for estimate a depth map.Thus, we answer both main questions behind this paper: which is the maximum performance of analyzing visual features and which of thes features provide the best results.

In film making it refers to recording actions of human actors, and using that information to animate digital character models in 3D animation. Unfortunately, most motion capture systems on today's market are prohibitively expensive for educational institutions and small businesses. My goal is to develop a relatively low-cost competitive motion capture system. So in this research I’m looking for the answer how can create an optical mocap player with a single camera. Current motion capture methods use passive markers that are attached to different body parts of the subject and are therefore intrusive in nature. In applications such as pathological human movement analysis, these markers may introduce an unknown artifact in the motion, and are, in general, cumbersome. So the other key challenge is to produce a system that allows marker-less real-time tracking or near the real time. My ultimate objective is to build a visual system that can integrate the above mentioned components, wherewith can display the user’s movement into an avatar in the virtual space. Finally, I will propose a validation system to validate the user movements. I will evaluate the different postures or complete movements. Moreover, I want to go future and show the result in different ways, such as different viewing angles, different meshes or mesh with illumination.

Moreover, 3D imaging has been also introduced on medical diagnosis in the last years. However, volumetric objects have a rough interaction because the devices used to control them are bi-dimensional. For that reason, wearable sensors will give a three-dimensional control for this visualization helping the user to interact in a more natural manner. This kind of control has been a common subject in computer vision research, even more with the introduction of Microsoft R Kinect TM , but in the wearable sensor area, this is not a commonly extended subject of research and there are even less works including sensor fusion. This project proposes a system for managing a volume visualizer including in the development the whole system from the sensor data acquisition to the model visualization. The system will consist on two wearable sensors (with accelerometer and gyroscope) that will be attached to the arms of the user, an android phone will stream the values acquired from the sensors (via Bluetooth R communication) to the Server using a wireless TCP/IP protocol. The server will store the values in the computer and a 3D Engine will process this data using a complementary filter to fuse the acceleration (given by the accelerometer) and the angular velocity (given by the gyroscope) in order to obtain the performed action and apply the required transformations to the displayed model. In order to validate the system, a real-case example will be used, trying to find some anomalies on a 3D textured model of a heart in a simulated medical diagnose process. This project tries to build a complete system of natural interaction between the human and the computer by using wearable sensors.

In this project, we focused on Android platform, which is Open Source and uses the Java programming language. This project introduces the concepts of capturing, processing and image recognition. The aim of the plan is to make an able software to automatically recognise an image, or part of it, and show the closest image to it by comparing the original in a local database of the terminal. In order to make this possible, the project has been divided in two big points. The first one, was performed using the MATLAB, mathematical software tool. From an image stored on the user’s image gallery, and through a program created with the tool MATLAB, the five more similar images to the original one, were extracted from a database local computer hard drive. This process was done by the edge detection algorithm "Canny" and the "Bwdist", both of them calculate the distance of every pixel in the image to the nearest white pixel. At a later time we will be back to explain these algorithms and how the program runs. The second point of the project was to perform an Android app with the same goal as the first point. The difference is in the database, in this case, lies in the mobile SD card, so the image provided by the user may come from the phone's picture gallery or the camera of the terminal. This app uses calculations performed in Matlab and stored in a txt file, which in turn is stored in the phone's SD memory. This application may be a starting point for future extensions of the app, such as: become a client-server application; be able to expand the comparison data base by uploading photos in real time; allow internet connection; GPS location of the source image; etc.

Among other things, the interest of the project is to understand the development stages of a game and all that this implies for increasing my knowledge on these and its operation, as has always interested me and I would like to work in the future. As I do not have the resources of time and staff, I will work with an agile development standard known as scrum methodology which is based on sprints with fixed time periods in which they prioritize a number of tasks and you get a beta version stable and terminated. In this way we will not know the level of development reached at the end of work but it will be finished. The aim of this work is to develop a demo that can be played fluently, where you control a knight and we will beat that is known in the game as an area boss (a dragon) which is stronger than regular enemies. To do this work I used a game engine called unity which provides a number of tools to facilitate development.

Gradually my interest in the creation of these ones was increasing while playing I wondered how anyone could create such works of art. Be possible to enter a virtual world made by computer with many similarities to the real world fascinated me so much that I decided to investigate the development of video games and their creation. Finally I decided to create a third person action game for computer. It's the kind of game with which I am most familiar. A game in which a warrior girl has to be handled in order to defeat the final boss of the level by the combination of physical attacks. In this project I will focus on the design and full development of various objects in the game doing all the modeling and animation tasks necessary for the development of these. I also will implement all programming needed to interact with all the objects created previously. In this document you will find all the necessary information about the development process of this game both graphic design objects and the programming of these objects.

This change encourages new ways of develop software. This raises Equdia, an application with a new way of representing mathematical formulas oriented touch devices. This hierarchical representation is intuitive, based on the primitive logic of triangle as the fundamental unit. The application is designed to directly manipulate primitives to observe the impact of these changes in the other variables. It focuses both teaching calculus, so as to everyday, so as professional activities. Its usability has been tested and it has been well received, especially in the young groups, accustomed to use phones and tablets, because this software requires a learning time for its use.
