Rosén, Fredrik. "Correlation based clustering of the Stockholm Stock Exchange." Thesis, Stockholm University, School of Business, 2006. http://urn.kb.se/resolve?urn=urn:nbn:se:su:diva-6500.
Full textThis thesis present a topological classification of stocks traded on the Stockholm Stock Exchange based solely on the co-movements between individual stocks. The working hypothesis is that an ultrametric space is an appropriate space for linking stocks together. The hierarchical structure is obtained from the matrix of correlation coefficient computed between all pairs of stocks included in the OMXS~30 portfolio by considering the daily logarithmic return. The dynamics of the system is investigated by studying the distribution and time dependence of the correlation coefficients. Average linkage clustering is proposed as an alternative to the conventional single linkage clustering. The empirical investigation show that the Minimum-Spanning Tree (the graphical representation of the clustering procedure) describe the reciprocal arrangement of the stocks included in the investigated portfolio in a way that also makes sense from an economical point of view. Average linkage clustering results in five main clusters, consisting of Machinery, Bank, Telecom, Paper & Forest and Security companies. Most groups are homogeneous with respect to their sector and also often with respect to their sub-industry, as specified by the GICS classification standard. E.g. the Bank cluster consists of the Commercial Bank companies FöreningsSparbanken, SEB, Handelsbanken and Nordea. However, there are also examples where companies form cluster without belonging to the same sector. One example of this is the Security cluster, consisting of ASSA (Building Products) and Securitas (Diversified Commercial \& Professional Services). Even if they belong to different industries, both are active in the security area. ASSA is a manufacturer and supplier of locking solutions and SECU focus on guarding solutions, security systems and cash handling. The empirical results show that it is possible to obtain a meaningful taxonomy based solely on the co-movements between individual stocks and the fundamental ultrametric assumption, without any presumptions of the companies business activity. The obtained clusters indicate that common economical factors can affect certain groups of stocks, irrespective of their GICS industry classification. The outcome of the investigation is of fundamental importance for e.g. asset classification and portfolio optimization, where the co-movement between assets is of vital importance.

Full textMålet med detta projekt att undersöka eventuella samband mellan marknadsföringsemail och dess mottagare med hjälp av oövervakad maskininlärning på en brgränsad mängd data. Datan består av ca 1200 email meddelanden med 98.000 mottagare. Initialt så gruperas alla meddelanden baserat på innehåll via text klustering. Meddelandena innehåller ingen information angående tidigare gruppering eller kategorisering vilket skapar ett behov för ett oövervakat tillvägagångssätt för inlärning där enbart det råa textbaserade meddelandet används som indata. Projektet undersöker moderna tekniker så som bag-of-words för att avgöra termers relevans och the gap statistic för att finna ett optimalt antal kluster. Datan vektoriseras med hjälp av term frequency - inverse document frequency för att avgöra relevansen av termer relativt dokumentet samt alla dokument kombinerat. Ett fundamentalt problem som uppstår via detta tillvägagångssätt är hög dimensionalitet, vilket reduceras med latent semantic analysis tillsammans med singular value decomposition. Då alla kluster har erhållits så analyseras de mest förekommande termerna i vardera kluster och jämförs. Eftersom en initial kategorisering av meddelandena saknas så krävs ett alternativt tillvägagångssätt för evaluering av klustrens validitet. För att göra detta så hämtas och analyseras alla mottagare för vardera kluster som öppnat något av dess meddelanden. Mottagarna har olika attribut angående deras syfte med att använda produkten samt personlig information. När de har hämtats och undersökts kan slutsatser dras kring hurvida samband kan hittas. Det finns ett klart samband mellan vardera kluster och dess mottagare, men till viss utsträckning. Mottagarna från samma kluster visade likartade attribut som var urskiljbara gentemot mottagare från andra kluster. Därav kan det sägas att de resulterande klustren samt dess mottagare är specifika nog att urskilja sig från varandra men för generella för att kunna handera mer detaljerad information. Med mer data kan detta bli ett användbart verktyg för att bestämma mottagare av specifika emailutskick för att på sikt kunna öka öppningsfrekvensen och därmed nå ut till mer relevanta mottagare baserat på tidigare resultat.

Full textClustering algorithms have focused on the management of numerical and categorical data. However, in the last years, textual information has grown in importance. Proper processing of this kind of information within data mining methods requires an interpretation of their meaning at a semantic level. In this work, a clustering method aimed to interpret, in an integrated manner, numerical, categorical and textual data is presented. Textual data will be interpreted by means of semantic similarity measures. These measures calculate the alikeness between words by exploiting one or several knowledge sources. In this work we also propose two new ways of compute semantic similarity based on 1) the exploitation of the taxonomical knowledge available on one or several ontologies and 2) the estimation of the information distribution of terms in the Web. Results show that a proper interpretation of textual data at a semantic level improves clustering results and eases the interpretability of the classifications

Full textA pele humana é constituída de uma série de camadas distintas, cada uma das quais reflete uma porção de luz incidente, depois de absorver uma certa quantidade dela pelos pigmentos que se encontram na camada. Os principais pigmentos responsáveis pela origem da cor da pele são a melanina e a hemoglobina. A segmentação de pele desempenha um papel importante em uma ampla gama de aplicações em processamento de imagens e visão computacional. Em suma, existem três abordagens principais para segmentação de pele: baseadas em regras, aprendizado de máquina e híbridos. Elas diferem em termos de precisão e eficiência computacional. Geralmente, as abordagens com aprendizado de máquina e as híbridas superam os métodos baseados em regras, mas exigem um conjunto de dados de treinamento grande e representativo e, por vezes, também um tempo de classificação custoso, que pode ser um fator decisivo para aplicações em tempo real. Neste trabalho, propomos uma melhoria, em três versões distintas, de um novo método de segmentação de pele baseado em regras que funciona no espaço de cores YCbCr. Nossa motivação baseia-se nas hipóteses de que: (1) a regra original pode ser complementada e, (2) pixels de pele humana não aparecem isolados, ou seja, as operações de vizinhança são levadas em consideração. O método é uma combinação de algumas regras de correlação baseadas nessas hipóteses. Essas regras avaliam as combinações de valores de crominância Cb, Cr para identificar os pixels de pele, dependendo da forma e tamanho dos agrupamentos de cores de pele gerados dinamicamente. O método é muito eficiente em termos de esforço computacional, bem como robusto em imagens muito complexas.
