Evaluating Hybrid Neural Network Approaches to Multimodal Web Page Classification Based on Textual and Visual Features / Extrahering av Representationer och Ensembletekniker för Multimodal Klassifiering av Webbsidor. : Utvärdering av neurala nätverksmodeller och ensembletekniker för multimodal webbsideklassificering.

Ivarsson, Anton January 2021 (has links)
Given the explosive growth of web pages on the Internet in the last decade, automatic classification and categorization of web pages have grown into an important task. This thesis sets out to evaluate whether or not methods for text and image analysis, which had not been evaluated for web page classification, could improve on the state-of-the-art methods in web page classification. In web page classification, there is no dataset that is used for benchmarking. Therefore, in order to make comparisons, baseline models are implemented. The methods implemented are Bidirectional Encoder Representations from Transformers (BERT) for text and EfficientNet B4 for images. This thesis also sets out to evaluate methods for combining knowledge from two models. The thesis concludes that the proposed methods do improve on the state-of-the- art methods in web page classification. The proposed methods achieve approximately 92% accuracy while the baselines achieve approximately 87%. The proposed methods and the baselines are shown to be different using McNemar’s test at a significance level 0.05. The thesis also concludes that weighted average of logits could be preferable to weighted average of probabilities; weighted average of logits could be a more robust method, although more research is needed. / Givet den explosiva tillväxten av webbsidor på Internet under det senaste decenniet har automatisk klassificering och kategorisering av webbsidor vuxit till en viktig uppgift. Denna avhandling syftar till att utvärdera huruvida nya metoder för text- och bildanalys, som inte hade utvärderats för klassificering av webbsidor, skulle kunna prestera bättre än de senaste metoderna som har använts i området. Inom webbsideklassificering finns det inget dataset som används för jämförelser. För att göra jämförelser implementeras därför referensmodeller. De nya metoderna som implementerats är Bidirectional Encoder Representations from Transformers (BERT) för text och EfficientNet B4 för bilder. Den här avhandlingen syftar också till att utvärdera metoder för att kombinera kunskap från två modeller. Avhandlingen drar slutsatsen att de nya metoderna presterar bättre än de senaste metoderna inom klassificering av webbsidor. De nya metoderna uppnår cirka 92% noggrannhet medan referensmodellerna uppnår cirka 87%. De nya metoderna och referensmodellerna visar sig vara olika med hjälp av McNemars test med en signifikansnivå av 0.05. Avhandlingen drar också slutsatsen att det viktat genomsnitt av logits skulle kunna vara att föredra framför viktat genomsnitt av sannolikheter; viktat genomsnitt av logits skulle kunna vara en mer robust metod men måste undersökas mer.

Improving Aircraft Fuel Consumption Prediction through Ensemble Learning / Förbättrande av bränsleförbrukningsestimering genom ensembleinlärning

Gongzhang, Hanlin January 2022 (has links)
Performance models provided by aircraft manufacturers are used by aircraft operators to perform flight path simulations aiming to reduce aircraft fuel consumption. However, performance models are generic and does not account for the performance deviations of each aircraft individual. The performance deviations, particularly in terms of fuel consumption, will affect the dynamic programming of flight path simulations. This may result in a less optimal flight path and ultimately lead to higher fuel consumption than expected. In hope of reducing this risk, a collection of local performance factors were derived. These factors describe the percentual deviation between the real fuel flow and the levels predicted by the performance model, and are allocated with respect to a range of flight parameters in a data library known as the performance library. A test environment is then constructed to simulate a continuous flow of flight data, where a new performance library is derived from the flight data of every month. The local performance factors of the previous month are then updated with the current; a learning process based on the weighted average ensemble approach. Further, the local performance factors are used in conjunction with the performance model to estimate the aircraft fuel consumption during cruise. The observed average prediction error is noticeably smaller than that of an equivalent global, scalar performance factor used by airlines today. The result also reveals that the prediction accuracy and versatility of the performance library is mainly determined by its resolution - higher resolution generally offers better accuracy at a cost of requiring more flight data, whereas lower resolutions are more versatile but of lower accuracy. Finally, the performance libraries of two identical aircraft are used to trace the performance deviation between them. The weighted average of all local performance factors in the performance library of respective aircraft reveal that the average fuel consumption is roughly -1.9 % and -2.5 % lower than the estimates by the performance model, ultimately proving that it is feasible to detect overall fuel efficiency deviation between two identical aircraft. / Prestandamodeller tillhandhållna av flygplanstillverkarna används oftast av flygbolagen för att utföra flygruttsimuleringar i syfte att bespara bränsle. Dock är prestandamodellerna generiska och tillgodoräknar inte prestandaavvikelserna som förekommer hos varje flygplansindivid. Dessa prestandaavvikelser, speciellt i form av bränsleförbrukning, kommer att påverka den dynamiska programmeringen i flygruttssimulationen. Följde när flygrutter som kan leda till högre förbrukningar än de ursprungligen uppskattades. I hopp om att minimera denna risk beräknades mängder av lokala prestandafaktorer, vilka grundar på prestandamodellens avvikelse från verkliga flygdata. Dessa koefficienter allokerades sedan till ett databibliotek (prestandabibliotek) med avseende på en samling av flygparametrar. En testmiljö konstruerades i följd för att simulera ett kontinuerligt dataflöde. Vidare skapades ett prestandabibliotek för varje månadsflygdata, där de nyskapade lokala prestandafaktorerna viktas med de motsvarandeparterna i föregående månadens prestandabibliotek, vilket är en inlärningsprocessbaserad på viktad medelvärdesensemble. Prestandabiblioteket applicerades sedan över prestandamodellen och det snittliga uppskattning felet observerades vara märkbart mindre än det från en motsvarande global, skalärbaserad prestandafaktor. Resultatet antyder också på att prestandabibliotekets uppskattningsnoggrannhet och allsidighet beror huvudsakligen på dess upplösning - en hög upplösning leder generellt till ökad uppskattningsnoggrannhet med på bekostnad av mer flygdata, medan lägre upplösningar tenderar att vara mer allsidiga men med mindre uppskattningsnoggrannhet. Slutligen användes prestandabiblioteken av två identiska flygplan för att spåra prestandaavvikelser som förekommer mellan dem. Viktat medelvärde av alla prestandafaktorer i respektiveflygplanets prestandabibliotek tyder på att snittförbrukningen är ungefär 1,9 % respektive2,5 % lägre än det som uppskattades av prestandamodellen. Härmed bevisades att det är möjligt att spåra varianser i snittförbrukningen mellan två identiska flygplan.

Avaliação de preços de ações: proposta de um índice baseado nos preços históricos ponderados pelo volume, por meio do uso de modelagem computacional / Stock prices assessment: proposal of a index based on volume weighted historical prices through the use of computer modeling

Colliri, Tiago Santos 03 May 2013 (has links)
A importância de se considerar os volumes na análise dos movimentos de preços de ações pode ser considerada uma prática bastante aceita na área financeira. No entanto, quando se olha para a produção científica realizada neste campo, ainda não é possível encontrar um modelo unificado que inclua os volumes e as variações de preços para fins de análise de preços de ações. Neste trabalho é apresentado um modelo computacional que pode preencher esta lacuna, propondo um novo índice para analisar o preço das ações com base em seus históricos de preços e volumes negociados. O objetivo do modelo é o de estimar as atuais proporções do volume total de papéis negociados no mercado de uma ação (free float) distribuídos de acordo com os seus respectivos preços passados de compra. Para atingir esse objetivo, foi feito uso da modelagem dinâmica financeira aplicada a dados reais da bolsa de valores de São Paulo (Bovespa) e também a dados simulados por meio de um modelo de livro de ordens (order book). O valor do índice varia de acordo com a diferença entre a atual porcentagem do total de papéis existentes no mercado que foram comprados no passado a um preço maior do que o preço atual da ação e a sua respectiva contrapartida, que seria a atual porcentagem de papéis existentes no mercado que foram comprados no passado a um preço menor do que o preço atual da ação. Apesar de o modelo poder ser considerado matematicamente bastante simples, o mesmo foi capaz de melhorar significativamente a performance financeira de agentes operando com dados do mercado real e com dados simulados, o que contribui para demonstrar a sua racionalidade e a sua aplicabilidade. Baseados nos resultados obtidos, e também na lógica bastante intuitiva que está por trás deste modelo, acredita-se que o índice aqui proposto pode ser bastante útil na tarefa de ajudar os investidores a definir intervalos ideais para compra e venda de ações no mercado financeiro. / The importance of considering the volumes to analyze stock prices movements can be considered as a well-accepted practice in the financial area. However, when we look at the scientific production in this field, we still cannot find a unified model that includes volume and price variations for stock prices assessment purposes. In this paper we present a computer model that could fulfill this gap, proposing a new index to evaluate stock prices based on their historical prices and volumes traded. The aim of the model is to estimate the current proportions of the total volume of shares available in the market from a stock distributed according with their respective prices traded in the past. In order to do so, we made use of dynamic financial modeling and applied it to real financial data from the Sao Paulo Stock Exchange (Bovespa) and also to simulated data which was generated trough an order book model. The value of our index varies based on the difference between the current proportion of shares traded in the past for a price above the current price of the stock and its respective counterpart, which would be the proportion of shares traded in the past for a price below the current price of the stock. Besides the model can be considered mathematically very simple, it was able to improve significantly the financial performance of agents operating with real market data and with simulated data, which contributes to demonstrate its rationale and its applicability. Based on the results obtained, and also on the very intuitive logic of our model, we believe that the index proposed here can be very useful to help investors on the activity of determining ideal price ranges for buying and selling stocks in the financial market.
