    Advances in Processing, Mining, and Learning Complex Data: From Foundations to Real-World Applications

    Get PDF
    Processing, mining, and learning complex data refer to an advanced study area of data mining and knowledge discovery concerning the development and analysis of approaches for discovering patterns and learning models from data with a complex structure (e.g., multirelational data, XML data, text data, image data, time series, sequences, graphs, streaming data, and trees) [1–5]. These kinds of data are commonly encountered in many social, economic, scientific, and engineering applications. Complex data pose new challenges for current research in data mining and knowledge discovery as they require new methods for processing, mining, and learning them. Traditional data analysis methods often require the data to be represented as vectors [6]. However, many data objects in real-world applications, such as chemical compounds in biopharmacy, brain regions in brain health data, users in business networks, and time-series information in medical data, contain rich structure information (e.g., relationships between data and temporal structures). Such a simple feature-vector representation inherently loses the structure information of the objects. In reality, objects may have complicated characteristics, depending on how the objects are assessed and characterized. Meanwhile, the data may come from heterogeneous domains [7], such as traditional tabular-based data, sequential patterns, graphs, time-series information, and semistructured data. Novel data analytics methods are desired to discover meaningful knowledge in advanced applications from data objects with complex characteristics. This special issue contributes to the fundamental research in processing, mining, and learning complex data, focusing on the analysis of complex data sources

    Mestrado em Engenharia de Viticultura e Enologia (Double Degree) / Instituto Superior de Agronomia. Universidade de Lisboa / Faculdade de Ciências. Universidade do PortoBunch compactness (BC) is a key target for wine sector because it affects disease susceptibility, berry ripening among other grapes characteristics. The most common method to estimate BC is the O.I.V. descriptor n°204: manual and subjective. Objective and automated methods are based on indices, using different relations between bunch traits, some obtained manually and other automatically through image analysis (as example: BW – weight; BV – volume; ML – maximum length; A – projected area; MVO – morphological volume; V3 – derived volume; BN – berries number). All the variables were significantly and positively correlated between each other: the highest Pearson correlation coefficient was between BW and BV (r = 0.99) followed by BW and A (r = 0.95). Fourteen compactness indices (CI) were tested (9 published and 5 created) on 61 Syrah bunches. These indices were then correlated with the mode of the O.I.V. descriptor n°204, where 11 were positively correlated and three were negatively correlated (CI-3, CI-3a, CSF). The index CI-10a, which relates bunch weight and maximum length, was the most suitable one to define BC (r = 0.78). In the frame of the EU VINBOT project, to improve BW estimation finding the best explanatory variables, a stepwise regression analysis between BW and the variables considered easy to extract by automated image analysis (A1 – projected area, V3 – volume 3, BN – berries number and CI-10a as index) was performed. The variable which explained best BW was A1 (partial R2 = 0.905), followed by CI-10a and V3 with a much smaller contribution (partial R2 <0.06 and partial R2<0.007, respectively). The variable BN was not selected by the model. We concluded that BC can be estimated in an objective and automatic way using image analysis. Furthermore, such estimations can enhance BW prediction by using BC as one of the explanatory variables which can improve automatic yield estimation methodologiesN/

    The main objective of this research was to find out the possibility to use digital images of forewings in the species identification of codling moth. The suitability of different areas of forewing as identification marks was also determined. Digital RGB images were used to determine the features of forewings of three different Cydia species (Lepidoptera, Tortricidea). The chosen species were Cydia pomonella, Cydia splendana and Cydia strobilella. Text-based descriptions of the visual appearances of the moth species were used in feature selection. Image processing methods were applied on 6 different areas of 12 different forewings. 168 local features were calculated for each area. Features included direct pixel-wise intensity values and spatially filtered values. Stepwise regression was performed in order to reduce the number of features in linear models. The models were tested with linear regression analysis and hierarchical agglomerative clustering. Based on this research, Cydia pomonella can be identified from the two other Cydia species by forewing images. The identification was more reliable when the features of all 6 target areas were included compared to the case that the features of only 3 target areas were included. However, the forewings of Cydia pomonella were separated correctly from the forewings of two other Cydia species with 3 visible areas. Identification of sitting Cydia pomonella can be based on the measured or calculated features in the white-brown veined area in the middle of the forewing and in the bronze coloured oval in the sub marginal area but possibly not in the dark brown stripe in the inner margin of the forewing. To have distinctive features in regression models, it is recommended to use 21 x 21 –sized or 9 x 9 -sized filtered values rather than direct pixel-wise measurements.Tutkimuksessa haluttiin selvittää, voidaanko omenakääriäinen erottaa muista lähilajeista etusiivestä otetun digitaalikuvan avulla. Lisäksi haluttiin selvittää ne etusiiven alueet, joista lajitunnistus kannattaisi tehdä. Tutkimuksessa käytettiin digitaalisia RGB-kuvia kolmen Cydia-lajin lajitunnistukseen. Tutkimukseen valittiin kohdelajiksi omenan tuholainen, Cydia pomonella, sitä ulkonäöltään läheisesti muistuttava Cydia splendana sekä näistä kahdesta ulkonäöltään selvästi erottuva Cydia strobilella. Etusiivistä valittiin alueet, joissa tekstipohjaisen tiedon perusteella sijaitsivat tyypilliset lajituntomerkit. Tutkimukseen otetuista 12 etusiivestä määritettiin 6 aluetta, joista kaikista määritettiin 168 piirrettä. Piirteisiin kuului muun muassa paikallisia pikselikohtaisia intensiteettejä sekä suodatettuja mittaustuloksia. Piirteiden määrän vähentämiseksi käytettiin askeltavan regressioanalyysin algoritmeja. Valittujen piirteiden perusteella muodostettiin lineaarisia malleja, jotka testattiin lineaarisella regressioanalyysillä ja hierarkisella kokoavalla ryvästyksellä. Tutkimuksen perusteella Cydia pomonella –laji pystytään erottamaan kahdesta muusta Cydia-suvun lajista etusiivistä otettujen digitaalikuvien perusteella. Kaikkien kolmen Cydia –suvun lajin lajitunnistus oli luotettava, kun kuvien 6 tutkittua aluetta otettiin mukaan analyyseihin. Cydia pomonellan etusiivet pystyttiin erottamaan kahdesta muusta Cydia –suvun lajin etusiivistä myös vain kolmen alueen perusteella. Lajitunnistus kannattaa tehdä siiven keskiosan juovikkaan alueen sekä siiven päädyssä olevan pronssinvärisen ovaalin alueen perusteella, mutta luultavasti ei siiven keskiosan tummanruskean viirun perusteella. Erottelevimmat piirteet saatiin 21 x 21 ja 9 x 9 –kokoisilla suotimilla suodatetuista alueista, jotka selittivät paremmin lajien välistä eroa kuin pikselikohtaiset intensiteetit

    Three-dimensional quantitative characterization of grapes morphology and possible relation with grey mould susceptibility

    Get PDF
    Grey mould is one of the most important diseases of grapevine in the Mediterranean regions caused by the fungi Botrytis cinerea. Many factors are responsible for this disease among them, the morphology of grapes plays a crucial role in grey mould infection. The grapes with highly compact berries are the most susceptible to infection. The common methods applied to evaluate the compactness of grapes cannot apply to grapevine bunches from the same variety. Therefore, novel methods are used to detect compactness by image processing analyses such as photogrammetry for 3D model reconstruction. This study proposes an alternative analysis of bunch morphology and compaction assessment based on virtual 3D models. Seventeen Pinot Gris clones and six Pinot Noir clones were manually collected at harvest time, and the grey mould severity evaluation was carried out in the field. All the grapes were photographed at different angulations, and the 3D model reconstruction was performed by the photogrammetry technique. Several measures and indexes were extracted from each bunch. Principal component analysis (PCA) and two multiple linear regression models (MLR) were applied to identify the descriptors of the clones most related to grey mould infection. The first model assessed the correlation between the grey mould severity and the descriptors from the 2D analysis, while the second model analyzed both descriptors from the 2D and 3D analysis. The 3D MLR presented higher performances than the 2D MLR. The R-square value (R2) and the root mean square error (RMSE) were compared between models. For Pinot Gris, the R2 rose from 0.656 to 0.838, moving from the 2D to the 3D MLR, while the RMSE decreased from 1.713 to 1.175. In Pinot Noir, the 2D model did not provide sufficient robustness, while the proposed MLR estimated R2 with 0.936 value and RMSE with 0.29 value. Additional studies were performed by analyzing the data with graphs and statistics. Consequently, the most significant traits include the estimated empty volume, the width of the grape, weight, volume, shape, and the ratio between surface and height.Grey mould is one of the most important diseases of grapevine in the Mediterranean regions caused by the fungi Botrytis cinerea.

    A Hybrid k-Means Cuckoo Search Algorithm Applied to the Counterfort Retaining Walls Problem

    Full text link
    [EN] The counterfort retaining wall is one of the most frequent structures used in civil engineering. In this structure, optimization of cost and CO2 emissions are important. The first is relevant in the competitiveness and efficiency of the company, the second in environmental impact. From the point of view of computational complexity, the problem is challenging due to the large number of possible combinations in the solution space. In this article, a k-means cuckoo search hybrid algorithm is proposed where the cuckoo search metaheuristic is used as an optimization mechanism in continuous spaces and the unsupervised k-means learning technique to discretize the solutions. A random operator is designed to determine the contribution of the k-means operator in the optimization process. The best values, the averages, and the interquartile ranges of the obtained distributions are compared. The hybrid algorithm was later compared to a version of harmony search that also solved the problem. The results show that the k-mean operator contributes significantly to the quality of the solutions and that our algorithm is highly competitive, surpassing the results obtained by harmony search.The first author was supported by the Grant CONICYT/FONDECYT/INICIACION/11180056, the other two authors were supported by the Spanish Ministry of Economy and Competitiveness, along with FEDER funding (Project: BIA2017-85098-R).García, J.; Yepes, V.; Martí Albiñana, JV.
