\nDue date: 21 March 2022
\nThe given excel sheet is based on Eltom et al. (2016) paper. The sheet lists the lab measurement of 156 samples collected from two locations near Riyadh, Saudi Arabia. A total of 87 measurement and relations are given for each sample.
\nThe target of this study is to predict the depositional environments, referring to Eltom et al. (2016) \u201cthe interpretation of depositional environments provides important information to understand facies distribution and geometry. The classical approach to interpret depositional environments principally relies on the analysis of lithofacies, biofacies and stratigraphic data, among others. An alternative method, based on geochemical data (chemical element data), is advantageous because it can simply, reproducibly and efficiently interpret and refine the interpretation of the depositional environment of carbonate strata. Here we geochemically analyze and statistically model carbonate samples (n=156) from seven sections of the Arab-D reservoir outcrop analog of central Saudi Arabia, to determine whether the elemental signatures (major, trace and rare earth elements [REEs]) can be effectively used to predict depositional environments.\u201d
\nIn this homework, we shall apply an unsupervised technique (K-mean and\/or DBSCAN) to cluster the given data into different groups, each group (cluster) represents a lithofacies associated with a different depositional environment.
\nNote that:
\n\u2022 Set 62 is the rare earth element (REE)
\n\u2022 Set 63 is the light rare earth element (LREE)
\n\u2022 Set 64 is the medium rare earth element (MREE)
\n\u2022 Set 65 is the heavy rare earth element (HREE)
\nQuestions and Requirements
\n1. Study the given data before you start the process to select which features should be excluded from the process
\n2. Select a number of features for the clustering process
\n3. Apply K-mean to cluster the given data
\n4. Use an Assessment approach to identify the optimum number of clusters (elbow is an example, but you can use other approaches such as (va = evalclusters(data,idx,’CalinskiHarabasz’);) in MatLab.
\n5. Apply DBSCAN on the same data set using the same features (Matlab code is provided)
\n6. Compare the K-mean and the DBSCAN results
\n7. Comment on the results
\nExpected Deliverables
\nA short report contains at least the following
\n1. A list of the excluded features. Give reason(s) for the exclusion
\n2. A table and\/or a figure shows the K-mean result
\n3. Describe your final clusters and explain the main characteristics of each cluster
\n4. The result of the elbow test (Figure and explanation)
\n5. A table and\/or a figure shows the DBSCAN result
\n6. What are the similarities and differences between K-mean and the DBSCAN results
\n7. Short conclusions
\nExpectations
\n\u2022 Text should be free from typos, spelling errors, and grammar errors
\n\u2022 Figure should be in a good shape and good resolution.
\n\u2022 Figures should have axis scale, labels, titles, and Figure captions.
\n\u2022 Report should be divided at least into \u201cSummary\u201d, \u201cTesting and selecting features\u201d, \u201cK-mean result\u201d, \u201cDBSCAN results\u201d, \u201cK-mean vs. DBSCAN\u201d, and \u201cConclusions\u201d.
