    Fundamentals of Data Analytics

    • Foundation
    • 3 Days
    • ClassroomClassroom

    This three-day course introduces the data analytics techniques to extract knowledge from raw data. The course aims to educate class audience on how to create data-driven models through the data mining pipeline that consists of data exploration, data preprocessing, machine learning modeling, and model evaluation. The course combines theoretical knowledge with hands-on training of the data analytics techniques. After taking this course, the participants should be able to build and evaluate data-driven models via the machine learning approach.


    This is a practical course with 50% of the time dedicated to hands-on sessions using the Data Science Profile in Schlumberger's DELFI Cognitive E&P environment and / or Orange Open Source Data Mining Software suite which is based on visual programming. Hands-on session will be based on oil and gas related datasets.
    Day 1

    Exploratory Data Analysis and Data Preprocessing

    • Introduction to Data Analytics
    • Exploratory Data Analysis (EDA) (Visualization, and Descriptive Statistics)
    • Hands-on EDA
    • Data Preprocessing (including PCA)
    • Hands-on Data Preprocessing

    Objective: On the first day of the course, the participants will be able to get a bird-eye view of the data analytics process. They will explore two of the four data analytics modules called exploratory data analysis, a necessary step to get the feel of the data, and data preprocessing, a necessary step to clean and format the data before building machine learning models. Learning will be reinforced via hands-on training using the DELFI Data Science Profile and / or Orange.

    Day 2

    Supervised Machine Learning

    • Decision Tree
    • Hands-on Decision Tree
    • Regression (Linear and Logistics)
    • Hands-on Regression
    • Model Evaluation

    Objective: On the second day of the course, the participants will be able to build data-driven models via supervised machine learning algorithms. Two representative machine learning algorithms - one for classification and the other for regression - will be covered. Model evaluation matrices (e.g., confusion matrix, ROC, AUC, etc.) and model evaluation methods (e.g., 10-fold cross validation) will be discussed towards the end of the day.

    Day 3

    Ensemble Methods and Unsupervised Machine Learning

      • Hands-on Model Evaluation
      • Ensemble Methods (Bagging, Boosting and Random Forest)
      • Hands-on Ensemble Methods
      • Cluster Analysis (k-Means and Hierarchical)
      • Hands-on Cluster Analysis
      • Class feedback and wrap up

      Objective: On the third day of the course, the participants will be introduced to more advanced machine learning techniques of ensemble methods and unsupervised machine learning algorithms. Learning will be reinforced via hands-on training using the DELFI Data Science Profile and / or Orange.

      Geoscientists, Engineers, IT professionals and aspiring Citizen Data Scientists working in the oil and gas industry who want to get introduced to data analytics techniques for building data-driven models.

      No prior experience of data analysis is required, although basic math and statistics knowledge is useful.
