Certified Analytics Professional Training – Description
Data Science Introduction and difference between BI and Data Science
Data science is considered as an evolutionary step in interdisciplinary fields that includes computer science, modeling, statistics, and mathematics. Data science has become an integral part of competitive intelligence in businesses these days which includes data mining and data analysis. This chapter includes a brief introduction to data science and the history of data science.
Data Science Introduction and difference between BI and Data Science continued
Technological advancements have made businesses focus more on the future by analyzing the data. To improve the business companies have started to transform data into insights which are called real data science.
Whereas on the other hand companies are also using Business Intelligence activities to use the data and create charts, reports, and graphs.
To take care of these functions companies appoint dedicated BI analysts as well as data scientists. But many companies get confused between these two concepts. This chapter gives you the difference between Business Intelligence and Data Science on certain factors.
- Area of Focus
- Data Analysis and Quality
- Data Sources and Transformation
- Need for Mitigation
A contrastive chart which represents the difference between Data Science and Business Intelligence based on three factors Content/Tools, Business, and Data are also provided under this chapter.
How Data Science Work along with Acquire and Prepare Steps
The data science workflow contains four important phases or stages. They are the Preparation Phase, Analysis Phase, Reflection Phase and the Dissemination Phase. This workflow of the data science is represented using a picture in this chapter. Under this chapter, the preparation and analysis phase is explained in detail.
Preparation phase contains two steps – Acquire data, Reformat and clean data.
The first step in data science is to acquire the data and convert it into a form that is suitable for computation. Data can be acquired from a variety of sources like websites, API, software’s, physical apparatus, etc. The problems faced in this step are provenance, data management, and storage. These problems are explained in detail under this topic.
The raw data cannot be used as such for data science. Programmers reformat and clean the data so that it is suitable for further analysis. Reformatting and cleaning the data can help to make few assumptions about the data. Data integration is the hurdle faced in this step. This is explained in detail in this chapter.
How to Analyse and Act Data
The main phase of the data science is the analysis phase. Analyze phase includes writing, executing and refining the programs to analyze the data and gather knowledge from it. These programs are known as data analysis scripts. Few scripting languages like Python, R and Perl are explained in brief under this section.
The iteration cycle of the analysis phase is explained with the help of a diagram for easy understanding. The analysis phase contains three main sources of slowdowns – Absolute running times, Incremental running times and Crashes from errors. These slowdowns are discussed in brief in this chapter.
This chapter also includes the challenges faced in the analysis stage of data science.
Reflection Phase and Dissemination phase
Reflection phase involves the communication of output about the analysis. The reflection can be in different forms like Notes, Holding meetings, Making comparisons and finding out alternatives. These reflection methods are explained in detail in this chapter. An example of the pictorial representation of the analysis is also given under this chapter for easy learning.
Dissemination phase is the final phase of Data science process. This is mostly in the form of written reports. The phase includes four stages – Write reports, Deploy online, Archive experiment and Share experiment. The major problem faced in this phase is the consolidation of the data. This chapter deals with the dissemination phase in detail.
Guiding Principles and Reasoning and Common Sense
The guiding principles of Data Science are not hard and fast rules to be strictly followed. But these guiding principles will help you in decision making. There are five guiding principles of data science explained in detail in this chapter. They are
- Be willing to fail
- Fail often and learn quickly
- Keep the goal in mind
- Dedication and focus lead to success
- Complicated does not equal better
Reason and common sense are foundations of data science. Without these two data is considered just as a collection of bits. Any context or model created by humans are not fully reliable. Blindly trusting such context will lead to wrong conclusions. Therefore you need to ask yourself few questions before carrying on with such context.
- What problem are you trying to solve?
- Does the approach make any sense?
- Does the answer make any sense?
- Is it a finding or a mistake?
- Does the analysis address the original intent?
- Is the story complete?
- Where would it lead you next?
Components of Data Science for Certified Analytics Professional Training
The components of a data science fall under different categories like
- Data types
- Execution models
- Learning models
- Analytic Classes
There is an interconnection among these components. These components are explained in detail in this chapter.
Classes of Analytic Techniques – Transforming, Learning and Predictive Certified Analytics Professional
The classes of analytic techniques are grouped into nine basic classes to help conceptualize the universe of possible analytic techniques. The nine analytic techniques are divided into three topics which are listed below
- Transforming – Aggregation, Enrichment, Processing
- Learning – Regression, Clustering, Classification, Recommendation
- Predictive – Simulation, Optimization
These techniques are explained in detail in this section.
Learning Models, Execution Models Scheduling and Sequencing
The learning models define the type of judgments and how the models change over time. The learning models are further classified into Learning style and Training Style.
- Learning style – Unsupervised, Semi-Supervised, Supervised
- Training Style – Offline, Reinforcement, Online
This tutorial contains the brief description of these learning models.
Execution model explains how data is manipulated to perform an analytic function. These execution models are further classified based on different dimensions and how they handle data. The classifications are
- Scheduling – Batch, Streaming
- Sequencing – Serial, Parallel
Each of the execution models of data science is briefed under this chapter.
Decomposing Analytical Problem
Decomposing the problem into several pieces is the first and foremost step in the analytic selection process. The concept of decomposition is explained using the Fractal Analytic Model. The Problem Decomposition Using the Fractal Analytic Model is explained using a pictorial representation. There are few things to consider when decomposing your problem
- Compound analytic goals that create natural segmentation
- Natural Orderings of Analytic goals
- Data types that dictate processing activities
- Requirements for human-in-the-loop feedback
- The need to combine multiple data sources
Data Science Maturity – Certified Analytics Professional
Calculating the maturity of a data science capability gives a different view to data science for Certified Analytics Professional within an organization. The data science maturity model describes the maturity progression and components that form data science capability. There are several stages of data science maturity model and at each stage, some knowledge is gained. There are five stages and each stage is explained by its description and example.
Feature Engineering Dimensionality Reduction and Model Validation
Feature Engineering is like a oxygen to data science. Feature engineering is the foundational skill and an challenging art in Data science. Feature engineering establishes the representation of data in the context of an analytic approach. The feature engineering concept is given in detail in this tutorial.
Machine learning gives an important result “Curse of Dimensionality”. The dimensionality reduction is needed under different situations. These situations are given under this chapter. Different types of dimensionality reduction techniques are also provided in this section.
Model validation helps in the construction of any model. This lets you know whether your hypothesis fits the observed data. There are many techniques available to combat model overfitting. One method is splitting the data into training, testing and validation sets. In this chapter, you will learn how the model is evaluated on each data set.
