Free and open-source, and one of the most flexible and powerful data manipulation and modelling tools around, Python has become one of the most popular programming languages to learn. Rooted as it is in increasingly cutting-edge applications within artificial intelligence, Python modules and libraries are now the “go-to” building blocks for both Machine and Deep Learning. This course equips participants with the tools and a best practice methodology for data wrangling, preparing and cleaning data sets though input, pre-processing, integration and manipulation, data transformation and reduction.

This course is suitable for aspiring Data Science professionals looking to extend their existing capabilities into real business problems with machine learning applications across multiple vertical industries including Financial Services, Manufacturing, Healthcare, Pharma and Biotech, Retail, Travel & Hospitality and Energy & Utilities.

Basic knowledge of programming with Python is essential. Additional programming experience will also be helpful but not mandatory.

At the on successful completion of this course, you will be able to:
• Extract meaning from large data sets using a wide variety of machine learning, data mining, and data science techniques with the Python programming language.
• Filter, slice, iterate and evaluate datasets with Python
• Best practices in cleaning and preparing your data prior to analysis
• Use statistical techniques to transform data into a ready-to-model format
• Partitioning Data for Modelling and Modelling Techniques

•Interactive training classes in 2 days (daytime timetable) or 4 evenings (evening timetable)
•Hands-on practice after the classes with a work-based assignment in 14-21 days
•Access to support by our mentors during the course period
•Pairview Certification for achieving this competency

Learning Goal: In this module, we look at key data structures for data import and explore a wide range of techniques to connect to source and bring into a python integrated development environment (IDE).
• The Numpy Array and Pandas Dataset
• File Input/Output
o Opening a Text File
o CSV and excel
o JSON formats
• Reading and writing from the data source
…and more.

Learning Goal: This module teaches participants data preparation techniques including key steps for
handling missing data and outliers. Statistical techniques are employed in training to provide a
preliminary validation of feature characteristics.
• Handle missing values
o Deleting observations: if you have plenty!
o Imputing mean, median mode or the result of a statistical model
• Detecting outliers
• Normalization / Standardization
…and more.

Learning Goal: In this module, you will learn about sophisticated Python data handling and analysis
using Pandas and NumPy
• concatenating
• Iterating through a Sequence
• Functions for All Sequences
…and more.

Learning Goal: We take a deeper look at data transformation steps and equip participants with the
data analysis tools required to normalize and scale data and perform feature engineering.
• Normalisation
o Reducing the impact of extreme values/outliers
o Log transformations
• Scaling attributes
o specified ranges
o using mean and standard
• Attribute construction: Calculate a new variable
…and more.

Learning Goal: This module prepares trainees for machine learning by looking at what is often the
last step before setting up a test harness and training a model – feature reduction or recursive feature
• Reducing the number of attributes
o Removing irrelevant attributes: attribute selection
• Principle component analysis:
o searching for a lower-dimensional space that can best represent numeric data.
• Reducing attribute values
…and more.
