Data analyzing and Machine Learning Hands-on with KNIME

Hands-on crash course guiding through codeless, user-friendly, free data science software KNIME Analytics Platform

Ratings: 4.61 / 5.00




Description

The goal of this course is to gain knowledge how to use open source Knime Analytics Platform for data analysis and machine learning predictive models on real data sets.

The course has two main sections:

1. PRE-PROCESSING DATA: TRANSOFRMING AND VISUALIZING DATA FRAMES

In this part we will cover the operations how to model, transform and prepare data frames and visualize them, mainly:

  • table transformation (merging data, table information, transpose, group by, pivoting etc.)

  • row operations (eg. filter)

  • column operations (filtering, spiting, adding, date information,  missing values, adding binners, change data types, do basic math operations etc.)

  • data visualization (column chart, line plot, pie chart, scatter plot, box plot)


2.  MACHINE LEARNING - REGRESSION AND CLASSIFICATION: We will create machine learning models in  standard machine learning process way, which consists in:

  1. data collection with reading nodes into the KNIME software (the data frames are available in this course for download)

  2. pre-processing and transforming data to get well prepared data frame for the prediction

  3. visualizing data with KNIME visual nodes (we will create basic plots and charts to have clear picture about our data)

  4. understanding what machine learning is and why it is important

  5. creating machine learning predictive models and evaluating them:

  • Simple and Multiple linear Regression

  • Polynomial Regression

  • Decision Tree Classification

  • Decision Tree Regression

  • Random Forest Regression

  • Random Forest Classification

  • Naive Bayes

  • SVM

  • Gradient booster

I will also explain the Knime Analytics Platform environment, guide you through the installation , and show you where to find help and hints.

One lecture is focused on working with Metanodes and Components.
