How to get data ready for machine learning?

The process for getting data ready for a machine learning algorithm can be summarized in three steps: Step 1: Select Data. Step 2: Preprocess Data. Step 3: Transform Data. You can follow this process in a linear manner, but it is very likely to be iterative with many loops.

How to preprocess data?

Three common data preprocessing steps are formatting, cleaning and sampling: 1 Formatting: The data you have selected may not be in a format that is suitable for you to work with. The data may be in a relational database and you would like it in a flat file, or the data may be in a proprietary file format and you would like it in a relational database or a text file. 2 Cleaning: Cleaning data is the removal or fixing of missing data. There may be data instances that are incomplete and do not carry the data you believe you need to address the problem. These instances may need to be removed. Additionally, there may be sensitive information in some of the attributes and these attributes may need to be anonymized or removed from the data entirely. 3 Sampling: There may be far more selected data available than you need to work with. More data can result in much longer running times for algorithms and larger computational and memory requirements. You can take a smaller representative sample of the selected data that may be much faster for exploring and prototyping solutions before considering the whole dataset.

What is the final step in a process?

The final step is to transform the process data. The specific algorithm you are working with and the knowledge of the problem domain will influence this step and you will very likely have to revisit different transformations of your preprocessed data as you work on your problem.

Why is training important in machine learning?

It results in the model learning from the data so that it can accomplish the task set. Over time, with training, the model gets better at predicting.

What is machine learning model?

A machine learning model determines the output you get after running a machine learning algorithm on the collected data. It is important to choose a model which is relevant to the task at hand. Over the years, scientists and engineers developed various models suited for different tasks like speech recognition, image recognition, prediction, etc. Apart from this, you also have to see if your model is suited for numerical or categorical data and choose accordingly.

What are the benefits of machine learning?

Understanding data

Before walking, one has to learn to crawl. So before understanding how data can be prepared we need to ask ourselves: What is data?

Types of Data

There are two main categories of data we need to consider, each has two subsets. The primary categories of data do not overlap, they are:

Qualitative data

This is data that is acquired through observation and cannot be quantified using numbers of variables. For example the taste of ice cream and ketchup. If you take 10 volunteers and ask them to review the taste, they will say something like: disgusting, vile, or delicious.

Methods of data collection

After understanding data you now have to find a way to collect it. Understand that there is no wrong or right way to collect data. How you collect data is dependent upon the resources you have. So do not worry if you are not using real-time telemetry to receive data from sensors or any other fancy stuff.

Understanding Machine Learning

The phrase machine learning gets thrown about a lot. It is extremely popular but poorly understood. To put it simply: machine learning is a procedure we perform to teach or allow Artificial intelligence to learn. Like a student attending classes, so they can learn to become a better artist.

Step by step guide to preparing data for machine learning

Now we are going to dive into the technicalities of organizing our data so that you can deploy it with ease.

How Bad Data influences Decision-Making

In our daily lives, we are constantly making tiny decisions, what to eat, what to wear, etc. Whether we realize it or not, all these decisions are based on data.
