Once the data has been prepared and is in a good format - we can then move on to labeling the data for input in machine learning algorithms. ![]() The transforming of data can also be known as the preparing of data and includes cleaning and error detection. Once the data has been moved and stored in the correct place, the next step would be to explore the data and transform it where required. This is where ETL comes into the picture, with other steps such as infrastructure, pipelines, structure, and unstructured data storage. The next step would be to move and store that data. Once you collect the data if it is through an external source, user-generated content, sensors, etc. Let’s go through the steps on how ETL is important to machine learning. This training data needs to be of good quality and hold features and characteristics that can help to solve the task at hand.ĮTL during the process of producing effective machine learning algorithms is found at the base - the foundation. In order for a machine learning algorithm to be trusted and perform well it needs large amounts of training data. If you don’t prepare your data through ETL - there’s no difference between it staying in the raw format in data warehouses or just sitting in the cloud. The aim of ETL is to prepare your data so that it is in the best-suited format to be used in machine learning. Businesses have been able to scale and continue to be innovative since Cloud Computing entered the market.īut your data still needs to be stored in a central repository, regardless if it's through traditional data warehouses or the cloud. That’s where Cloud Computing has benefited us all.Ĭloud Computing has not only allowed us to store large volumes of data but also helped us perform high-speed analytics. Yes, we generate and collect a lot of data with it growing at such an exponential rate that we can physically store all of it in a traditional data warehouse infrastructure. These stages make the workflow of machine learning algorithms smooth and produce accurate outputs that we can trust. Accuracy - all the points above improve the overall accuracy of the data and its outputs which can be imperative to comply with regulations and standards.Productivity - it eliminated heavy coding processes, saving both time and money and improves productivity.Interpretable - with more data, we have a consolidated view and can make better interpretations through analysis and reports.Context - organizations have more historical data to provide them with context.When you combine different datasets in a centralized repository, it provides: So why just leave it there to do nothing? We all know what data can do in this day and age - the things it’s been able to create, the problems it has solved, and how it can benefit our future. Meaning that they are in different formats, inconsistent, and do not communicate with other aspects of the business well. Most companies have a lot of data but they tend to be siloed. The benefits it brings to machine learning are that it helps extract data, clean it up and deliver it from Point A to Point B. Once your data is in the correct format, it can be loaded into the target database.Įvery part of the ETL phase is important to deliver the end product accurately. During the TRANSFORM stage, you will clean up the data, search and rectify any duplicates and prepare it to be loaded into another database. Like the majority of the time when working with data and machine learning algorithms - there’s a phase of cleaning it up. This can be located in another database or application overall. ![]() Your first step will be to EXTRACT the data from its original source. It is the process of moving data from multiple sources to bring it to a centralized single database. It is the machine learning algorithms that produce these predicted outputs by learning on historical data and its features.ĮTL stands for Extract-Transform-Load. So what does ETL have to do with machine learning?įor those who don’t already know, machine learning is a type of artificial intelligence that uses data analysis to predict accurate outcomes. You may have heard ETL getting thrown in sentences here and there when you're reading blogs or watching YouTube videos.
