Don’t Spend A Fortune To Extract Huge Value From Your Data
Data Transformation can help unlock this value while avoiding the high costs of developing artificial intelligence. By focusing on critical steps in data transformation you can enable powerful data science and machine learning capabilities that will address many business objectives.
You can’t walk before you crawl, and you can’t run before you walk. Even if you plan to eventually develop a robust Artificial Intelligence program, the first step on this journey is data transformation of your legacy data. You will be surprised at how much value you can extract along the way.
What is Data Transformation?
Data transformation is the process of transforming your data into a usable format, optimized for your specific business goals. Whether you plan to use data science or machine learning algorithms, the type of data transformation needed will vary. By following these steps, you can transform your data for any type of analysis or modeling you wish to perform.
Steps in Data Transformation
Whether you are planning to use simple statistical modeling or machine learning algorithms, the first step is transforming your existing data into formats that are easily ingested by either type of model. The steps in data transformation are detailed in Fig. 2 below.
Proper data fusion, quality assessment, data selection, and data cleansing will enable powerful business insights, even without machine learning algorithms.
Some of your models may rely upon statistical modeling techniques that do not require feature engineering. However, should you choose to develop and/or deploy machine learning algorithms, expert feature engineering will make them sing!
Feature Engineering – the “Secret Sauce” of Data Transformation
High-performing machine learning algorithms are not possible without proper data preparation and expert feature engineering. Feature Engineering is the “Secret Sauce” that turns average machine learning (ML) algorithms into High-Performance ML Algorithms.
Feature Engineering is typically a collaboration between two parties:
- Domain experts who have a deep understanding of the data itself, and
- Machine learning engineers who are experts at choosing and optimizing machine learning algorithms.
These two roles are equally important for the success of any machine learning initiative.
What is Feature Engineering?
Feature Engineering uses domain knowledge of the data to extract the most useful features used by algorithms. These are then fed into machine learning algorithms to supercharge performance. Feature engineering consists of the creation, transformation, extraction, and selection of features from raw data.
Feature engineering uses various data optimization techniques to enhance algorithm performance.
For example, feature engineering might remove irrelevant features, and prioritize the features that are most useful to the models. The amount of data can also be reduced to a more manageable amount through feature extraction techniques. All of these are necessary elements of a high-performance machine learning initiative.
Feature Engineering, Data Transformation and Model Selection
As seen in Fig. 3, features and models work together to produce high-performing machine learning results. Selecting the right algorithms is only half the battle. In high-performing machine learning programs, model selection and feature engineering complement each other. Bad feature and/or model selection combinations can negatively affect machine learning performance. And you can’t have proper feature engineering without data transformation. It’s all tied together.
Data Transformation Unlocks Affordable Alternatives to A.I.
For companies without huge AI budgets, there are alternatives. Knowing the differences and limitations of Machine Learning and Data Science is key to choosing the right strategy.
Despite tremendous upside and hype, the dirty little secret is that full-blown Artificial Intelligence programs can be extremely costly. Also, they can take years to develop. A.I. requires layers of deep learning algorithms to build the necessary neural networks. This takes a lot of money, time, and effort. Artificial Intelligence Consulting often fails to take this into consideration.
For the purposes of this article, we will focus primarily on Data Science and Machine Learning strategies. We will avoid the more costly deep learning solutions required for A.I. The importance of Data Transformation, as well as Feature Engineering, will be highlighted.
Data Science vs Machine Learning
What is the difference between data science and machine learning and why should you care?
As you kickstart your machine learning program, why not take advantage of the significant benefits of advanced analytic techniques that do not require machine learning algorithms? After all, it will take some time to optimize your machine learning algorithms anyway. A proper data transformation initiative will prepare your data for whichever type of analysis you want to perform.
What is Data Science?
Data Science uses statistical approaches and advanced analytics techniques to extract useful insights from data. Usually in response to specific requirements from business executives, Data Science uses data analytics, mathematics, and statistics to extract those specific insights.
Data Science techniques form the core of business intelligence systems that rely partly on humans to spot trends in spreadsheets, charts or graphs.
Not very sexy, but don’t discount their value. Even today, companies rely on such methods to drive significant business value, often without machine learning. Data science case studies can be found to address many important business objectives.
For some of your business objectives, a data science-based business intelligence system may be all you need. To aid in decision making, Data Analytics Consulting may be helpful to visualize and present the data to stakeholders in your organization.
What is Machine Learning and When Should You Invest in it?
Simply put, Machine Learning is when machines can identify patterns in legacy data and then use those patterns to generate insights or predictions whenever new data is introduced into the machine learning system.
To decide when to start investing in machine learning, it is helpful to understand the limitations of data science-based Business Intelligence Systems.
As companies store data in larger quantities, and from more sources, with varying quality levels, data science-based Business Intelligence Systems fail. This is because of the “4 Vs” associated with Big Data: Volume, Variety, Velocity, and Veracity of data. At some point, relying upon humans to deal with the 4 Vs becomes untenable. That’s where introducing Machine Learning begins to make sense. Machines are simply better at handling “Big Data”.
Why Machine Learning?
Machines are far better at dealing with large data sets with disparate sources and varying quality levels.
A plethora of machine learning algorithms have been developed to handle classification, regression, and clustering tasks for these data sets. Also, not all business objectives can be accomplished with data science techniques alone. In particular, Unsupervised Learning and Reinforcement Learning algorithms enable powerful insights not possible with standard data science approaches.
