Machine Learning and Analytics: An Expert Guide

Michael Chen  Senior Writer  October 22, 2024

Machine learning and analytics have become indispensable tools for businesses seeking to extract valuable insights from their data. By using powerful algorithms and statistical models, organizations can uncover hidden patterns, make more data-driven decisions, and gain a competitive edge in today's rapidly evolving marketplace.

While teams can analyze data without machine learning, the results may fall short of expectations. The fact is, ML significantly boosts the capabilities of analytics platforms.

What Is Machine Learning?

Machine learning is a subset of artificial intelligence that uses algorithms trained on large data sets to recognize trends, identify patterns and relationships, and then use that information to make predictions or inform decisions without being explicitly programmed and with minimal human intervention.

Machine learning technology has applications in many industries, including healthcare, finance, marketing, and cybersecurity. Results improve through an iterative learning process that focuses on increasing accuracy, adding customization, and reducing errors in the model.

What Is Analytics?

Analytics is the process of deriving insights from data and using them to draw conclusions or make decisions. It involves collecting, cleaning, and organizing data to identify trends, correlations, and patterns. By using various statistical and mathematical techniques, analytics helps organizations make better-informed decisions, improve performance, and optimize operations.

Analytics is related to the field of statistics, which provides the underlying concepts that help companies understand their data and use it to drive growth and success. In business, the term analytics often refers to using software to sort through data, find unique relationships, and present findings in an accessible way through visualizations.

Key Takeaways

Machine Learning and Analytics Explained

Analytics efforts benefit significantly from the application of machine learning and other AI techniques. Analytics tools that don’t rely on machine learning use static algorithms that may miss obscure but important patterns in data. Machine learning can find those patterns, and, if need be, examine data sets larger and more varied than legacy analytics tools can handle.

Does Analytics Include Machine Learning?

Analytics does not necessarily require machine learning. For years, businesses used tools founded in statistical analysis to analyze trends in data, predict future outcomes, and assess the effectiveness of strategies. Without the benefit of ML, they sought to answer questions like, How well did our holiday discounting strategy work? What products or services are most popular with this customer segment? Which are the most profitable? While traditional methods could produce answers, without ML the process is limited in scope and the number of data points available.

To find answers, online analytical processing, or OLAP, has been used for decades to grab a segment of transactional data and analyze it using classical statistical analysis. When data is structured, as it is in a relational database, OLAP is highly effective. However, when data is both structured and unstructured and includes nonnumeric information about the business, statistical analysis can’t provide the same level of insight. Among other benefits, ML lets analysts identify more complex nonlinear patterns, even in unstructured sources of data.

As organizations put more unstructured data into their data warehouses, ML will be increasingly important for analyzing it all.

Why Are Machine Learning and Analytics Important for Business?

Together, machine learning and analytics extract valuable insights and predictions from a wide array of data. That can deliver a competitive edge for businesses because today, data comes from everywhere, and in some cases, all the time: Internal operational metrics, supplier and vendor inventories, marketing campaign results, data from customer apps, related data from public sources, financial data, data generated by Internet of Things devices—the modern technology ecosystem generates data from nearly every interaction and feeds it into a data warehouse or cloud-based repository such as a data lake.

That’s a lot of information, and it presents plenty of opportunities for businesses to find insights on operations, marketing, supply chain, and much more—but only if they can analyze large volumes of diverse data. Enter machine learning. With machine learning, the entire process of business analytics becomes more manageable and broader in scope for reasons including the following:

Adding to the excitement now around ML-powered analytics is the scalability and flexibility offered by cloud-based data warehouses and analytics tools. Huge amounts of data and complex machine learning algorithms demand lots of computing power for efficient analysis. And because this is a fast-evolving space, developers and data scientists looking to build and deploy new models benefit from online tools and services specifically designed for machine learning and analytics. The cloud allows organizations to use the latest data analysis innovations while providing easy access to anyone in the organization with proper credentials to use the system.

Using Machine Learning in Business Analytics

Once an organization collects inputs from various sources into a repository, machine learning systems can start processing heavy volumes of data in support of strategic initiatives. These initiatives can be part of operations, marketing, logistics, and even public engagement on social media.

Here are some popular uses for machine learning in business analytics.

Understanding Analytics

It’s always useful to review the actions you’ve taken to determine if you achieved the best possible outcome. Reflecting on past performance usually leads to improvements the next time around. Analytics should always have these sorts of goals—what can you achieve by finding actionable insights in data?

Statistical analysis of numeric data is a worthy starting point. But that potentially leaves a lot of data unanalyzed or at the very least, produces slow results while opening the door to human error. ML can help broaden analysis to find insights that aren’t easily discerned otherwise.

Types of Analytics

Companies have a wide range of analytics types and techniques to choose from, and the best fit for a project often depends on what the team wants to get out of its data. The following are four categories of analytics.

Steps in the Analytics Process

In general, the process requires collecting and cleaning data, choosing a technique, interpreting results, and communicating insights to stakeholders. Collaboration between data analysts, domain experts, and decision-makers can be helpful to ensure that insights generated are relevant and impactful.

  1. Identify the issue. All analytics should address a business issue. Are you trying to analyze marketing data? Find out what’s driving employee turnover? Discover the weak link in your supply chain? Identifying the issue creates a starting point for analytics projects.
  2. Collect and clean the data. Now that project goals are established, identify the data sources needed by the analytics platform. Options include using an iPaaS system that links data sources or connecting to a repository such as a data lake or data warehouse. To ensure compatibility and accuracy, data also needs proper formatting for processing. Cleansing usually involves removing duplicate entries and denormalizing data before analysis. For repeatable data sources, machine learning can help automate part of the cleaning and transformation process to improve efficiency.
  3. Explore and visualize data. Using analytics tools, you can create data visualizations and generate initial insights. This process creates general findings that establish the parameters of any data-driven hypotheses that will serve as the foundation of data models, including which data sets provide the most value.
  4. Model the data. With a basic understanding of the goal and available data sources, data engineers build models to structure and organize the data, bridging the gap between raw data and data ready for storage and retrieval by analytics applications.
  5. Evaluate the model. Here’s where you analyze. With the data model ready, teams can begin the analysis process to achieve the project’s initial goals. Data analysis can involve different forms of statistical analysis, including the use of programming languages and analytics tools.
  6. Deploy and monitor. Now it’s time to take action. With reports and visualizations ready, users can present findings to stakeholders to begin discussions on critical decisions. With analytics, recommendations stem from evidence found in data and presented clearly with visualizations—often with deeper insights than traditional or manual evaluation techniques.

Key Techniques in Analytics

The practice of analytics is built on a number of techniques established in the field of statistics, then brought to scale through the capabilities of machine learning. Some of the most common techniques used in analytics are as follows:

Understanding Machine Learning

At its core, machine learning is about finding connections and patterns within data. ML does this using techniques as straightforward as decision trees and as complex as neural networks, with their deeper layers capable of providing nonlinear relations in data. However, no matter the method, machine learning helps organizations improve cumbersome processes and delve into their data to fuel greater productivity and better decision-making.

Types of Machine Learning

A wide range of machine learning models exist depending on a project’s resources, goals, and limitations. Understanding the different types of machine learning techniques allows for teams to make the right choice for their project. Common types of machine learning include the following:

Steps in the Machine Learning Process

Regardless of your goals and parameters for your machine learning model, these projects often follow a standard process. Understanding this process before starting a project provides a roadmap for resource allocation and budgeting along the entire machine learning lifecycle.

Here are common steps for developing machine learning models.

  1. Identify the issue. What is the purpose of your machine learning model? More importantly, have others already produced models for that task, and if so, is one sufficient for your goals? Every project needs to be able to solve a problem, and the quality of that solution should define the project parameters from the starting point to metrics that dictate success.
  2. Collect and clean the data. To drive any machine learning project forward, you need data. That means identifying sources of training data similar to the data the trained model will encounter in general use then collecting and transforming that data into a unified, compatible format free from duplicates and errors. Skimping on this step could create biases that skew or even derail a project. Taking the time to carefully manage a project’s data set is an investment in ensuring success.
  3. Engineer for features. Not everything in a data set is necessary to train a machine learning model. A crucial early step for machine learning is identifying important parameters for the project, then curating data sets that feature diversity around those parameters. Feature engineering requires expert-led iteration, ultimately driving transformations by adding, removing, or combining data for a greater context that improves model accuracy.
  4. Select and train the model. Your project goals will determine a short list of machine learning techniques. Practical limitations, such as compute resources, project timeline, availability of quality data sources, and the experience of team members can narrow choices and ultimately dictate the best fit for a project. Once selected, the model iteratively trains on a curated training data set, refining outcomes and results until it achieves consistent accuracy.
  5. Evaluate the model. A successfully trained model delivers repeatable, explainable, and accurate results. Evaluate your trained model using real-world data to gauge how well it performs outside of its training data set. Evaluation tells teams how close the project is to meeting its original goals.
  6. Deploy and monitor. If a model successfully handles real-world test data on a consistent basis, it’s ready for a production environment. While deployment should happen only after certain benchmarks are met, that doesn’t mark the end of the model’s evolution. Teams must continuously monitor a model’s results to make sure it maintains accuracy, consistency, and other desired outcomes—and if results deviate, discover why.

Key Techniques in Machine Learning

Many machine learning techniques are in use, yet not every technique necessarily applies to the goals or limitations of a project. The trick to successful machine learning is knowing which technique to select based on your individual project parameters.

Popular techniques used in machine learning include the following:

Challenges in Analytics and Machine Learning

Machine learning and analytics rely on many of the same techniques. Because of that, both efforts face similar challenges, whether taken separately or as a combined “analytics-powered-by-machine-learning” project. Following are some common challenges faced by project teams.

Interpretability means understanding what the model did to come up with the particulars of its answer. Why did the GenAI system choose the words it chose in the order it chose them in summing up that board meeting? What calculations did it use to come with that 3% sales increase forecast? When AI cites its sources, it improves explainability. But as models become more complex, they are less and less interpretable.

Analytics and Machine Learning Best Practices

Analytics and machine learning share common practices regarding such factors as data sources, algorithms, and evaluation metrics. The following cover common practices for both analytics and machine learning.

  1. Define the Problem and the Metrics of Success:
    What is the purpose of your analytics project? That simple question is the foundation for everything that happens afterward. Know what problem you’re trying to solve, and decisions such as algorithm and data source selection cascade from there. That sets the starting point, but the finish line also needs definition. How will you measure success? Those two questions provide the broad framework for a project, and from there, teams can start filling in the details.

  2. Use High-Quality, Diverse Data Sets:
    The results of a project are only as good as the source data. Low-quality data sets with issues such as duplication and unrealistically uniform sources create problems—at best, skewing results, at worst, leading to wrong conclusions that cost the company time, money, and customers. For both analytics and AI, data sets must be current and reflect real-world conditions while bringing a range of relevant yet diverse perspectives.

  3. Choose the Right Algorithms and Model Architecture:
    Machine learning techniques have been developed for specific purposes. Anomaly detection systems are different from hierarchical clustering or object identification systems. Some ML methods require more processing power and may be poor choices for simpler applications. Similarly, analytics models have their best uses, too. It may be well worth trying out a few different algorithms on your data and comparing their performance.

  4. Regularize and Optimize Models:
    In ML, overfitting occurs when the model’s training set lacks the diversity that will be present in production use. If a model is highly trained on a limited data set, it may not be able to interpret input that’s different from its training set. Regularization seeks to eliminate overfitting and make the model more generally applicable. Optimization iteratively fine-tunes a model to ensure high accuracy.

  5. Communicate Results Clearly:
    The practices listed above involve technical elements of projects. However, one of the biggest potential keys to success is often overlooked: communicating results. Teams may be focused on fine-tuning models or auditing data sources and forget that key stakeholders need to know how a project is progressing. That requires clear communication with actionable metrics and a concise evaluation of “How’s it going?”

Use Cases and Applications of Analytics and Machine Learning

How do analytics and machine learning apply in the real world? As long as data exists, organizations in any industry can integrate analytics and machine learning. In fact, different departments, such as engineering, operations, marketing, and sales, can use these in different ways. The following cover just a handful of use cases showcasing the benefits of analytics and machine learning (PDF) across a variety of industries and functions.
