Statistical learning and machine learning are two powerful tools that help us make sense of data, but they have distinct approaches and applications.
Statistical learning relies on mathematical models and probability theory to make predictions and identify patterns in data. It's like using a recipe to bake a cake - you follow a set of established steps and ingredients to achieve a predictable outcome.
Machine learning, on the other hand, uses algorithms to learn from data and improve over time. This approach is more like trying to create a new recipe without a clear formula, and seeing what works best through trial and error.
In statistical learning, the goal is to identify the underlying relationships between variables, whereas machine learning aims to make accurate predictions and decisions based on complex patterns in data.

What Is
Statistical learning is a branch of statistics that focuses on building mathematical models to analyze and interpret data, emphasizing understanding underlying patterns, structure, and uncertainty while making inferences and predictions using formal statistical methods.
It's closely intertwined with machine learning, which is an artificial intelligence subset that enables computer systems to automatically learn and improve from experience without explicit programming, using algorithms to analyze data, identify patterns, and make data-driven decisions.
Statistical learning is the basis for machine learning algorithms, providing the underlying models that govern how a machine learning algorithm understands data. One example of this is a linear regression algorithm, which is a type of machine learning algorithm developed based on the principles of statistics.
Knowledge of statistics is critical when troubleshooting issues with machine learning algorithms, as it helps professionals understand why and how to address the underlying issue. Statistics expertise also paves the way for a variety of data careers, ranging from marketing analysis to data science.
The Elder Institute's research is an excellent example of how statistical learning can be applied to real-world problems, combining statistical modeling of diseases in animals with machine learning to automate the identification, verification, and sorting of new data.

Similarities and Differences
Both machine learning and statistical learning use historical data as input to predict new output values, but they vary in underlying assumptions and analyst intervention.
Statistical learning theory (SLT) is the foundation of machine learning, and understanding its guiding rules is crucial for data scientists. This is because a lack of understanding of the problem and underlying data assumptions can lead to biased and irrelevant results.
The similarities between machine learning and statistical modeling start with the assumption that past data can be used to predict the future. Both techniques leverage available data for generalization to a larger population.
Here's a comparison of the two fields:
In summary, while machine learning and statistical learning share some similarities, they have distinct differences in their focuses and methodologies.
Similarities Between
Machine learning and statistical modeling share some surprising similarities. Both techniques use historical data as input to predict new output values.
One key similarity is that both methods rely on the assumption that past data can be used to predict the future. This assumption is a fundamental principle in both machine learning and statistical modeling.
The variables used in analysis are also similar between the two techniques. In both machine learning and statistical modeling, variables are categorized into two types: dependent variables, also known as targets in machine learning, and independent variables, also known as features in machine learning.
Both machine learning and statistical modeling aim to generalize results to a larger population. This means that the available data is used to make predictions that can be applied to a broader context.
The loss and risk associated with model accuracy are also measured in a similar way. In statistical modeling, this is known as mean squared error (MSE), which is the difference between the predicted value and the actual value. In machine learning, the same concept is represented via a confusion matrix that evaluates a classification problem's accuracy.
Differences Between
Machine Learning and Statistical Learning have different focuses and methodologies. Machine Learning focuses on algorithm design for data-based decision-making without explicit programming, whereas Statistical Learning is centered on building mathematical models to understand and interpret data.
Statistical Learning models are more interpretable and often use simpler, linear models, whereas Machine Learning prioritizes optimizing predictive performance and computational efficiency.
Machine Learning does not require many assumptions and interventions when running algorithms in order to accurately predict studied outcomes, whereas Statistical Modeling is based on SLT and uses mathematical models and statistical assumptions to generate sample data and make predictions.

Machine Learning prioritizes optimizing predictive performance and computational efficiency, whereas Statistical Learning models are more interpretable and often use simpler, linear models.
Choosing a Modeling Approach
Machine learning algorithms are a preferred choice of technique versus statistical modeling under specific circumstances, data configurations, and outcomes needed.
The decision to lead with machine learning versus statistical modeling can be based on explicit criteria that can be weighed and ranked based on the desired outcome of the work.
Machine learning emphasizes prediction accuracy and performance metrics, such as precision, recall, and F1 score.
Statistical learning is more focused on model assumptions, hypothesis testing, and confidence intervals to understand the statistical significance and uncertainty in the model.
Collaboration and communication between data scientists, statisticians, and medical experts is crucial for designing successful research studies that provide valid, interpretable, and relevant results.
Machine learning foundations are based in statistical theory and learning, and a sound statistical background is essential to understand the nuances in the data and presented results.
Well-written machine learning code does not negate the need for an in-depth understanding of the problem, assumptions, and the importance of interpretation and validation.
Machine learning models can be highly complex and non-linear, using neural networks and deep learning techniques, which can lead to improved predictive performance but sometimes at the expense of interpretability.
Statistical learning models are more interpretable and often use simpler, linear models.
