Machine Learning vs AI
What are the key differences and benefits? This guide provides definitions and practical advice to help you understand these concepts as you evaluate AI vs machine learning for your organization.
Machine Learning vs AI
Like a hammer in a toolbox, machine learning (ML) is a specific tool within the broader scope of artificial intelligence (AI). ML is a technique that focuses on developing algorithms and models for learning and adapting to tasks and data. Artificial intelligence encompasses a wide range of techniques and aims to create intelligent machines capable of human-like intelligence.
As the data in your organization expands in both complexity and size, the integration of automated and intelligent systems becomes crucial for you to streamline tasks, extract value, and derive actionable insights that lead to improved outcomes.
What is Machine Learning?
Machine learning is a subset of artificial intelligence focused on the development of algorithms and models that enable computers to learn and make predictions or decisions without being explicitly programmed. So, instead of relying on your instructions, ML systems learn from data and improve their performance over time through experience.
The process typically requires you to feed large amounts of data into a machine learning algorithm. Typically, a data scientist builds, refines, and deploys your models. However, with the rise of AutoML (automated machine learning), data analysts can now perform these tasks if the model is not too complex.
The ML algorithm analyzes and identifies patterns, relationships, and trends within the data and then uses these insights to build a mathematical model that can make predictions, can power predictive analytics, or take actions when presented with new, unseen data.
Key ML techniques:
- Supervised Learning: Training a model using labeled data, where the desired output is known, to predict or classify new unseen examples.
- Unsupervised Learning: Discovering patterns and structures within unlabeled data without explicit guidance.
- Semi-Supervised Learning: Combining labeled and unlabeled data to train a model, leveraging both supervised and unsupervised techniques.
- Reinforcement Learning: Teaching an agent to learn optimal behaviors by receiving rewards or punishments based on its actions in an environment.
- Transfer Learning: Utilizing knowledge learned from one task or domain to improve performance on a different but related task or domain.
- Deep Learning: Employing neural networks with multiple layers to learn complex patterns and representations from data.
- Ensemble Learning: Combining multiple models to make predictions or decisions, often resulting in improved accuracy and robustness.
- Active Learning: Interactively selecting and labeling the most informative data instances for training, optimizing the learning process.
- Online Learning: Continuously updating and refining a model as new data arrives in a sequential manner.
- Feature Engineering: Transforming and selecting relevant features from raw data to improve the performance and interpretability of models.
Machine learning has a wide range of applications, including image and speech recognition, natural language processing, recommendation systems, fraud detection, prescriptive analytics, and autonomous vehicles. It plays a crucial role in enabling AI systems to adapt, improve, and perform complex tasks with minimal human intervention.

How ML and AI Work Together
Among the many AI techniques described above, machine learning has proven to be especially effective in a wide range of applications. This is why ML has gained such popularity and become a central component of many AI implementations.
In this representation of AI vs machine learning vs deep learning, AI is the broadest concept, with machine learning (ML) as a subset of AI. Within ML, there are neural networks, which are computational models with interconnected artificial neurons. And deep learning refers to a specific type of neural network architecture which has multiple layers for hierarchical representation learning. So, deep learning is a subset of neural networks, which in turn is a subset of ML, and ML is a subset of AI.
Here’s how you’d incorporate an ML model in your artificial intelligence system:
- System Setup: Build an AI system using machine learning and other techniques.
- Problem Definition: Clearly define the problem you aim to solve and determine if it’s suitable for an ML approach.
- Data Collection: Gather relevant data that’s representative of the problem domain and ensure it is properly labeled and structured.
- Data Exploration: Review your raw dataset to uncover characteristics and initial patterns for further analysis. This will help you understand the size and quality of your data, detect outliers or anomalies, and identify potential relationships among data elements, files, and tables.
- Data Preprocessing: Clean the data by handling missing values, outliers, and performing transformations or feature engineering to make it suitable for training.
- Model Selection: Choose an appropriate ML algorithm or model architecture based on the problem type, available data, and performance requirements.
- Model Training: Split the data into training and validation sets, feed it to the chosen algorithm/model, and iteratively adjust the model's parameters to optimize performance.
- Model Evaluation: Assess the trained model's performance using appropriate evaluation metrics on the validation set to ensure it meets the desired criteria.
- Adjust Hyperparameters: Fine-tune the model by adjusting hyperparameters (e.g., learning rate, regularization) through techniques like grid search or random search to improve performance.
- Model Validation: Test the final model on a separate, unseen test dataset to obtain a reliable estimate of its performance.
- Deployment: Integrate the trained model into a production environment, which may involve implementing it within a software system such as augmented analytics, API, or cloud platform.
- Monitoring and Maintenance: Continuously monitor your model's performance in the deployed environment, retraining or updating it as necessary to account for changing data patterns or evolving requirements.
- Iterative Improvement: Gather user feedback, collect new data, and periodically re-evaluate and refine your ML model to enhance its performance and address any limitations.
These steps may not necessarily be linear and may involve iterations or adjustments based on your specific project requirements and feedback received during the development process.
