Deep learning vs. machine learning for dummies

What is Machine Learning?

Machine learning (ML) is a subset of artificial intelligence that focuses on enabling machines to learn from and make decisions based on data, without being explicitly programmed. In other words, ML algorithms allow computers to ‘learn’ from data and improve their performance over time.

There are three main types of machine learning:

  1. Supervised Learning: The algorithm is trained using labeled data, which consists of input-output pairs. The algorithm learns to map inputs to outputs by minimizing the difference between predicted and actual outputs.
  2. Unsupervised Learning: The algorithm is not provided with labeled data, and it must find patterns, relationships, or groupings in the input data on its own.
  3. Reinforcement Learning: The algorithm learns through trial and error, receiving feedback in the form of rewards or penalties for its actions.

What is Deep Learning?

Deep learning (DL) is a subfield of machine learning that focuses on neural networks with many layers, also known as deep neural networks.

These networks are capable of learning complex patterns, representations, and abstractions from large amounts of data. While deep learning is a type of machine learning, not all machine learning methods are based on deep learning.

Deep neural networks consist of multiple layers of interconnected nodes or neurons, with each layer responsible for learning different features or representations. The layers in a deep neural network can be categorized as follows:

  1. Input Layer: This layer receives the raw input data and passes it on to the subsequent layers.
  2. Hidden Layers: These layers are responsible for processing and learning features from the input data.
  3. Output Layer: This layer produces the final output or prediction.

Deep Learning vs. Machine Learning: Key Differences

  1. Complexity: Deep learning algorithms are more complex than traditional machine learning algorithms, as they involve multiple layers of neural networks. Machine learning, on the other hand, involves a variety of techniques such as decision trees, support vector machines, and clustering, which can be simpler in comparison.
  2. Data Requirements: Deep learning typically requires large amounts of data to achieve high performance, while traditional machine learning methods can work well with smaller datasets.
  3. Computational Power: Deep learning algorithms require significant computational power and resources, often relying on GPUs for faster processing. Traditional machine learning algorithms can often be run on standard CPUs.
  4. Feature Engineering: In traditional machine learning, selecting and extracting the right features from the data is crucial for the success of the model. Deep learning, however, automatically learns features and representations from the data, eliminating the need for manual feature engineering.
  5. Interpretability: Machine learning models, especially simpler ones, can be more interpretable and easier to understand than deep learning models, which are often seen as “black boxes” due to their complexity.


Deep learning and machine learning are both subfields of artificial intelligence, with deep learning being a specialized type of machine learning.

While deep learning can solve more complex problems and automatically learn features from data, it requires larger datasets and more computational power than traditional machine learning methods.

Understanding the differences between these two approaches is crucial for choosing the right technique for your specific problem and dataset.
