Deep Learning Vs Machine Learning: What’s the difference

Machine learning (ML) is a subset of artificial intelligence (AI) that focuses on developing algorithms and models that allow computers to learn from and make predictions or decisions based on data.  Deep learning (DL) is a subfield of machine learning that specifically uses artificial neural networks with multiple layers to extract high-level representations and features from complex data.


In machine learning, features need to be manually extracted and selected from the data before feeding it into the algorithms.  Deep learning, on the other hand, learns hierarchical representations of the data by automatically extracting features from raw data, eliminating the need for manual feature engineering.

Data Representation

Deep learning excels when dealing with large-scale datasets with high-dimensional inputs. It can automatically learn intricate patterns and dependencies from vast amounts of data, leading to improved performance and accuracy.  Machine learning algorithms may struggle to handle complex datasets effectively without proper feature engineering.

Performance with Large Datasets

Deep learning models tend to be more complex than traditional machine learning models. Deep neural networks consist of multiple layers and a large number of parameters, making them computationally intensive to train.  Machine learning models, on the other hand, can be simpler and easier to interpret, making them suitable for scenarios where transparency and explainability are crucial.


Deep learning models often require substantial computational resources and specialized hardware, such as GPUs (Graphics Processing Units), to efficiently train and process the vast amount of data.  Machine learning algorithms can often run on standard hardware and may not require as much computational power.

Hardware and Computational Requirements

Machine learning heavily relies on feature engineering, which involves selecting and engineering relevant features from the data to improve model performance.  Deep learning, on the other hand, can automatically learn features from raw data, eliminating the need for extensive manual feature engineering.

Feature Engineering

Both machine learning and deep learning find applications in various domains. Machine learning is commonly used in areas such as regression, classification, clustering, and recommendation systems.  Deep learning excels in tasks like image and speech recognition, natural language processing, and computer vision, where large amounts of complex data are involved.

Application Areas

Deep learning models typically require a large amount of labeled training data to generalize well and achieve high performance.  Machine learning models can sometimes work effectively with smaller datasets and may not require as much labeled data.

Training Data Requirements

Machine learning models are often more interpretable than deep learning models. With machine learning, it's easier to understand and explain how the model arrived at a certain prediction or decision since the features and rules are explicitly defined.  Deep learning models, with their complex architectures, can be more challenging to interpret and understand.


Machine learning algorithms are generally easier to develop and implement compared to deep learning models.  Deep learning models require more expertise in neural network architectures, hyperparameter tuning, and computational resources to train and deploy successfully.

Development and Implementation

Understanding the differences between machine learning and deep learning is crucial in determining the most suitable approach for a given problem. While machine learning offers versatility and interpretability, deep learning excels in handling complex data and extracting intricate patterns.
