How Big Data is Revolutionizing Market Research
Difference between Machine Learning and Deep Learning.
The terms Machine Learning (ML) and Deep Learning (DL) are often used interchangeably, but they represent distinct concepts within the field of artificial intelligence (AI). Both play a crucial role in helping machines learn from data and make intelligent decisions, yet they differ in their methodologies, complexity, and applications.
What is Machine Learning?
Machine Learning is a subset of AI that enables systems to learn from data without being explicitly programmed. It focuses on developing algorithms to analyze data, identify patterns, and make predictions or decisions.
Key Features of Machine Learning:
- Requires structured data.
- Relies on feature extraction, where humans manually select the input features for models.
- Standard algorithms include decision trees, support vector machines (SVM), and random forests.
- Applications: Email spam detection, recommendation systems, and fraud detection.

What is Deep Learning?
Deep Learning is a specialized subset of ML that uses artificial neural networks inspired by the structure of the human brain. These networks can automatically discover intricate patterns in large amounts of data.
Key Features of Deep Learning:
- Can handle unstructured data such as images, audio, and text.
- Automates feature extraction, eliminating the need for manual intervention.
- Utilizes deep neural networks with multiple layers.
- Applications: Image recognition, natural language processing (NLP), and self-driving cars.
