Understanding Machine Learning
Machine Learning involves creating models and algorithms that allow computers to analyze data and make predictions or take actions based on that data. ML algorithms are designed to learn from past experiences or examples and apply that knowledge to new, unseen data. This process is known as training, where the algorithm adjusts its parameters to produce accurate results.
**Machine Learning** can be divided into two main categories:
- Supervised Learning: In supervised learning, the algorithm is provided with labeled training data. It learns to map inputs to outputs based on these labels and can make predictions on unseen data.
- Unsupervised Learning: In unsupervised learning, the algorithm doesn’t have labeled data. It identifies patterns or structures in the data without specific guidance and can be used for tasks like clustering and anomaly detection.
*Machine Learning can handle a wide range of tasks, including image and speech recognition, recommendation systems, and predicting stock prices.*
Introducing Deep Learning
Deep Learning is a subset of Machine Learning that utilizes artificial neural networks to emulate the way the human brain works. It involves multiple layers of interconnected nodes (artificial neurons) that process data and extract features at different levels of abstraction. DL algorithms learn from large amounts of data to perform complex tasks with high accuracy.
**Deep Learning** is known for its ability to automatically extract relevant features from raw data, removing the need for manual feature engineering. This makes it particularly effective in dealing with unstructured data, such as images, audio, and text.
Deep Learning architectures include:
- Convolutional Neural Networks (CNNs) for image and video analysis.
- Recurrent Neural Networks (RNNs) for sequential data processing.
- Generative Adversarial Networks (GANs) for generating new data based on existing examples.
