Differences between ML and DL
Machine Learning (ML) is a subset of AI that focuses on developing algorithms capable of learning from and making predictions or decisions based on data. The algorithms used in ML are based on statistical models that generalize patterns from existing data.
ML algorithms work by first being trained on a labeled dataset, where the input data and desired output are provided. The algorithm learns patterns and relationships from this training data, allowing it to make predictions or decisions on new, unseen data.
One interesting aspect of ML is that it can handle a wide range of problems, from regression to classification and clustering. It can be applied to various domains, such as finance, healthcare, and marketing.
*ML algorithms can handle a variety of problem types, including regression, classification, and clustering.
Deep Learning (DL), on the other hand, is a subset of ML that focuses on creating artificial neural networks capable of deep learning, similar to how the human brain processes information. DL algorithms are designed to automatically learn hierarchical representations of data, allowing them to extract more complex features and patterns.
DL algorithms work by stacking multiple layers of artificial neurons, also known as artificial neural networks. Each layer learns to recognize specific patterns in the data, and the information flows through the network, enabling the model to make complex decisions.
One interesting aspect of DL is its ability to automatically learn features from raw data without explicit feature engineering, which can save time and effort in complex problems.
