## Definition of Deep Learning and Neural Network

Deep **Learning** is a type of **machine** learning that is designed **to** learn complex representations of **data** through the use of artificial neural networks with multiple layers, hence the term “deep”. These layers enable the network to automatically learn hierarchical representations of data, allowing **it** to **perform** tasks such **as** image and speech **recognition**, natural language processing, and decision-making.

Deep Learning **algorithms** can be **used** **in** a wide variety of **applications** such as self-driving cars, recommendation systems, fraud detection, and more. They require large amounts of data to train, but once trained, they can make predictions on new data with high accuracy.

A typical workflow **for** using Deep Learning involves the following steps:

**Data preparation:****This**involves preparing the dataset that the Deep Learning model will be trained on.**Model definition:**This involves defining the structure of the Deep Learning model, such as the number of layers, the number of neurons in each layer, and the activation**functions**used in each**neuron**.**Model**This involves feeding the prepared data into the Deep Learning model and adjusting the weights and biases of the neurons through a**training**:**process**known as backpropagation.**Model evaluation:**This involves testing the Deep Learning model’s performance on a separate dataset to ensure that it is accurate and reliable.

Deep Learning has various advantages, such as its ability to learn and generalize from large amounts of data, make predictions on new and unseen data, and learn complex and non-linear **relationships**. However, they also **have** some disadvantages, such as the need for large amounts of data, computational resources, and **time** for training, as **well** as the potential for overfitting the model to the training data.

## Differences Between Deep Learning and Neural Network

The main differences between Deep Learning and Neural Networks **are**:

**Complexity:**Neural Networks typically have only a few hidden layers, while Deep Learning models can have hundreds of hidden layers. The additional layers allow Deep Learning models to learn hierarchical representations of data and make more accurate predictions on complex problems.**Data requirements:**Deep Learning models require significantly more data than Neural Networks to train effectively. This is because the additional layers in Deep Learning models require a large amount of data to learn complex features and generalize patterns.**Computation resources:**Deep Learning models require significantly more computational resources than Neural Networks. This is because the additional layers in Deep Learning models require more processing**power**to train effectively.**Performance:**Deep Learning models often outperform Neural Networks on complex problems such as image recognition and natural language processing. This is because Deep Learning models are better at learning complex representations of data.**Interpretability:**Neural Networks are typically more interpretable than Deep Learning models,**which**can be highly complex and difficult to interpret. This is because Neural Networks have fewer layers and simpler architectures.**Time to train:**Deep Learning models require significantly more time to train than Neural Networks. This is because the additional layers in Deep Learning models require more iterations to converge to an optimal**solution**.

Deep Learning models are better suited for complex problems that require a high **degree** of accuracy, while Neural Networks are better suited for simpler problems that require faster training and easier interpretability.
