What is Deep Learning?
Definition
Deep learning is a type of machine learning that uses artificial neural networks, especially employing multiple layers when constructing these networks.
Motivation
Just like the human brain is composed of a complex network of neurons, deep learning also enhances performance by making the connections in artificial neural networks more complex. Similar to how the stimuli received by sensory cells are transmitted to the brain through the spinal cord, artificial neural networks pass calculations through multiple layers. These layers are called hidden layers.
Moreover, just as every person’s brain is different, based on the structure of the artificial neural network, there are problems it can solve well and problems it cannot. Therefore, constructing an artificial neural network that fits well with the problem and optimizing it is also a hot issue in this field.
