Understanding the Basics of Deep Learning

Deep learning is a subset of machine learning that utilizes artificial neural networks to model and solve complex problems. Neural networks are designed to mimic the human brain and learn from data. In deep learning, the networks are typically composed of multiple layers, with each layer extracting increasingly abstract features from the input data.

The key concepts and terminology in deep learning include:

  • Artificial neural networks: These are computational models inspired by the structure and function of biological neural networks. They consist of interconnected nodes, or artificial neurons, that process and transmit information.
  • Activation functions: These are mathematical functions applied to the output of each neuron to determine its activation level. Common activation functions include the sigmoid, ReLU (rectified linear unit), and tanh (hyperbolic tangent) functions.
  • Loss functions: These are mathematical functions used to measure the difference between the predicted output of a neural network and the actual output. The goal of training a neural network is to minimize the loss function.
  • Optimization algorithms: These are methods used to update the weights and biases of a neural network during training in order to minimize the loss function. Common optimization algorithms include gradient descent, Adam, and stochastic gradient descent.
  • Convolutional neural networks (CNNs): These are a type of neural network commonly used for image and video recognition tasks. They consist of multiple convolutional layers that learn to detect and classify patterns in data.
  • Recurrent neural networks (RNNs): These are a type of neural network designed to handle sequential data, such as time series or natural language. They consist of loops that allow information to persist and be processed over time.
  • Transfer learning: This is the process of using a pre-trained neural network as a starting point for a new task. By leveraging the knowledge and features learned from a large dataset, transfer learning can significantly reduce the amount of training required for a new task.

The Learning Curve of Deep Learning
