The frameworks of Deep Learning allow deep learning models to learn complex representations of data and make accurate predictions.
Business Intelligence is about refining information into intelligence to drive decisions and actions. Deep learning excels at processing high-dimensional data, such as images, videos, audio, and text, which contain a vast amount of information. Deep learning (DL) algorithms are built upon a specific algorithmic framework that allows them to learn complex patterns from data.
Artificial Neural Networks (ANNs): Deep learning is a subfield of machine learning heavily reliant on Artificial Neural Networks (ANNs). ANNs are inspired by the structure and function of the human mind. They consist of interconnected nodes (artificial neurons) arranged in layers.
Information flows through the network, and each neuron processes the information it receives from other neurons before passing it on. Through a process called backpropagation, the weights and biases associated with these connections are adjusted to improve the network's performance.
Multi-Layers in a Deep Neural Network: Deep learning models typically have multiple layers of artificial neurons stacked on top of each other. Each layer performs a specific transformation on the data, extracting increasingly complex features as it progresses through the network. The number of layers and the number of neurons in each layer are crucial hyperparameters that determine the model's capacity and complexity.
Activation Functions: Activation functions introduce non-linearity into the network. They determine how a neuron transforms the weighted sum of its inputs before passing it on to the next layer. Common activation functions include ReLU (Rectified Linear Unit) and sigmoid functions. These functions help the network learn complex patterns that wouldn't be possible with linear transformations alone.
Loss Functions: Loss functions measure how well the model's predictions differ from the actual ground truth values.The goal during training is to minimize the loss function by adjusting the weights and biases in the network. Common loss functions include mean squared error (MSE) for regression tasks and cross-entropy for classification tasks.
Optimizers: Optimizers are algorithms that update the weights and biases of the network based on the calculated loss. Popular optimizers include Stochastic Gradient Descent (SGD) and its variants. These algorithms iteratively adjust the weights in the direction that minimizes the loss function, gradually improving the model's performance.
Training Process: Deep learning models are trained on large datasets. During training, the model iteratively processes data points, calculates the loss, and updates its internal parameters using the chosen optimizer. This process continues until the model converges and achieves a satisfactory performance level.
Deep Learning Architectures: The specific arrangement of layers, activation functions, and other components defines the architecture of a deep learning model. Common deep learning architectures include:
-Convolutional Neural Networks (CNNs) for image recognition
-Recurrent Neural Networks (RNNs) for sequential data like text
-Generative Adversarial Networks (GANs) for generating new data.
The algorithmic framework of DL leverages artificial neural networks with multiple interconnected layers, applying activation functions and loss functions to guide the learning process through optimization algorithms. The frameworks of Deep Learning allow deep learning models to learn complex representations of data and make accurate predictions.
