Sügavõppevõrgud, or deep learning networks, are a class of machine learning algorithms inspired by the structure and function of the human brain. These networks are composed of multiple layers of interconnected nodes, or neurons, that process and transform data. The term "deep" refers to the number of layers in the network, which can range from a few to hundreds, allowing the model to learn complex representations of the input data.

Deep learning networks are particularly effective in tasks involving large amounts of unstructured data, such as images, speech, and text. They have achieved state-of-the-art performance in various domains, including computer vision, natural language processing, and speech recognition. Some of the most well-known architectures in deep learning include convolutional neural networks (CNNs) for image processing, recurrent neural networks (RNNs) for sequential data, and transformers for natural language understanding.

Training deep learning networks involves optimizing the weights of the neurons to minimize the difference between the predicted output and the actual target. This is typically done using backpropagation, an algorithm that calculates the gradient of the loss function with respect to each weight by applying the chain rule of calculus. Once trained, these networks can generalize well to new, unseen data, making them powerful tools for a wide range of applications.

However, deep learning networks also face challenges such as the need for large amounts of labeled data, computational resources, and the risk of overfitting. Researchers are actively working on addressing these issues to make deep learning more accessible and effective. Despite these challenges, deep learning continues to be a rapidly evolving field with significant potential for advancing artificial intelligence and its applications.
