What is a neural network?

A neural network is defined as a computational model inspired by biological neural networks. This phenomenon is rooted in the way that human brains operate, where interconnected neurons work together to process information and recognize patterns. In the context of computational models, neural networks consist of layers of interconnected nodes (or artificial neurons) that transform input data into output responses in a hierarchical manner.

The fundamental design of neural networks allows them to learn from data through a process called training, where they adjust the connections, or weights, between nodes based on the errors in their predictions. This capability to learn complex relationships and features within the data makes neural networks particularly powerful in tasks such as image recognition, natural language processing, and various other applications in machine learning and artificial intelligence.

The other options, while related to data and analytics in various ways, do not accurately define what a neural network is. Data cleaning involves preparing raw data for analysis, data storage systems pertain to how data is organized and stored, and frameworks for data visualization relate to how data is represented graphically. These options describe different concepts and tools in data handling but do not capture the essence of what a neural network represents in computational modeling.
