Neural Networks Practice Exam

Neural networks refers to a specific category of machine learning models which are based on the structure and function of the human brain. They consist of interconnected nodes, or neurons, arranged in layers. Information flows through the network from the input layer, where data is fed into the network, through hidden layers, where computation occurs, to the output layer, which produces the final result. Connection amongst neurons is assigned an weight as per the strength of the connection. During training, the network adjusts these weights based on the input data and the desired output, a process known as learning. Neural networks are capable of learning complex patterns in data and are used in a variety of applications, including image and speech recognition, natural language processing, and autonomous driving.
Why is Neural Networks important?

• Pattern Recognition: Neural networks excel at recognizing patterns in data, making them valuable for tasks such as image and speech recognition.
• Non-Linearity: They can model complex, non-linear relationships in data, which is often impossible with traditional statistical models.
• Adaptability: Neural networks can adapt to new data and changing environments, making them suitable for dynamic and evolving systems.
• Parallel Processing: They can perform computations in parallel, enabling faster processing of large amounts of data.
• Fault Tolerance: Neural networks are robust to noisy data and can still make accurate predictions even when some data is missing or incorrect.
• Feature Extraction: They can automatically extract relevant features from raw data, reducing the need for manual feature engineering.
• Scalability: Neural networks can scale to handle large and complex datasets, making them suitable for big data applications.
