Question
Which of the following is true for neural networks?
A. It has a set of nodes and connections
B. A node could be in an excited state or non-excited state
C. Each node computes it’s weighted input
D. All of the above
Answer
D. All of the above
Explanation
Neural networks has a set of nodes and connections where each node computes it’s weighted input and a node could be in an excited state or non-excited state. So all of the above is correct.
Neural networks are a fundamental component of artificial intelligence and machine learning, mimicking the way human brains process information.
Set of Nodes and Connections
Neural networks consist of interconnected nodes (also called neurons) organized into layers: an input layer, one or more hidden layers, and an output layer. Each node represents a computational unit that processes input data, and connections (or edges) between nodes represent the flow of information. These connections are characterized by weights that adjust during training to minimize errors in predictions.
Excited State or Non-Excited State
Each node in a neural network can exist in different states based on its activation function. When the weighted sum of inputs to a node exceeds a certain threshold, it enters an “excited” state (activating), allowing it to pass information to subsequent layers. Conversely, if the sum does not exceed this threshold, the node remains in a “non-excited” state and does not activate.
Weighted Input Computation
Each node computes its output based on a weighted sum of its inputs. This computation allows nodes to learn from data by adjusting weights through training algorithms such as backpropagation.
In summary, all statements regarding neural networks are accurate representations of their structure and functionality, confirming that option D is indeed correct. Understanding these fundamentals is crucial for anyone studying convolutional neural networks (CNNs) and their applications in various fields such as image recognition and natural language processing.
