Challenge Problems
Push your limits with advanced challenges
Consider a neural network where a neuron has three inputs with weights of 0.2, 0.5, and 0.3 respectively. If the corresponding inputs are 1, 2, and 3, calculate the output of the neuron if the bias is 0.1 and the activation function is a sigmoid.
💡 Hint: First find the weighted sum, then apply the sigmoid function.
Explain how altering the weights of a neuron might impact its output during the training of a neural network. Provide an example.
💡 Hint: Think about how changing the importance of inputs affects the overall decision-making process.
