What is the main topic of the video?
— The video is about using recurrent neural networks to predict what food a roommate will cook based on weather and previous meals.
How are neural networks represented?
— Neural networks are represented by nodes and arrows, where input vectors are multiplied by edges and added to produce output vectors.
What makes recurrent neural networks different from normal neural networks?
— Recurrent neural networks use the output as input for the next iteration, allowing inputs to come from previous outputs.
How are food and weather represented in the neural network?
— Food and weather are represented by vectors and matrices, with the food matrix multiplying a food vector to output a concatenation of the same food item and the next day's food item.
What is the purpose of using merge maps in the neural network?
— Merge maps use a nonlinear function to turn a vector into a one-hot encoded vector, which is then combined with another vector to produce a result, helping to extract the desired food item.
