I'm in the process of attempting to learn to work with neural networks in R. As a learning problem, I've been using the following problem over at Kaggle : Don't worry, this problem is specifically designed for people to learn with, there's no reward tied to it. I started with a simple logistic regression, which was great for getting my feet wet. Now I'd like to learn to work with neural networks. My training data looks like this (Column:Row): - survived: 1 - pclass: 3 - sex: male - age: 22.0 - sibsp: 1 - parch: 0 - ticket: PC 17601 - fare: 7.25 - cabin: C85 - embarked: S My starting R code looks like this: > net <- neuralnet(survived ~ pclass + sex + age + sibsp + parch + ticket + fare + cabin + embarked, train, hidden=10, threshold=0.01) When I run this line of code I get the following error: Error in neurons[[i]] %*% weights[[i]] : requires numeric/complex matrix/vector arguments I understand that the problem is in the way I'm presenting my input variables but I'm too much of a novice to understand what I need to do to correct this. Can anyone help? Thanks!
