The model has trained ?too well? and is now, well, fit too closely to the training dataset; The model is too complex (i.e. too many features/variables compared to the number of observations) The model will be very accurate on the training data but will probably be very not accurate on untrained or new data WebSupervised learning: predicting an output variable from high-dimensional observations¶. The problem solved in supervised learning. Supervised learning consists in learning the link between two datasets: the observed data X and an external variable y that we are trying to predict, usually called “target” or “labels”. Most often, y is a 1D array of length n_samples. danbury fireworks
