Predicted value example
WebApr 22, 2024 · The lowest possible value of R² is 0 and the highest possible value is 1. Put simply, the better a model is at making predictions, the closer its R ² will be to 1. Example: … The classical approach is to evaluate the model’s output on all the test input and compute the average error rateaccording to one’s favorite metric. To give an example: imagine you are predicting the temperature tomorrow and your model has an average error rate of 5%, if your model says tomorrow’s temperature will … See more We generate two variables: x is our independent variable it takes values between 0 and 1 and yis the value we want to predict. We generate y according to the … See more Let’s make a neural network that predicts y based on x. We'll just use a single layer neural network. We’ll use tf.keras for this: After training this model for 200 … See more As promised, we are going to modify our model so that its output is not just one prediction but a prediction together with its confidence.
