BACKGROUND Many patients who have involuntary weight loss have cancer. The Hernandez prediction rule includes 5 variables (elevated levels of alkaline phosphatase and lactate dehydrogenase, low albumin, high white blood cell count, and age >80 years).

متن کاملPrediction strategies without loss
Consider a sequence of bits where we are trying to predict the next bit from the previous bits. Assume we are allowed to say ‘predict 0’ or ‘predict 1’, and our payoff is +1 if the prediction is correct and −1 otherwise. We will say that at each point in time the loss of an algorithm is the number of wrong predictions minus the number of right predictions so far. In this paper we are interested...
