Long-term weight loss maintenance [PDF]
The American Journal of Clinical Nutrition, 2005 There is a general perception that almost no one succeeds in long-term maintenance of weight loss. However, research has shown that approximately 20% of overweight individuals are successful at long-term weight loss when defined as losing at least 10% of initial body weight and maintaining the loss for at least 1 y. The National Weight Control Registry

Balancing Between Over-Weighting and Under-Weighting in Supervised Term Weighting
CoRR, 2016 Supervised term weighting could improve the performance of text categorization. A way proven to be effective is to give more weight to terms with more imbalanced distributions across categories. This paper shows that supervised term weighting should not just assign large weights to imbalanced terms, but should also control the trade-off between over ...
