چکیده
The issue of how to improve the usability data publishing under differential privacy has become one top questions in field machine learning protection, and key solving this problem is allocate a reasonable protection budget. To solve problem, we design budget allocation algorithm based on out-of-bag estimation random forest. firstly calculates decision tree weights feature by protection. Secondly, statistical methods are introduced classify features into best set, pruned removable set. Then, pruning performed using set avoid trees over-fitting when constructing an ?-differential Finally, allocated proportionally We conducted experimental comparisons with real sets from Adult Mushroom demonstrate that not only protects security privacy, but also improves model classification accuracy availability.

Background The ensemble method random forests has become a popular classification tool in bioinformatics and related fields. The out-of-bag error is an error estimation technique which is often used to evaluate the accuracy of a random forest as well as for selecting appropriate values for tuning parameters, such as the number of candidate predictors that are randomly drawn for a split, referre...
متن کاملBearing Capacity of Shallow Foundations on Cohesionless Soils: A Random Forest Based Approach
Determining the ultimate bearing capacity (UBC) is vital for design of shallow foundations. Recently, soft computing methods (i.e. artificial neural networks and support vector machines) have been used for this purpose. In this paper, Random Forest (RF) is utilized as a tree-based ensemble classifier for predicting the UBC of shallow foundations on cohesionless soils. The inputs of model are wi...
