With the adoption of pairings and binary trees where a number of leaves is the same as a number of time periods, we are assured that an updated secret key can not be used to recover any of its predecessors. This
To define such encoding, we assigned a numerical identification (ID) from a dense set to each node, and then we defined the encoding of an edge as the concatenation of the binary representations of the numerical IDs of the source and destination nodes. This edge encoding has the appealing ...
1995). Random forest is an ensemble of decisiontreesor it can be thought of as a forest of decision trees. Since random forest combines manydecision treemodels into one,
However, unlike RFs, ERTs build each tree from the complete learning sample without bootstrap and for each of the split candidates a discretization threshold is selected at random to define a split, instead of choosing the best cut-point based on the local sample. View chapter Book series ...

We already have a unique per-thread value, the thread id, which is a value in [0,m). Now, if we take the thread id and feed it into a mod-mLCG, each thread will still have a unique identifier, but the ordering will have changed pseudorandomly. Note that this LCG pro...

Let's assume that you have some condidential data and want to apply your data to some ML model which is provided by some third party service provider. If the ML model is a HE-based ML model, you can execute the model on the service provider's server without publishing the data to th...
leetcode:107. Binary Tree Level Order Traversal II 107. Binary Tree Level Order Traversal II Description Given a binary tree, return the bottom-up level order traversal of its nodes' values. (ie, from left to right, level by level from leaf to root). ......
where\(p_{D_1}(\cdot )\)and\(p_{D_2}(\cdot )\)represent the probability mass functions of\(D_1\)and\(D_2\), respectively. For two random variables\(X_1\)and\(X_2\), we write\(X_1 \,{\mathop {=}\limits ^{{\text {id}}}\,X_2\)when\(\varepsilon = 0\)i.e....
