A Neighbourhood-Aware Differential Privacy Mechanism for Static Word Embeddings
Danushka Bollegala, Shuichi Otake, Tomoya Machide +1
We propose a Neighbourhood-Aware Differential Privacy (NADP) mechanism considering the neighbourhood of a word in a pretrained static word embedding space to determine the minimal…
Computations about formal multiple zeta spaces defined by binary extended double shuffle relations
Tomoya Machide
The formal multiple zeta space we consider with a computer is an -vector space generated by formal symbols for a given weight , where the symbols satisfy…
Query Obfuscation Semantic Decomposition
Danushka Bollegala, Tomoya Machide, Ken-ichi Kawarabayashi
We propose a method to protect the privacy of search engine users by decomposing the queries using semantically \emph{related} and unrelated \emph{distractor} terms. Instead of a s…
A formula for systems of Boolean polynomial equations and applications to computational complexity
Tomoya Machide
It is known a method for converting a system of Boolean polynomial equations to a single Boolean polynomial equation with less variables. In this paper, we show a formula for syste…
Identity involving symmetric sums of regularized multiple zeta-star values
Tomoya Machide
An identity involving symmetric sums of regularized multiple zeta-star values of harmonic type was proved by Hoffman. In this paper, we prove an identity of shuffle type. We use Be…
Use of the generating function to generalize the sum formula for quadruple zeta values
Tomoya Machide
In the present paper, we prove an identity for the generating function of the quadruple zeta values. Taking homogeneous parts on both sides of the identity and substituting appropr…
