Inspired by the seminal work on Stein Variational Inference [2] and Stein Variational Policy Gradient [3], we derived a method to generate samples from the posterior variational parameter distribution by explicitly minimizing the KL divergence to match the target distribution in an amortize fashion. Consequently, we applied this varational inference technique into vanilla policy gradient, TRPO ...

In this paper we consider the inventory problem with backorder such that both order and total demand quantities are triangular fuzzy numbers Q̃ = (q1, q0, q2), and R̃ = (r1, r0, r2) respectively, where q1 = q0−Δ1, q2 = q0+Δ2,r1 = r0−Δ3, r2 = r0+Δ4 such that 0 < Δ1 < q0, 0 < Δ2, 0 < Δ3 < r0, 0 < Δ4. Let s denote the maximum inventory quantity. Under conditions s ≤ q1 < q0 < q2 < r1 < r0 < r2, we f...

For a given set of queries (which are expressions in some query language) Q = {Q1, Q2, . . . Qk} and for another query Q0 we say that Q determines Q0 if – informally speaking – for every database D, the information contained in the views Q(D) is sufficient to compute Q0(D). Query Determinacy Problem is the problem of deciding, for given Q and Q0, whether Q determines Q0. Many versions of this p...

To reduce the phosphorus content in steel, CaO–SiO2–FexO–MgO-based dephosphorization slag was designed to clarify microscopic reaction behavior of phosphorus. In present study, Raman spectra final were measured and deconvoluted. The spectral analysis showed that P5+ ions removed from liquid iron existed form Q0(P) Q1(P) groups. According result, phosphate capacity distribution ratio (LP*) redef...

where X is the decision set and Q0, the distribution of ξ, is a probability distribution supported on [0, 1]. This kind of problem can be solved numerically or (in special cases) in closed form if we know the exact distribution of Q0. Unfortunately, in practice one rarely knows the exact distribution Q0. Instead, one often has only partial information about Q0, which may include limited distrib...

Let Q0 denote the rational numbers expanded to a meadow by totalizing inversion such that 0 = 0. Q0 can be expanded by a total sign function s that extracts the sign of a rational number. In this paper we discuss an extension Q0(s, √ ) of the signed rationals in which every number has a unique square root.
