Bilateral truncated Jacobi's identity
Recently, Andrews and Merca considered the truncated version of Euler’s pentagonal number theorem and obtained a non-negative result on the coefficients of this truncated series. Guo and Zeng showed the coefficients of two truncated Gauss’ identities are non-negative and they conjectured that the truncated Jacobi’s identity also has non-negative coefficients. Mao provided a proof of this conjec...
متن کاملThree-dimensional Bilateral Symmetry Bias in Judgments of Figural Identity and Orientation
The two experiments reported explored a bias toward symmetry in fudging identity and orientation of indeterminate twodimensional shapes Subjects viewed symmetric and asymmetric filled, random polygons and described "what each figure looks like" and its orientation Viewers almost universally interpreted the shapes as silhouettes of bilaterally symmetric three-dimensional (3-D) objects This assum...
متن کاملTruncated importance sampling
Importance sampling is a fundamental Monte Carlo technique. It involves generating a sample from a proposal distribution in order to estimate some property of a target distribution. Importance sampling can be highly sensitive to the choice of proposal distribution, and fails if the proposal distribution does not sufficiently well approximate the target. Procedures which involve truncation of la...
متن کاملIncremental Truncated LSTD
Balancing between computational efficiency and sample efficiency is an important goal in reinforcement learning. Temporal difference (TD) learning algorithms stochastically update the value function, with a linear time complexity in the number of features, whereas least-squares temporal difference (LSTD) algorithms are sample efficient but can be quadratic in the number of features. In this wor...
متن کاملTruncated Differentials and Skipjack
We consider a range of attacks on reduced-round variants of the block cipher Skipjack. In particular we concentrate on the role of truncated differentials and consider what insight they give us into the design and long-term security of Skipjack. An attack on the full 32 rounds of Skipjack remains elusive. However we give attacks on the first 16 rounds of Skipjack that can efficiently recover th...
