We further study the incidence relations that arise from the various subtowers, known as Baby Monster, which exist within the R3\mathbb{R}^{3}-Monster Tower. This allows us to complete the RVTRVT class spelling rules. We also present a method of calculating the various Baby Monster that appear within the Monster Tower.

We present Listen, Attend and Spell (LAS), a neural network that learns to transcribe speech utterances to characters. Unlike traditional DNN-HMM models, this model learns all the components of a speech recognizer jointly. Our system has two components: a listener and a speller. The listener is a pyramidal recurrent ne…

There are two themes in the present paper. The first one is spelled out in the title, and is inspired by an attempt to find an analogue of Hersch-Yang-Yau estimate for lambda1lambda_1 of surfaces in symplectic category. In particular we prove that every split symplectic manifold T4timesMT^4 times M admits a compatible Riemannian …
