Title: One-Shot Learning of Multi-Step Tasks from Observation via Activity Localization in Auxiliary Video,
Abstract: Due to burdensome data requirements, learning from demonstration often falls
short of its promise to allow users to quickly and naturally program robots.
Demonstrations are inherently ambiguous and inco... | [

Title: Concerning the Neural Code,
Abstract: The central problem with understanding brain and mind is the neural code
issue: understanding the matter of our brain as basis for the phenomena of our
mind. The richness with which our mind represents our environment, the
parsimony of genetic data, the tremendous efficiency... | [

Title: SPASS: Scientific Prominence Active Search System with Deep Image Captioning Network,

Title: Nonlinear Sequential Accepts and Rejects for Identification of Top Arms in Stochastic Bandits,

player has a limited budget to explore K arms (M<K), and once pulled, each arm
yields a reward drawn (independently) from a fixed, un... | [

Title: Thought Viruses and Asset Prices,

V$ to a destination $t\in V$ that includes all vertices specified by a set
$\mathscr{W}\subseteq V$: the \emph{waypoints}. Thi... | [

Title: A generalization of an identity due to Kimura and Ruehr,
Abstract: An identity stated by Kimura and proved by Ruehr, Kimura and others
stipulates that for any function $f$ continuous on $[-\frac{1}{2},
\frac{3}{2}]$ one has $$ \int_{-1/2}^{3/2} f(3x^2 - 2x^3) dx = 2 \int_0^1
f(3x^2 - 2x^3) dx. $$ We prove that t... | [
