Erratum: SGDQN is Less Careful than Expected

The SGD-QN algorithm described in (Bordes et al., 2009) contains a subtle flaw that prevents it from reaching its design goals. Yet the flawed SGD-QN algorithm has worked well enough to be a winner of the first Pascal Large Scale Learning Challenge (Sonnenburg et al., 2008). This document clarifies the situation, proposes a corrected algorithm, and evaluates its performance.

Is spoken Danish less intelligible than Swedish?

The most straightforward way to explain why Danes understand spoken Swedish relatively better than Swedes understand spoken Danish would be that spoken Danish is intrinsically a more difficult language to understand than spoken Swedish. We discuss circumstantial evidence suggesting that Danish is intrinsically poorly intelligible. We then report on a formal experiment in which we tested the int...

When economic growth is less than exponential

This paper argues that growth theory needs a more general notion of “regularity” than that of exponential growth. We suggest that paths along which the rate of decline of the growth rate is proportional to the growth rate itself deserve attention. This opens up for considering a richer set of parameter combinations than in standard growth models. Moreover, it avoids the usual oversimplistic dic...

Symmetry is less than meets the eye

Symmetry is a ubiquitous feature in the visual environment and can be detected by a variety of species, ranging from insects through to humans [1,2]. Here we show it can also bias estimates of basic scene properties. Mirror (reflective) symmetry can be detected in as little as 50 ms, in both natural and artificial visual scenes, and even when embedded within cluttered backgrounds [1]. In terms ...
