Incorporating curvature information into on-line learning

We analyse the dynamics of a number of second order on-line learning algorithms training multi-layer neural networks, using the methods of statistical mechanics. We first consider on-line Newton's method, which is known to provide optimal asymptotic performance. We determine the asymptotic generalization error decay for a soft committee machine, which is shown to compare favourably with the result for standard gradient descent. Matrix momentum provides a practical approximation to this method by allowing an efficient inversion of the Hessian. We consider an idealized matrix momentum algorithm which requires access to the Hessian and find close correspondence with the dynamics of on-line Newton's method. In practice, the Hessian will not be known on-line and we therefore consider matrix momentum using a single example approximation to the Hessian. In this case good asymptotic performance may still be achieved, but the algorithm is now sensitive to parameter choice because of noise in the Hessian estimate. On-line Newton's method is not appropriate during the transient learning phase, since a suboptimal unstable fixed point of the gradient descent dynamics becomes stable for this algorithm. A principled alternative is to use Amari's natural gradient learning algorithm and we show how this method provides a significant reduction in learning time when compared to gradient descent, while retaining the asymptotic performance of on-line Newton's method.

Enfermedades y muerte de Charles Darwin

Charles Darwin nació en Shrewsbury, Inglaterra, el 12 de febrero de 1809. Tuvo excelente salud, hasta su regreso, en 1836, del viaje alrededor del mundo con el Beagle. A partir de ese momento comenzó a manifestar cefaleas, palpitaciones, temblores, caries y paradentosis, catarros respiratorios, artritis, forúnculos, puntos negros en la visión, mareos, dolores abdominales, náuseas, vómitos, flatulencias, insomnio, accesos de furia, depresión y períodos de extremo agotamiento. Más allá de mejorías temporarias, estos síntomas se manifestaron durante los últimos 45 años de su vida, a pesar de lo cual pudo encontrar la entereza suficiente como para publicar 14 libros, entre ellos el genial El origen de las especies. Los diagnósticos más probables puestos a consideración por los distintos investigadores fueron un trastorno bipolar asociado a una herencia psicopatológica y la enfermedad de Chagas, que este ilustre personaje pudo haber contraído en Sudamérica. Finalmente, el 19 de abril de 1882, Darwin falleció muy probablemente a consecuencia de una patología vascular coronaria y cerebral. Sus restos se encuentran en la abadía de Westminster, junto a los de Isaac Newton.

Between the rose and the shoulders of giants

The following are thoughts on 2 of the most well-known phrases in the English language, recognized as universal academic icons. That of Juliet Capuleto’s in Act II, scene II, “The Balcony”, in the immortal work of William shakespeare’s Romeo and Juliet about “A rose by any other name”, and “On the shoulders of giants”, traditionally attributed to Isaac Newton, the discoverer of the Mechanical Universal Laws, including that of Universal Law of Gravitation, in the 17th Century, but in reality first said by the humanistic philosopher and theologist Bernard of Chartres in the 12th Century

Is financial instability male-driven? Gender and cognitive skills in experimental asset markets

The hypothesis that price stability would reliably increase with the fraction of women operating in financial markets has been frequently suggested in policy discussions. To test this hypothesis we conducted 10 male-only, 10 female-only and 10 mixed-gender experimental asset markets, and compared the effects of gender composition, confidence, risk attitude and cognitive skills. Male and female markets have comparable volatility and deviations from fundamentals, whereas mixed-gender markets are substantially more stable. On the other hand, higher average cognitive skills of the group are associated with reduced market volatility. Individual-level analysis shows that subjects with higher cognitive skills trade at prices closer to fundamental values and earn significantly higher profits; similarly, mixed markets exhibit lower mispricing, particularly for traders with lower cognitive skills. Our results are demonstrated to hold in other experimental asset market studies, suggesting that a mixed-gender composition reduces mispricing across different types of asset markets.
