Picasso: A Modular Framework for Visualizing the Learning Process of Neural Network Image Classifiers

Picasso is a free open-source (Eclipse Public License) web application written in Python for rendering standard visualizations useful for analyzing convolutional neural networks. Picasso ships with occlusion maps and saliency maps, two visualizations which help reveal issues that evaluation metrics like loss and accuracy might hide: for example, learning a proxy classification task. Picasso works with the Tensorflow deep learning framework, and Keras (when the model can be loaded into the Tensorflow backend). Picasso can be used with minimal configuration by deep learning researchers and engineers alike across various neural network architectures. Adding new visualizations is simple: the user can specify their visualization code and HTML template separately from the application code.Comment: 9 pages, submission to the Journal of Open Research Software, github.com/merantix/picass

A posteriori analysis of Chorin-Temam scheme for Stokes equations

We consider Chorin-Temam scheme (the simplest pressure-correction projection method) for the time-discretization of an unstationary Stokes problem. Inspired by the analyses of the Backward Euler scheme performed by C.Bernardi and R.Verf\"urth, we derive a posteriori estimators for the error on the velocity gradient in L2 norm. Our invesigation is supported by numerical experiments

Status of the PICASSO Project

The Picasso project is a dark matter search experiment based on the superheated droplet technique. Preliminary runs performed at the Picasso Lab in Montreal have showed the suitability of this detection technique to the search for weakly interacting cold dark matter particles. In July 2002, a new phase of the project started. A batch of six 1-liter detectors with an active mass of approximately 40g was installed in a gallery of the SNO observatory in Sudbury, Ontario, Canada at a depth of 6,800 feet (2,070m). We give a status report on the new experimental setup, data analysis, and preliminary limits on spin-dependent neutralino interaction cross section.Comment: 3 pages, 2 figures.

The ‘Right’ Price for Art Collectibles. A Quantile Hedonic Regression Investigation of Picasso Paintings

Different art objects are likely to be priced by means of different systems of hedonic characteristics; more precisely, different evaluation procedures for high and low price items are often postulated. However, the empirical evidence on this point is scant. The main purpose of this paper is to fill this gap by using the quantile hedonic regression approach. The empirical evidence, based on a data set of 716 Picasso paintings sold at auction worldwide, highlights the critical role of the price classes in determining the evaluation criteria of art items.hedonic price; auction; quantile regression; painting; Picasso

Silencio, abuso y locura: Picasso en Art & Lies, de Jeanette Winterson

In Art & Lies (1994), Jeanette Winterson presents three characters who are alter egos of Handel, Picasso, and Sappho. This article focusses on Picasso as an alter ego not only of Pablo Picasso but also of the character itself, whose birth name is Sophia, and of Pablo Picasso’s lovers, who were silenced, abused, and driven to madness like Winterson’s Picasso. The main aspects taken into account are the fact that the character is silenced by her family and that she is sexually abused by her brother in order to understand that her journey towards becoming the madwoman in the attic is induced by the harmful context that she is surrounded by in the same way that occurred to Pablo Picasso’s lovers and to Bertha Mason in Jane Eyre.En Art & Lies (1994), Jeanette Winterson presenta tres personajes que son alter egos de Handel, Picasso y Safo. Este artículo se centra en Picasso no solo como alter ego de Pablo Picasso, sino también del mismo personaje de Picasso, cuyo nombre de pila es Sophia, y de las amantes de Pablo Picasso, que fueron silenciadas, abusadas y llevadas a la locura como ocurre con el personaje de Picasso de Winterson. Los aspectos principales que se han tenido en cuenta son el hecho de que el personaje es silenciado por su familia y que su hermano abusa sexualmente de ella para así entender que su camino hacia convertirse en la loca del desván se origina en el contexto dañino que la rodea, de la misma forma que ocurrió con las amantes de Picasso y con Bertha Mason en Jane Eyre
