Constructing an image classification system using strong, local invariant descriptors is time consuming and tedious, requiring many experimentations and parameter tuning to obtain an adequately performing model. Furthermore, training a system in a given domain and then migrating the model to a separate domain will likely yield poor performance. As computer vision systems become more prevalent in the academic, government, and private sectors, it is paramount that a framework to more easily construct these classification systems be created. In this work we present a rapidly deployable image classification system using multi-views, where each view consists of a set of weak global features. These weak global descriptors are computationally simple to extract, intuitive to understand, and require substantially less parameter tuning than their local invariant counterparts. We demonstrate that by combining weak features with ensemble methods we are able to outperform the current state-of-the-art methods or achieve comparable accuracy. Finally, we provide a theoretical justification for our ensemble framework that can be used to construct rapidly deployable image classification systems called "Ecosembles".

When deciding how to create a mobile application, developers can be faced with a large variety of technologies to choose from.  In the previous tutorial I demonstrated how a visual application builder, Sencha Architect, could be used for creating a cross-platform mobile HTML5 app built on the JavaScript framework Sencha Touch, simply by dragging and dropping components on to a canvas.

DreamFactory launches a new open-source platform for building mobile HTML5 and native apps.

This week, UMBC’s Erickson School is spearheading the Executive Director Leadership Institute (EDLI) at the annual conference of the Assisted Living Federation of America (ALFA) in Charlotte, North Carolina. The program has expanded from 40 to 200 participants in just one year. It offers a rigorous curriculum designed for rising community leaders in the senior living industry.

Chris Hollister, Southern Assisted Living co-founder and senior fellow at the Leadership Institute at the Erickson School, serves as EDLI 2013 co-leader; Erickson School Dean Judah Ronch serves on the EDLI faculty. Their curriculum will address topics from senior community culture to best practices for memory-impaired residents.
