Caltech-256 Object Category Dataset
TL;DR: A challenging set of 256 object categories containing a total of 30607 images is introduced and the clutter category is used to train an interest detector which rejects uninformative background regions.
Proceedings ArticleDOI
Entropy-based active learning for object recognition
TL;DR: A novel, entropy-basedactive learningrdquo approach to sequentially acquire labeled data by presenting an oracle with unlabeled images that will be particularly informative when labeled, which can significantly reduce the overall number of training examples required to reach near-optimal performance.
Proceedings ArticleDOI
The rate adapting poisson model for information retrieval and object recognition
TL;DR: An alternative undirected graphical model suitable for modelling count data, called the "Rate Adapting Poisson" (RAP) model, is shown to generate superior dimensionally reduced representations for subsequent retrieval or classification.
Proceedings ArticleDOI
Combining generative models and Fisher kernels for object recognition
TL;DR: This work explores a hybrid generative/discriminative approach using 'Fisher kernels' by Jaakkola and Haussler (1999) which retains most of the desirable properties of generative methods, while increasing the classification performance through a discriminative setting.
Journal ArticleDOI
Computational Modeling of Retinotopic Map Development to Define Contributions of EphA-EphrinA Gradients, Axon-Axon Interactions, and Patterned Activity
TL;DR: A computational model of map development demonstrates that gradients of counter-repellents can establish a substantial degree of topographic order in the OT/SC, and that repellents present on RGC axon branches and arbors make a substantial contribution to map refinement.
