Large-scale recognition problems with thousands of classes pose a particular challenge because applying the classifier requires more computation as the number of classes grows. The label tree model integrates classification with the traversal of the tree so that complexity grows logarithmically. In this paper, we show how the parameters of the label tree(More)
We introduce Segment-Phrase Table (SPT), a large collection of bijective associations between textual phrases and their corresponding segmentations. Leveraging recent progress in object recognition and natural language semantics, we show how we can successfully build a high-quality segment-phrase table using minimal human supervision. More importantly, we(More)
In this paper, we study the problem of answering visual analogy questions. These questions take the form of image A is to image B as image C is to what. Answering these questions entails discovering the mapping from image A to image B and then extending the mapping to image C and searching for the image D such that the relation from A to B holds for C to D.(More)
How can we know whether a statement about our world is valid. For example, given a relationship between a pair of entities e.g., `eat(horse, hay)', how can we know whether this relationship is true or false in general. Gathering such knowledge about entities and their relationships is one of the fundamental challenges in knowledge extraction. Most previous(More)
Environment feedback t = 0 t = 1 t = 2 t = 3 t = 4 t = H … Action Collision with wall Collision with Furniture No Collision Different Platforms time Fig. 1. We learn an autonomous indoor flight controller, (CAD) 2 RL, using a novel Collision Avoidance via Deep Reinforcement Learning algorithm which is entirely trained in a simulated environment constructed(More)
A scene category imposes tight distributions over the kind of objects that might appear in the scene, the appearance of those objects and their layout. In this paper, we propose a method to learn scene structures that can encode three main interlacing components of a scene: the scene category, the context-specific appearance of objects, and their layout.(More)
The natural immune system is composed of cells and molecules with complex interactions. Jerne modeled the interactions among immune cells and molecules by introducing the immune network. The immune system provides an effective defense mechanism against foreign substances. This system like the neural system is able to learn from experience. In this paper,(More)
