In order to solve the language acquisition puzzle there are two basic problems one needs to address . The first is the so-called "logical problem of language acquisition" and the second is what I will refer to as the "developmental problem of language acquisition." The logical problem of language acquisition is the question, no doubt familiar to you all, of how we account for the richness, comp...

We present two-dimensional filter banks with directional vanishing moments. The directional-vanishing-moment condition is crucial for the regularity of directional filter banks. However, it is a challenging task to design orthogonal filter banks with directional vanishing moments. Due to the lack of multidimensional factorization theorems, traditional one-dimensional methods cannot be extended ...

Harnad (1994) identifies the symbol grounding problem as central to his distinction between cognition and computation. To Harnad computation is merely the systematically interpretable manipulation of symbols, while cognition requires that these symbols have intrinsic meaning that is acquired through transducers that mediate between a cogitator and the environment. We present a careful analysis ...

We measure the dollar risk exposure of U.S. industries by regressing stock portfolio returns on each industry against the returns on a broadly defined dollar index. The exposure estimates vary widely across different industries in both magnitudes and directions. We trace this large cross-sectional variation in dollar exposure to the industry’s average import and export activities. We find that ...

We analyze a novel agent-based model of a social network in which agents make contributions to others conditional upon the social distance, which we measure in terms of the “degrees of separation” between the two players. On the basis of a simple imitation model, the emerging strategy profile is characterized by high levels of cooperation with those who are directly connected to the agent and l...
