To improve the recognition of weak similarities between proteins a method of aligning two sequence profiles is proposed. It is shown that exploring the sequence space in the vicinity of the sequence with unknown properties significantly improves the performance of sequence alignment methods. Consistent with the previous observations the recognition sensitivity and alignment accuracy obtained by...

The long-term fusion of vertical or horizontal disparities by vergence eye movements is known to evoke persistent changes in vertical and horizontal eye alignment. Adaptive changes in response to torsional disparities have not been well studied. Torsional eye position was measured binocularly with a video system before and after 90 min training periods in which subjects attempted to fuse cyclod...

This paper presents a 3-D model-based ATR algorithm which operates simultaneously on imagery from three heterogeneous, approximately boresight aligned, sensors. An iterative search matches models to range and optical imagery by repeatedly predicting detectable features, measuring support for these features in the imagery, and adjusting the transformations relating the target to the sensors in o...

This paper proposes and evaluates the k-greedy equivalence search algorithm (KES) for learning Bayesian networks (BNs) from complete data. The main characteristic of KES is that it allows a trade-off between greediness and randomness, thus exploring different good local optima when run repeatedly. When greediness is set at maximum, KES corresponds to the greedy equivalence search algorithm (GES...

Data-driven grapheme-to-phoneme conversion involves either (top-down) inductive learning or (bottom-up) pronunciation by analogy. As both approaches rely on local context information, they typically require some external linguistic knowledge, e.g., individual grapheme/phoneme correspondences. To avoid such supervision, this paper proposes an alternative solution, dubbed pronunciation by latent ...

System capacity is considered for a group of interfering users employing single user detection and multiple transmit and receive antennas for at Rayleigh fading channels with independent fading coeecients for each path. The focus is on the case where there is no channel state information at the transmitter, but channel state information is assumed at the receiver. It is shown that the optimum s...
