Large margin nearest neighbor classification (LMNN) is a popular technique to learn a metric that improves the accuracy of a simple knearest neighbor classifier via a convex optimization scheme. However, the optimization problem is convex only under the assumption that the nearest neighbors within classes remain constant. In this contribution we show that an iterated LMNN scheme (multi-pass LMN...

This information-only contribution suggests some configurations in which gigabit per second DSL (GDSL) is feasible on lengths of 150 to 300 meters of 4 twisted pair. Basically the full binder capacity of 4 drop wires is examined with 6 dB of margin and the usual 4 dB of coding gain to find that rates that exceed 1 Gbps are possible in a DSL of 300 meters or less. Before too much surprise, one s...

Current statistical models for structured prediction make simplifying assumptions about the underlying output graph structure, such as assuming a low-order Markov chain, because exact inference becomes intractable as the tree-width of the underlying graph increases. Approximate inference algorithms, on the other hand, force one to trade off representational power with computational efficiency. ...

Three approaches have been taken to the study of submarine debris flows. 1) Measurements laterally constrained debris flow dynamics and pore pressure variation have been performed in the “Fish Tank” facility. 2) The dynamics of unconfined debris flows have been studied using the “Main Channel.” 3) A numerical model of muddy debris flows is being extended to a) sandy debris flows and b) the rewo...

Much attention has been paid to the theoretical explanation of the empirical success of AdaBoost. The most influential work is the margin theory, which is essentially an upper bound for the generalization error of any voting classifier in terms of the margin distribution over the training data. However, important questions were raised about the margin explanation. Breiman (1999) proved a bound ...

participation can be defined as a decision making process influencing on life. this term has been used and discussed more or jess by other scholars but recently it has got new versions of application. one of the recent versions can be called children's social participation which came to existence in recent decades following children rights convention. this fact can be brought into account ...

This paper deals with the design opportunities of Static Random Access Memory (SRAM) for lower power Consumption and propagation delay .Here we have analyzed both read margin for read ability and write margin for SRAM write ability. Static Noise Margin affects both read margin and write margin. We have analyzed the Static Noise Margin using traditional butterfly method which requires the rotati...

The African Program for Onchocerciasis Control (APOC) was launched in 1995 with the main goal being to boost the fight against onchocerciasis in Africa. In 2011, over 80 million people benefited from this intervention thanks to the contribution of 268.718 Community-Directed Distributors (CDD). These significant results obscure the role of women CDD in this fight. Indeed, the insufficient involv...

The midline diastema is a space (or gap) between the maxillary central incisors . The space can be a normal growth characteristic during the primary and mixed dentition and generally is closed by the time the maxillary canines erupt. Researchers and clinicians now believe that multiple factors may contribute to a midline space including abnormal frenum, midline bony clefts ,oral habits, soft ti...
