... block of the table summarizes the per- formance of the systems with ILP. We were first con- cerned with how well ILP works for the mention- pair model, compared with the normally used algo- rithm ... par- tial entity with a unique constant. Specifically, m j represents the jth mention (e.g., m 6 for the pronoun “he”). e i j represents the partial entity i before the jth mention. For example, e 1 ... male person and cannot co-refer with “she”. The entity-mention model based on Eq. (2) per- forms coreference resolution at an entity-level. For simplicity, the framework considered for the entity- mention...

Implemented algorithm for forward ... algorithm: One for training and the other for development (65% and 35% respectively). We train the learners with the training set and we evaluate the performance to pick the best feature with the ... dimensionality and find the best set of features for maximizing the PPV for Emotional class and NPV for Non- Emotional class. We applied the Wrapper Approach with Forward Selection as described in section...

It is necessary to examine this performance before we can investigate the bit error rate (BER). Without packet detection, the communica- tions system will fail. For our system ... the information used in the SMI. Once the pre-filter is performing well enough for synchroniza- tion to detect packets, the R 2 measurement can be taken, and the SMI pre-filter can be replaced with...

... [14, 23, 24]. Upper bounds Before giving upper bounds on the sizes of DNA codes with constant GC-content, we note some simple special cases: Proposition 1 For n>0 ,with0 ≤ d ≤ n and 0 ≤ w ≤ n, A GC 4 (n, ... upper-bounding A GC 4 (n, d, 0) = A 2 (n, d) with the Singleton bound, 2 n−d+1 (see e.g. [3]). Tighter upper bounds for A 2 (n, d) are known for many n and d — see for example [15]. Theorem 4 Suppose ... choices for the nucleotide in each position j ≤ m; for the m − w +2i positions j ≤ m for which x j and x 2m−j+1 both belong to {C, G} or both belong to {A, T }, the nucleotide at x 2m−j+1 is forced...
