Case-Based Reasoning (CBR) is one of machine learning algorithms for problem solving and learning that caught a lot of attention over the last few years. In general, CBR is composed of four main phases: retrieve the most similar case or cases, reuse the case to solve the problem, revise or adapt the proposed solution, and retain the learned cases before returning them to the case base for learn...
Many fixed-parameter tractable algorithms using a bounded search tree have been repeatedly improved, often by describing a larger number of branching rules involving an increasingly complex case analysis. We introduce a novel and general search strategy that branches on the forbidden subgraphs of a graph class relaxation. By using the class of P4-sparse graphs as the relaxed graph class, we obt...
A deletion 8p syndrome is a relatively uncommon congenital disease characterized by mental retardation associated with multiple malformation that make anesthetic management a challenge. Anesthetic management of a patient with deletion 8p syndrome may pose a serious problem mainly from difficult tracheal intubation, aspiration complication and cardiac malformation. We experienced a case of 10 ye...
Remembering To Forget: A Competence-Preserving Case Deletion Policy for Case-Based Reasoning Systems
The utility problem occurs when the cost associated with searching for relevant knowledge outweighs the benefit of applying this knowledge. One common machine learning strategy for coping with this problem ensures that stored knowledge is genuinely useful, deleting any structures that do not contribute to performance in a positive sense, and essentially limiting the size of the knowledge-base. ...
Background & Objectives: Breast cancer is the most common cancer among women and the second most common cause of cancer death. Genetic factors play an important role in the development of breast cancer. Among these genetic factors, CHEk2 (checkpoint kinase 2) gene, as a tumor suppressor gene, plays a critical role in DNA repair. Germline mutations in CEHK2 result in the loss of this feature. On...
Digeorge syndrome is caused by microdeletion of a large region of chromosome 22q11.2 lead to the abnormal development of the third and fourth pharyngeal pouches. This syndrome is characterized by hypoparathyroidism, cellular immune deficiency secondary to thymic hypoplasia, congenital heart disease and dysmorphic facial features. In this case report, we describe a 4month old boy who presented w...
The meaning of an idiomatic expression cannot be transparently worked out from the meanings of its constituent words due to its figurative and unpredictable nature. Consequently, the syntactic composition and the structural paradigm of an idiomatic expression are supposed to be the same in every context. However, this is not the case in the institutionalized second language varieties of English...
Current research highlights the Hspb1 based screening of eight cat populations of the world to investigate the association of newly found locus within cat mammary tumors. Total 180 cats were screened on the basis of Hspb1 4 bp deletion locus (1514-1517del4) which was observed in six mammary tumor cases in Siamese cat breed. Case-control association study revealed the non-significance with P=0.2...
Among over 50 distinct mutations causing glucose-6-phosphate dehydrogenase (G6PD) deficiency, only two deletion mutations have so far been reported. Using nonradioisotopic single-strand conformation polymorphism analysis, we found two additional deletion mutations in two Japanese G6PD-deficient patients with nonspherocytic hemolytic anemia. Case no. 1 had a 3-nucleotide deletion in exon 6 predi...
The phenotype of 11q terminal deletion also known as Jacobsen syndrome is a clinically well known entity whose diagnosis in infancy and childhood is based on clinical examination, hematological and cytogenetic findings. Hematological features in Jacobsen syndrome are very similar to those reported in Paris-Trousseau syndrome (PTS) which is also associated with11q terminal deletion. Karyotype an...
