Abstract Autism spectrum disorder (ASD) is a highly complex neurodevelopmental characterized by deficits in sociability and repetitive behaviour, however there great heterogeneity within other comorbidities that accompany ASD. Recently, gut microbiome has been pointed out as plausible contributing factor for ASD development individuals diagnosed with often suffer from intestinal problems show differentiated microbial composition. Nevertheless, studies rarely agree on the specific bacterial...

Abstract Background MicroRNAs (miRNAs) are noncoding RNA molecules heavily involved in human tumors, which few of them circulating the body. Finding a tumor-associated signature miRNA, that is, minimum miRNA entities to be measured for discriminating both different types cancer and normal tissues, is utmost importance. Feature selection techniques applied machine learning can help however they often provide naive or biased results. Results An ensemble feature strategy signatures proposed....
