"The human gut is home to a diverse community of microbes. Variations in the makeup of this community between individuals have been linked to diseases such as inflammatory bowel disease, diabetes, and cancer. Efforts to understand these differences have revealed three community types, or enterotypes, in humans, each representing the dominance of a single microbe. But because microbes co-mingle with many partners, studying the gut microbiome solely in terms of enterotypes misses on the highly nuanced nature of microbial interactions. Researchers recently addressed that shortcoming using a machine learning technique called latent Dirichlet allocation, or LDA. Their goal was to determine whether and how recurring microbial partnerships, or assemblages, are linked to the three enterotypes. Using gut metagenomic data gathered from 861 healthy adults across 12 countries LDA revealed three assemblages corresponding to each enterotype as well as a fourth wild-card assemblage that could be found in any gut..."

"Metagenomics is a powerful technique for studying complex microbial communities. The key computational step in this method is clustering genomic sequences from mixed samples into potential microbial genomes, but accurately classifying sequences from complex metagenomes remains challenging. Some tools depend on k-mer frequency and coverage, but such methods struggle to distinguish between similar genomes. Methods that address the similar genomes problem, like ones that rely on single-copy marker genes, in turn struggle with complex datasets. The newly developed MetaDecoder balances these challenges by using both types of methods broken into two steps. First, MetaDecoder simplifies the dataset by generating preliminary groups of sequences with the Dirichlet Process Gaussian Mixture Model (DPGMM). Then, these preliminary clusters are clustered further with a k-mer frequency probabilistic model and a modified Gaussian Mixture Model of single-copy marker gene coverage..."

The course focuses on the problem of supervised learning within the framework of Statistical Learning Theory. It starts with a review of classical statistical techniques, including Regularization Theory in RKHS for multivariate function approximation from sparse data. Next, VC theory is discussed in detail and used to justify classification and regression techniques such as Regularization Networks and Support Vector Machines. Selected topics such as boosting, feature selection and multiclass classification will complete the theory part of the course. During the course we will examine applications of several learning techniques in areas such as computer vision, computer graphics, database search and time-series analysis and prediction. We will briefly discuss implications of learning theories for how the brain may learn from experience, focusing on the neurobiology of object recognition. We plan to emphasize hands-on applications and exercises, paralleling the rapidly increasing practical uses of the techniques described in the subject.

"Lignocellulose is a major component of the woody portion of plants. The polymers it houses, like xylan and cellulose, could be used as biofuels or in other plant-based materials. The breakdown of lignocellulose requires specialized carbohydrate-active enzymes (CAZymes), but targeted discovery of novel CAZymes is difficult due, in part, to their structural diversity. In a recent paper, researchers have proposed a new method to speed up this process. They combined phenotype-based selective pressure with functional profiling to screen unknown enzymes. Feeding cattle a forage-based diet applies selective pressure on their rumen microbiota for microbes with specialized fiber-degrading enzymes. Three glycoside hydrolase families had increased abundance in feed-efficient cattle compared to their inefficient counterparts on this diet. Screening some members of those families against a database of uncharacterized enzymes led to the identification of putative xylanases and endoglucanases..."

"Biopesticides are widely available insect control applications derived from plant, animal, or bacterial proteins. They do not leave harmful residues and are more target-specific than chemical pesticides, but long-term use has led to resistance. Insecticidal protein genes (IPGs) are frequently found encoded in the genomes of arthropod pathogens, especially in the large plasmids found in soil bacteria. However, there are often several similar IPGs found on the same plasmid, which fragments their assembly. Further complicating the search, existing prediction tools analyze one contig at a time, and many IPGs are spread across multiple contigs, but the structure of the genome assembly graph can be used to combine multiple contigs. A new tool, ORFograph, uses this ‘graph-aware’ technique to predict IPGs. Benchmarking ORFograph on genomic and metagenomic datasets yielded both known IPGs that were “hidden” in assembly graphs and potential novel IPGs that had evaded existing tools..."
