Title: Unsupervised Deep Learning: Applications in Metagenomics, Metabolomics and Drug Characterisation.
Abstract: (link for the full abstract with references)
Most of the existing Deep Learning methods rely on the assumption that all possible class labels sufficient to apply Supervised Learning are available. Although these types of learning algorithms can be generalized, their predictive power will be heavily constrained in the presence of partial information of a problem. For example, the classes that are available to a classifier are assumed to be ground truth, and their .correctness. is not generally questioned. In contrast to this approach, we propose a learning framework where the number of classes within a dataset do not need to be known a priori, and more specifically, the entire set of class labels are not required at the time of training. Instead, we propose to develop a method that will be able to infer the number of classes based only on the data and generate a more representative set of classes to train a robust classifier. Furthermore, we will also relax the assumption that these class labels are ground truth, and allow a degree of uncertainty in their correctness. An interesting solution for a subclass of these problems is Positive Unlabelled Learning .
Applying data analytics to microbial ecology has direct benefits to the design of vaccines and treatments to emerging pathogens, such as the Zika virus. In Metagenomic applications, very little may be known since we have only curated information pertaining to less than 2% of microbial diversity, and far less for novel variants of viruses. It is therefore not a realistic assumption that one can access all the true and underlying (organism) classes of any available data when analysing these organisms. Moreover, if we also consider the different and unknown number of effects that viral mutants can have on different hosts, and that these mutations could be linked to several environmental or geographical factors, we arrive at a complex, heterogeneous data set where labels are mostly unavailable, or any pre-existing labels available may be incorrect or not applicable to emerging viral strains. Even so, all these different types of data are essential to building a near-complete picture of the problem and understanding these pathogens at a deeper, more intimate level [2,3]. Statistical analysis of DNA sequence data has previously assisted us in identification of features that may further be used to discriminate species in a sample of multiple organisms using unsupervised learning methods [8-10]. Methods for increasing the resolution in realising the microbial population structure in a metagenomic sample is being worked on and coupling known data with unsupervised learning is found to be useful.
Repositioning of existing drugs as appropriate medication for previously not associated medical conditions can reduce the time, costs and risks of drug development by identifying new therapeutic effects. Investigating and understanding the interactions between drugs as well as how they work on our body is important in improving the effectiveness of clinical care. A method based on Positive Unlabelled Learning and Growing Self Organising Maps  is used on data available in DrugBank database. It was possible to infer 589 drug pairs that are likely to not interact with each other. Unsupervised Deep Learning also contributes in working with multielectrode array data .

Title: A protocol for finding missing proteins.
In the quest to uncover the entire human proteome, finding "missing proteins" remains the Holy Grail of scientists. In order to capture existing information, in addition to high-stringency MS data, we have launched the MissingProteinPedia (MPP; missingproteins.org), as an integrative biological database. While MPP incorporates automated data collection, novel tools for functional annotation and collated publications, there is an urgent need to identify a protocol for evaluating MPP data, to facilitate missing protein annotation jamborees. We will present how best to evaluate "extraordinary evidence" for missing proteins, with some exciting data confirming successful uncovering of some missing proteins.
