We hypothesize that as the size of the image patch spanned by each basis vector increases, the resulting dictionary should encompass a broader range of spatial scales, including more features that better discriminate between object classes. Previous efforts to measure the effects of patch size on image classification performance were confounded by the difficulty of maintaining a given level of overcompleteness as the patch size is increased. Here, we employ a type of deconvolutional network in which overcompleteness is independent of patch size. Based on image classification results on the CIFAR10 database, we find that optimizing our deconvolutional network for sparse reconstruction leads to improved classification performance as a function of the number of training epochs. Different from previous reports, we find that enforcing a certain degree of sparsity improves classification performance. We also find that classification performance improves as both the number of learned features (dictionary size) and the size of the image patch spanned by each feature (patch size) are increased, ultimately the best published results for sparse autoencoders","PeriodicalId":415083,"journal":{"name":"International Conference on Bio-inspired Information and Communications Technologies","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115252567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In vitro motility assays commonly used in biophysical studies on protein-motors now fulfill the demand described above. Using the in vitro motility assays, we report collective motion and vortex emergence of microtubules (MTs) driven by some subspecies of axonemal dyneins and find that under some experimental conditions, the collective motion of MTs can display nematic order, millimeter-scale meandering streams or millimeter-scale vortices. To explore the conditions causing such phase-shifts, we examine the effects of mechanical properties of dyneins on the pattern formation.","PeriodicalId":415083,"journal":{"name":"International Conference on Bio-inspired Information and Communications Technologies","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128278732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microtubule, a self-organization system assembles itself into functional units by attaching to cellular structures. Modeling microtubule self-organization is of interest as microtubule forms a network of protein filaments that is critical to many processes in eukaryotic cells. In this paper, we developed a modeling algorithm starting from alpha and beta tubulins as basic building block in the self-organization of microtubule. The developed algorithm and the necessary steps are described in detail. The preliminary results obtained from the model demonstrate that a stable self-organization conformation is possible for a microtubule.","PeriodicalId":415083,"journal":{"name":"International Conference on Bio-inspired Information and Communications Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130217303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent experimental advances have led to high-throughput methods of capturing information about chromatin conformation on genome-wide scales. New models are needed to quantitatively interpret this data at a global scale. Here we introduce the use of tools from topological data analysis to study chromatin conformation. We use persistent homology to identify and characterize conserved loops and voids in contact map data and identify scales of interaction. We demonstrate the utility of the approach on simulated data and then look data from both a bacterial genome and a human cell line.

We discuss the sensitivity of the standard filtration and show cases where reticulate evolution can fail to be detected. We introduce an extension of the standard framework and define the median complex as a construction to recover signal of the frequency and scale of reticulate evolution by inferring and imputing putative ancestral states. Finally, we apply our methods to two datasets from phylogenetics.
