Deep Autoencoders for Dimensionality Reduction of High-Content Screening Data

چکیده

High-content screening uses large collections of unlabeled cell image data to reason about genetics or cell biology. Two important tasks are to identify those cells which bear interesting phenotypes, and to identify sub-populations enriched for these phenotypes. This exploratory data analysis usually involves dimensionality reduction followed by clustering, in the hope that clusters represent a phenotype. We propose the use of stacked de-noising auto-encoders to perform dimensionality reduction for high-content screening. We demonstrate the superior performance of our approach over PCA, Local Linear Embedding, Kernel PCA and Isomap.

Sparse Autoencoders in Sentiment Analysis

This paper examines the utilization of sparse autoencoders in the task of sentiment analysis. The autoencoders can be used for pre-training a deep neural network, discovering new features or for dimensionality reduction. In this paper, sparse autoencoders were used for parameters initialization in deep neural network. Experiments showed that the accuracy of text classification to a particular s...

Autoencoding topology

The problem of learning a manifold structure on a dataset is framed in terms of a generative model, to which we use ideas behind autoencoders (namely adversarial/Wasserstein autoencoders) to fit deep neural networks. From a machine learning perspective, the resulting structure, an atlas of a manifold, may be viewed as a combination of dimensionality reduction and “fuzzy” clustering.

Image Tranformation Using Variational Autoencoders

The way data are stored in a computer is definitively not the most intelligible approach that one can think about even though it makes computation and communication very convenient. This issue is essentially equivalent to dimensionality reduction problem under the assumption that the data can be embedded into a low-dimensional smooth manifold (Olah [2014]). We have seen couple of examples in th...

Evaluating deep variational autoencoders trained on pan-cancer gene expression

Cancer is a heterogeneous disease with diverse molecular etiologies and outcomes. The Cancer Genome Atlas (TCGA) has released a large compendium of over 10,000 tumors with RNA-seq gene expression measurements. Gene expression captures the diverse molecular profiles of tumors and can be interrogated to reveal differential pathway activations. Deep unsupervised models, including Variational Autoe...

Time-lagged autoencoders: Deep learning of slow collective variables for molecular kinetics

Inspired by the success of deep learning techniques in the physical and chemical sciences, we apply a modification of an autoencoder type deep neural network to the task of dimension reduction of molecular dynamics data. We can show that our time-lagged autoencoder reliably finds low-dimensional embeddings for highdimensional feature spaces which capture the slow dynamics of the underlying stoc...
