Visualise your stats interactively
Create a view with dynamic and responsive widgets visualizing different stats, such as, distributions, scatters, correlations, and box plots.
Compare different data subsets
Comparing different subsets has never been easier. Simply define two or more filters and let Ada do the rest.
Import and export data sets
For a quick and flawless data integration, Ada provides the import adapters for 6 file formats and APIs. For post-processing, data can be exported into 3 file formats, or pulled directly through Ada's RESTful API.
Access the dictionary
The dictionary panel allows to change the way how fields are displayed on-the-fly. You can also investigate the field types inferred during the data set import.
Unleash the power of Spark-based ML
Any data sets residing in Ada can be "mined" for classification using, e.g., random forest and multilayer perceptron, or regression with, e.g., generalized linear regression and gradient boost regression tree.
Ada provides key infrastructure for secured integration, visualization, and analysis of heterogeneous clinical and experimental data generated during the NCER-PD project.
NCER-PD research project focuses on improving the diagnosis and stratification of Parkinson's disease (PD) by combining detailed clinical and molecular data of patients to develop novel disease biomarker signatures.
Ada allows users to conveniently explore and filter data sets and produce configurable and personalized "views" containing charts and widgets for various statistics.
The platform currently manages anonymized data sets associated with clinical research pulled from NCER-PD REDCap system, biosample-related information provided by IBBL, and kinetic data from mPower mobile application and eGait shoe sensors. Also, Ada hosts DeNoPa study clinical data (three visits), which will be used for cross-study comparison.
Ada's main features include a convenient web UI for data set exploration and filtering, and configurable views with tables and charts showing basic statistics, such as, distributions, scatters, correlations, and box plots. To define data set’s metadata Ada provides an editable dictionary, and a category (I2B2) tree with drag-and-drop manipulation. Furthermore, Ada facilitates robust access control through LDAP authentication, and in-house user management with fine-grained permissions.
For post-processing filtered data can be exported into CSV, JSON, or tranSMART format. The data set import adapters currently support two file formats: plain CSV and tranSMART data and mapping files, and three secured RestFul APIs: REDCap, Synapse (Sage Bionetworks Data Provenance System), and eGait. Any data sets provided from these sources can be added to (or removed from) Ada on-the-fly without much effort. The data set imports can be also scheduled for periodic execution. As such, Ada has potential to be used beyond NCER-PD project for other translational medicine endeavours.
For more advanced analysis, well-grounded machine learning and statistical approaches were integrated to Ada using Spark ML library.
