Eye tracking has many applications from driver safety to improved accessibility for people with disabilities. There exist expensive and bulky hardware solutions for eye tracking but this project aims to bring robust and accurate eye tracking to everyone. Recent research and the pervasiveness of handheld devices with powerful cameras have now made it easy to have high quality eye tracking right in our pockets!.

The aim of this project is to allow researchers and developers all over the world to use our open-sourced eye tracker (with additional features) in new and varied use cases. From simple systems where the phone can be mounted on a stand in a vehicle to track multiple parameters of the driver: drowsiness, gaze, attentiveness to more complex applications like emotion analysis and even lie detection, the sky's the limit.

The functioning of complex systems (i.e. the brain, and many others) depends on the interaction between different units; crucially, the resulting dynamics is different from the sum of the dynamics of the parts. In order to deepen our understanding of these systems, we need to make sense of these interdependencies. Several tools and frameworks have been developed to look at different statistical dependencies among multivariate datasets. Among these, information theory offers a powerful and versatile framework; notably, it allows detecting high-order interactions that determine the joint informational role of a group of variables.

The goal of this project is to collect and refine existing metrics of high-order interactions currently implemented in Matlab or Java, and integrate them in a unified python-based toolbox. The main deliverable of the project is a toolbox, whose inputs are the measurements of different variables plus some parameters, and whose outputs are the measures of higher-order interdependencies. Ideally, the toolbox will interface with visualisation & processing platforms of neuroimaging data, such as MNE, fMRIPrep and can become a docker container too.

Unlike traditional inverse identification tools that rely on gradient and gradient-free methods, simulation-based inference has been established as the powerful alternative approach that yields twofold improvement over such methods. Firstly, it does not only result in a single set of optimal parameters, rather simulation-based inference acts as if the actual statistical inference is performed and provides an estimate of the full posterior distribution over parameters. Secondly, it exploits prior system knowledge sparsely, using only the most important features to identify mechanistic models which are consistent with the measured data.

The aim of the project is to support the simulation-based inference in the brian2modelfitting toolbox by linking it to the sbi, PyTorch powered library for simulation-based inference, development of which is coordinated at the Macke lab.

BIDS is a standard for neuroimaging datasets that helps with data sharing and reusability; as a result it has been widely adopted by the community. Although developed for MRI originally, it has gained popularity within the EEG and MEG realms. Converting raw data to the BIDS standard is not difficult but requires a lot of time if done by hand. Currently, software like mne-bids and Biscuit are available to assist and facilitate this conversion but there is still no automated way to produce a valid BIDS dataset for the EEG and MEG use-cases. Mostly what is missing is metadata.

The objective of this project is to implement a python package that infers the missing information from files accompanying the EEG and MEG files and/or a single bids-conversion example provided by the user. The idea of having human-readable configuration files will also be explored since this would help the sharing of common conversion parameters within similar communities. If successfully implemented, batch conversion of BIDS datasets in the EEG and MEG cases would be realized.

Understanding the inner wiring of the human brain is one of the most long-pursued goals of neuroscientists. In this journey, diffusion MRI (dMRI) and tractography algorithms offer the essential possibility of reconstructing the white matter bundles that interconnect brain regions. Building on this, it is of high interest to obtain tractography bundle atlases that describe the average connectome in different populations. Constructing these atlases, however, requires specific technical expertise and cannot be done in a simple way by using currently available neuroimaging software.

This project aims to fill this gap by integrating a tractography bundle atlas creation workflow into DIPY, a reference library for dMRI processing in python. The developed solution offers scientists a quick and easy way of obtaining population-specific tractography atlases in an automated fashion. The algorithm takes segmented bundles as input and relies on streamline based registration to align the bundles and construct an atlas. The whole atlas creation process is controlled by the user via a command line interface. Obtained atlases can be exported and used for visualization or further analyses.

The Interplanetary File System protocol is an emerging web standard that offers a unified open-source service for peer-to-peer sharing of datasets. Datasets stored on IPFS can be anonymized and permissioned, available as read-only by those with sufficient privileges, by linking the individual records to research participant or data curator DIDs, which can be revoked at any time by the owner of the dataset.

The goals of this project are to: i. build a pipeline for decentralized (IPFS) storage of BIDS-compliant neuroimaging data with support for version control and authentication through signatures associated with Decentralized IDs (DIDs) and ii. develop documentation, walk-throughs, and supplemental guidance to enable smooth integration with front-end and UX development.

Time-series analysis is a broad, interdisciplinary field, and features for analyzing time-series datasets are ever-increasing. This has led to creating an online Django platform, CompEngine-Features, for comparing new time-series analysis features with an existing set of over 7000 time-series analysis features in the hctsa package. However, the platform lacks: support for incorporating new features contributed by users, client-side rendering of web pages, network visualizations, line plots for Empirical1000 dataset, and async views in Django, all of which are crucial for the adoption of the platform and thus its ability to have a significant impact in driving progress in time-series analysis.

The aim of this project is to continue developing a Django online platform, CompEngine-Features, for comparing the performance of time-series analysis methods on real time-series data, including a wide range of neural dynamics.

ImageJ is extensively used in major areas of biological and material sciences. Previously developed active segmentation platform as a plugin for ImageJ incorporate Weka toolbox-based statistical machine learning algorithms as well as deep learning techniques for trainable image segmentation. The end goal of the active segmentation platform for ImageJ is to provide researchers an extensible toolbox enabling them to select custom filters and machine learning algorithms for their research. Under the existing implementation of the active segmentation platform, it only supports users with a limited way to load the ground truth for learning ( at the moment only as of the region on interest format (ROI)). Thus, this reduced the usability of the tool and it urges the users to convert the ground truth to the specific format which is designed to be used within the application.

The objective of this project is to incorporate several ground-truth formats as image-based in which each pixel uniquely belongs to a particular class, partial ground truth format in which instead of the whole image and several partial boxes in an image or stack are labeled.

AutSPACEs is a citizen science platform that aims to understand how sensory processing differences affect autistic people all around the world. It captures an autistic user's experiences with sensory processing challenges and generates a qualitative dataset. This data serves two main purposes:

  1. Contribute to making the world more inclusive of autistic people by urging policy-makers to make changes based on evidence and recommendations from a large number of lived experiences.

  2. Educate non-autistic people on how they can be better allies for autistic individuals and destigmatize autism in our society.

This project aims to build and implement a working prototype of the website in collaboration with the autistic community. The potential approach to this project would be the following: i. solve issues from milestones 2 and 3 which aim to increase the accessibility of the website and make it into a minimum viable product, ii. test and review PRs to ensure that they meet their purpose, iii. make appropriate documentation for the code, iv. send the final working prototype to the autistic community for feedback and make additional issues based on it.

The Calabrese Lab 8-cell Leech Tutorial that is described by Hill et al 2001 has been a staple for teaching computational neuroscience at Emory University for many years, and it has also been used in various summer courses. This tutorial is not only a fully constructed 8-cell circuit that can generate heart rhythms, but also a great teaching tool thanks to the visual interface where a student can turn on synaptic connections or change maximal ionic conductances. However, the original tutorial has been developed using the now obsolete Genesis simulator. Unfortunately, running the Genesis simulator nowadays requires complicated software set up that prevents many non-technical students from accessing the tutorial. We had previously started porting the tutorial to a more modern format that can be executed through a web browser (see 8-cell Leech Heartbeat Network Model Tutorial), increasing the accessibility of this classic tutorial for teaching and research purposes.

The objectives of this project are to complete the port previously started and make the tutorial available. We selected the Neuron simulator language for running the model using NeuroML and Python as the description languages.

Neuroscientists have begun to publicly share more and more datasets, however there are still barriers to making these datasets easily reusable by the community. One of these barriers has been the accessibility of shared data; it takes extensive time and effort to understand different data formats and determine which datasets are best suited for the scientific questions being asked.

The goal of this project is to convert publicly available datasets to the standardized NeuroData Without Borders (NWB) format so that they can be better interpreted and reused by other researchers. The data will then be made available for interactive analysis and visualization through the NWB explorer on the Open Source Brain repository. By using a standardized data format, researchers can more quickly work with new data and develop analysis methods to apply to a wide variety of datasets. The ability to easily explore and visualize data will also allow researchers to quickly assess the contents of the data and if they can reuse it. Thus, the results of this project will contribute to an important resource for scientists.

To guide behaviour, it has been proposed that neurons eventually learn to predict future states of sensory inputs. The project mentors have worked in this direction to get metrics on these predictions about how accurate those predictions are if the neuron used synaptic learning rules. The main contribution of this project would be to publish highly optimised library codes that can serve as evaluation benchmarks for predictive accuracy. We also believe that neurons can generate efficient encodings on these predictions. Through this project, estimates of the predictive information would also be obtained by neural models.

Goals:

  • Benchmark existing codes and optimise for integration
  • Mutual Information Estimation between neural response and future stimulus
  • Estimation of predictive accuracy
  • Using Statistical Models

Time series data is ubiquitous in many applications. Examples include sensor readings from industrial processes, spectroscopy wavelength data from chemical samples, or bed-side monitor medical data from patients. Developing advanced time series analysis capabilities for researchers and practitioners is one of the major challenges of contemporary machine learning.

sktime is a new Python toolbox for machine learning with time series and, to the best of our knowledge, the first unified toolbox for time series. The goal of this project is to provide for time series what scikit-learn provides for tabular data. This involves extending scikit-learn to the different time series learning tasks, such as time series classification, clustering, forecasting and anomaly detection.
