Welcome to Cognitive Computing and Brain Informatics

The Group activity is centred around brain research, mainly brain computer interfacing (BCI) including EEG hyperscanning, and body sensor networking (BCI) for body and brain abnormality identification. Recently our main interest has been on seizure identification and stimulation of brain epileptogenic networks. This is through developing new adaptive and cooperative signal processing, model and data driven AI, and single- or multi-channel, multi-dimensional, and multimodal biomedical signal decomposition.

Our Focus

  • Human-centred AI for Cognitive Computing and Brain Informatics
  • Brain research (looking at functional, personal, behavioural, psychological and physiological disorders)
  • Brain functional data and signal (EEG, MEG, fMRI, joint EEG-fMRI) processing, understanding, and machine learning (seizure, dementia, autism, mental fatigue, sleep, pain, depression)
  • Brain-computer interfacing (BCI), brain EEG hyperscanning, mental and physical rehabilitation, and rehabilitative assessment
  • Analysis, processing, and learning of human related data
  • Multimodal data analysis and learning (EEG-fMRI, audio-video, medical data)
  • Body sensor networking

Signal processing, machine learning, and sensor networks are the major tools in biomedical data (signal, image, and patient peripheral information) understanding, recognition, and classification. In CCBI the major research focus is on developing ground breaking approaches to Human-centred AI, Brain research (looking at functional, personal, behavioural, psychological and physiological disorders), brain functional data and signal (EEG, MEG, fMRI, joint EEG-fMRI) processing, understanding, and machine learning (brain responses to various stimuli, seizure, dementia, autism, mental fatigue, sleep, pain, depression, mild cognitive impairment – MCI and Alzheimer,) brain-computer interfacing (BCI), brain EEG hyperscanning, mental and physical rehabilitation, and rehabilitative assessment, analysis, processing, and learning of human related data, multimodal data analysis and learning (EEG-fMRI, audio-video, medical data), and body sensor networking.

Core services we offer include:

  • Developing tools and algorithms for identification, classification, and scoring of generative and degenerative brain states, diseases and abnormalities.
  • Assisting with multi-modal real-time medical data analysis for monitoring, diagnosis, prediction of alarming states, and decision making.
  • Developing tools for Brain-computer interfacing particularly for rehabilitation.
  • Developing model-driven (for data fusion), data driven (for deep learning), and diffusion techniques (for cooperative learning) for AI and machine learning.
  • Speech processing for source separation, human identification, speech recognition, and speaker identification.
  • Medical image enhancement, fusion, anomaly detection, and diagnosis.
  • Advanced signal processing including processing of biomedical signals, speech, music, and medical images.

Sensor based gait recognition

New wearable sensors can circumvent the limitations of video-based gait recognition often used for rehabilitative assessment.

Body sensoring network

The information from wearable sensors can reveal physical, behavioural, and mental abnormalities and be integrated within an IoT system.

Intracranial brain stimulation

By processing the information from multichannel electrocorticogram mat the seizure networks in deep brain can be identified and localised.

Localization of brain event potentials for audio stimulation

Many human mental states and abnormalities can be identified by evaluating the brain responses to audio, visual, and haptic stimulations as the basis for brain-computer interfacing.
