A diagnostic platform powered by generative adversarial networks,
using active reinforcement learning to speed up training
and minimize the knowledge transfer effort
of human doctors.
We are currently active
in ophthalmology, cardio
and respiratory.
PROBLEM
01
NCDs
Non-communicable diseases
(NCDs) are the leading cause of death and disability worldwide (60%).
Among NCDs, cardiovascular, ocular and respiratory diseases account for 60% of deaths and 53% of total healthcare expenditures.
02
AI
Fully supervised
diagnostic AI suffers
from several limitations,
such as the need to train
on huge amounts
of labeled data and
its difficulties in managing inputs that are noisy, incomplete
or simply different
from the original dataset.
03
BARRIER
In a situation of shrinking budgets where 97% of resources are spent on acute treatment and not prevention, the adoption of telehealth technologies is hindered by a cost barrier, both in EU and in LDCs. AI can address this problem by supporting Medical Doctors in early detection of disease.

SOLUTION
A semi-supervised learning AI platform
able to learn from small labelled datasets
augmenting their dimension,
and predicting possible variations or
noise that could be met in the future,
to make the diagnosis robust in real-world settings.
Ophthalmology
The software we have clinically tested is capable of
segment OCT retinal scans to highlight diagnostic signs
and retinal layers for Diabetic Macular Edema.
The software is currently under CE-mark* ispection
and will revolutionize ordinary clinical practice.
Further development will involve other ocular diseases.
Respiratory
The software we are clinically testing is trying to estimate the probability of the presence of asthma and Chronic obstructive pulmonary disease.
Detection is performed by analysing the sound made
by a user blowing into the smartphone's mic.
Arrhythmias & Vascular
We developed a software able to estimate the probability of the presence of several heart conditions such as atrial fibrillation,
atrial flutter, other arrhythmias, hypertension, and abnormal heart rate variability.
Detection is performed by analyzing the PPG trace created
by video-selfie of the user staring at the smartphone camera.
Active Learning
Our platform is capable of selecting, from a clinical dataset, only the most informative samples, in order to present them to human doctors in an iterative fashion and get their feedback.
This way, the knowledge transfer effort of the doctors is minimized, and AI training can go faster, saving up to 90% of time and costs.
* Ophthal is under ispection to become a CE-Mark medical device according to the European regulation (UE) 2017/745
HOW IT WORKS
The Active Reinforcement Learning platform detects the most informative samples of a clinical dataset and submits them to Medical Doctors for labelling.
Then, the GANs platform propagates labels from small, manually labelled, image datasets to all the unlabelled ones, so that the diagnostic AI can be trained to identify conditions without
the need for costly and time-consuming human labelling (semi-supervised learning).
