What is AI?
AI, or artificial intelligence, refers to the development of digital systems that can perform tasks that typically require human intelligence.
These tasks include learning, reasoning, problem-solving, perception, language understanding, and speech recognition.
At its core, AI leverages principles from computer science, mathematics, and cognitive psychology to replicate intelligent behaviour in machines.
AI utilises algorithms, data, and computational power to simulate intelligent behaviour, enabling machines to adapt, improve, and perform complex functions autonomously.
Several core scientific concepts underpin the development and functionality of AI. Work your way through the presentation below to hear about some of them:
This list of core scientific concepts in AI is subject to ongoing research and development. The field of AI is rapidly evolving, and new techniques, algorithms, and applications are continuously emerging.
As researchers and scientists make advancements in AI technology and explore novel use cases, the understanding and implementation of these concepts may evolve.

How are AI Systems Built?
AI systems are built through a process that involves several key steps.
Building AI systems is an iterative process, that involves ongoing refinement and improvement to keep up with evolving requirements and challenges.
Additionally, advancements in research and technology may prompt updates to models and algorithms.Key Applications of AI in the Healthcare Domain
Artificial Intelligence (AI) is revolutionising the healthcare domain, introducing transformative applications that can enhance diagnosis, treatment, and patient care. The synergy between advanced algorithms, machine learning, and healthcare data has paved the way for innovative solutions with the potential to improve outcomes, increase efficiency, and streamline processes.
Key applications of AI in the healthcare sector include:
Diagnostic imagery: AI excels in interpreting medical imaging data, such as X-rays, MRIs, and CT scans. Deep learning algorithms can detect patterns and abnormalities, aiding radiologists in accurate and swift diagnoses. This not only speeds up the diagnostic process but also enhances precision when identifying subtle anomalies.
Disease prediction & prevention: Predictive analytics powered by AI enables healthcare providers to forecast disease risks and identify individuals who may be predisposed to certain conditions. By analysing patient data and lifestyle factors, AI models can assist in implementing preventive measures and personalised interventions to mitigate potential health risks.
Drug discovery & development: AI can accelerate the drug discovery process by analysing vast datasets to identify potential drug candidates and predict their efficacy. Machine learning algorithms can analyse molecular structures, predict drug interactions, and optimise formulations, significantly reducing the time and cost associated with bringing new drugs to market.
Personalised medicine: AI enables the development of personalised treatment plans by analysing patient-specific data, including genetic information, medical history, and lifestyle factors. This approach allows healthcare providers to tailor interventions and medications to individual patient needs, improving treatment effectiveness and minimising adverse effects.
Chatbots: Chatbots and virtual health assistants powered by AI are used to enhance patient engagement and provide on-demand healthcare information. These tools can offer guidance on symptoms, medication reminders, and lifestyle recommendations. Proponents of virtual health assistants claim that they can improve patient adherence to treatment plans and foster better communication between patients and healthcare providers. However, this is disputed by those who are concerned about what may be lost through a decrease in human-to-human interactions.
Natural language processing and health records: The use of NLP algorithms to extract valuable insights from unstructured clinical notes and electronic health records facilitates efficient data management, enables faster information retrieval, and supports clinical decision-making. NLP also plays a crucial role in automating administrative tasks, allowing healthcare professionals to focus more on patient care.
Robotic surgery assistance: AI-powered robotic systems assist surgeons in performing complex procedures with precision and minimal invasiveness. These robotic platforms enhance surgical outcomes, reduce recovery times, and contribute to advancements in minimally invasive surgery techniques.
Alexei Grinbaum - the Benefits of AI
Alexei Grinbaum shares his thoughts on the benefits of AI.
Benefits of AI
Alexei Grinbaum – French Alternative Energies and Atomic Energy Commission (CEA)
AI in healthcare can bring two kinds of benefits. One for the patients, AI does non-human calculation. It can probably, through computation, discover things that we haven't discovered humanly, meaning new drugs, new treatments. And that is happening already. We are discovering new molecules that we had never thought about humanly. So that's for the patients.
Alexei Grinbaum - Reasons to be Cautious about the Use of AI
Alexei Grinbaum shares his thoughts on reasons to be cautious about AI.
Reasons to be cautious about the use of AI
Like with all artificial intelligence systems, there should be limits, filters, and controls. We shouldn't just let it go uncontrolled completely. So unchecked completely. First, of course, there is the classic question of data, personal data, sensitive data. This is about health, our data. Some of it is genetic. Some of it lets us identify people. How do we treat that data? So, that is a very classic question. But beyond that, there are very interesting questions about human autonomy. AI systems, will they overtake the doctors? Will they still leave a place for human contact, human warmth?
If we seek advice from an AI system, does it mean that somehow the medical profession is changing completely? So, these kinds of questions are important. Again, they're not exactly specific to the medical sphere. They also exist, for example, for AI assistance. But in the medical sphere, there are interesting questions that are a little bit more specific. Some would say, cybersecurity, you know, it's everywhere. We have all heard about robustness and cybersecurity. But in the medical sphere, if you have a device that is interacting with your body, and if somebody can hack it, well then of course, it's a direct threat to our well-being, to our health. So, the questions of cybersecurity are also very touchy, I would say, in the medical sphere.
And then beyond that, we have classic big questions about organisations. Will the whole sphere of medical care with the hospitals, you know, the emergency rooms and all of these things, how will that evolve? Should it be managed not by humans, but by robots or AI systems? Will they respond faster? How will that change the way we build our social institutions? And that's another dimension of AI in health care.
So, there are definitely benefits at each of these levels. But there are also risks, or I would say, reasons to be cautious, reasons not to go too fast with the deployment of AI systems, because the human profession doesn't change in 10 days, right? We need time to evolve. We need time to learn new skills.
Key Applications of AI In the Healthcare Domain Cont.
What are some of the key benefits of the use of AI applications in healthcare?
Click on the hotspots in the image below to see some of the benefits that we identified.
As AI continues to evolve, its applications in healthcare hold immense promise for improving the quality of care, optimising resource utilization, and potentially shaping a more patient-centered and efficient healthcare ecosystem. However, careful implementation and ongoing scrutiny is vital to ensure the responsible and beneficial use of AI in healthcare.
AI and the Protection of Health Data
As healthcare organizations strive to harness the benefits of AI while safeguarding patient data, a delicate balance must be maintained.
Stringent security protocols, transparent data governance, and ethical AI development practices are crucial for upholding the confidentiality and integrity of healthcare data in the era of AI-driven advancements.
Policymakers, healthcare providers, and technology developers must work collaboratively to establish robust frameworks, regulations, and ethical guidelines to ensure the responsible and secure use of health data in AI applications.
Antonija Mijatovic - Challenges for Data Privacy and Security
Antonija Mijatovic shares her thoughts on challenges for data privacy and security.
Challenges for data privacy and security
When it comes to data security and privacy, the major issues are data breaches. Because many applications in AI involve health data, and health data is sensitive and confidential by nature.
So, data breaches can lead to privacy violations, identity theft, even health risks. And they result in financial losses for healthcare organizations. Because healthcare is the top industry targeted by ransomware. Ransomware is a common cyber-attack. But aside of ransomware, data breaches can occur through hacking, phishing, and even if a device storing health information is lost or stolen. And data breaches can also happen unintentionally. For example, if patient data is emailed to the wrong recipient or posted online. And these incidents happen very often.
For example, in the United States alone, only in the last year there have been more than 500 cases of cyber-attacks. So, this is why it is important to address. Researchers need to take multiple measures to ensure data security and privacy. And these include cyber security measures, such as strong passwords, restricted access, two-factor authentication, and even encryption of very sensitive data. In addition, researchers should create backups of very important folders. And also, because 90% of cyber-attacks were allowed due to human error, researchers who work with sensitive data should receive proper training in the subject.
