Artificial Intelligence (AI) is a discipline that enables machines to mimic intelligent human behavior.

Artificial General Intelligence (AGI) refers to the ability of a machine to perform any task a human being is capable of.

Current capabilities can be positioned along what is called the “jagged technological frontier”.

AI and Generative AI are changing the way people learn, work and live – there are opportunities but also challenges.

These capabilities of AI to produce human-like work have improved rapidly, especially since the release of Generative AI, a category of Machine Learning technology that is able to produce new multimedia content based on existing data patterns.

AI Basics

Models

Programs that can find patterns or make decisions from a previously unseen dataset. They are built on foundations of algorithms and large datasets that enable them to analyze patterns and solve complex problems

Data

Feedstock of AI. Feed an AI model text-image pairs and the AI model develops the ability to recognize or generate images. Feed a GenAI model music and it will compose music. “You are what you eat” perfectly captures the importance of data as an AI building block.

Computing

Computational resources and processing power required to train, develop and run AI models. These resources include central processing units (CPUs), graphics processing units (GPUs) and specialized hardware like tensor processing units (TPUs).

Some definitions

Artificial intelligence

Artificial intelligence is a technical and scientific field devoted to the engineered system that generates outputs such as content, forecasts, recommendations or decisions for a given set of human-defined objectives. [ISO/IEC 22989:2022]

Machine Learning

A subset of AI that uses algorithms to learn insights and recognize patterns from data, applying it to make better decisions. ML can be supervised (i.e., using labeled datasets) or unsupervised (i.e., finding patterns within unlabeled datasets).

Deep Learning

Advanced subset of Machine Learning that leverages neural networks to learn from vast amounts of data.Neural networks enable systems to learn hidden patterns from data by themselves and build more efficient decision rules.
Popular applications of DL include computer vision and natural language processing (NLP).

Generative AI

A subset of artificial intelligence that uses generative models to produce text, images, videos, or other forms of data. These models learn the underlying patterns and structures of their training data and use them to produce new data based on the input, which often comes in the form of natural language prompts.

AI Capabilities

AI capabilities cover an expanding, but uneven, set of knowledge work that has been represented by the “jagged technological frontier”. This is a “virtual” line, moving through time as technology advances, and separating tasks “inside the frontier” from tasks “outside the frontier”.

The rationale is to distinguish what is within this moving frontier, i.e., tasks in which AI technologies can complement or even outperform human work, from what is outside the frontier, where the output produced by AI technologies can be inaccurate, less useful, or degrades human performance.

People who skillfully navigate this frontier gain large productivity benefits when working with AI technologies, while AI technologies can actually decrease performance when used outside the frontier.As the capabilities of AI are rapidly evolving and poorly understood, it can be hard for professionals to grasp exactly what the boundary of this frontier might be at a given point.

Generative AI

Two discoveries have made the history of Generative AI: the transformer and the related attention mechanism.

Generative AI tools are input-outputs machines. The input is given by the user and with the new Multimodal AI can be in different formats (text, image, video, audio, code).

The output is different depending on the specific tool, and can be text, image, video, audio, code as well.

Most LLMs have in them an element of randomness that allows them to return slightly different results each time they are asked the same question.

Moreover, their functioning can be set according to temperature which represents the accuracy in generating the new information, compared with the training/input data.

Prompting

Generative AI systems produce outputs based on prompt quality, and prompt engineering improves their ability to handle various queries effectively.

The elements of a good prompt:

Persona: ask the tool to take a role.

Objective: define what you want the AI to do.

Audience: specify who the output of the prompt is for.

Context: indicate what the tool needs to know.

Boundaries: set your own direction & limitation.

Tip: iterate and engage in a conversation, trying to spot pitfalls in your requests and crafting different prompts on the same task. In this way, you will critically evaluate the output of the LLM but you will also practice your metacognitive skills (learning how to think about something and evaluating your reflection processes).

AI Challenges

Artificial intelligence (AI) is revolutionizing various fields, enhancing innovation and efficiency. However, its rapid advancement also brings significant challenges that require careful consideration.

Algorithmic Bias

 

AI models may perpetuate existing biases found in their training data, impacting outcomes, and consequently, decisions informed by them.

Privacy & Data Security

 

Providing personal or sensitive data to AI systems is risky in terms of privacy, due to difficulties in tracing their use and transfer.

Opaque Decision Making

 

Known as the “Black Box” problem, AI often lacks transparency in how it processes inputs and produces outcomes.

Intellectual Property

 

AI use in academic research and content creation raises concerns about unintentional plagiarism.

Lack of Originality

 

Excessive use of AI may reduce creativity and novelty in solutions and ideas.

De-skilling

 

Over-reliance on AI may produce a de-skilling of human competencies; it can be detrimental toour ability to learn, critically analise and independently solve tasks.

Key issues in academia

Risks

 

  • Academic integrity: risk of plagiarism or counterfeit assessments, essays, and exams.
  • Over-monitoring: effectively limiting or preventing AI misuse by students can become very time-consuming and stressful for instructors.
  • Hallucinations:  AI outputs can be unreliable and provide plausible but incorrect information, due to the statistical recombination of input data.
  • Misuse of AI: AI may be used for purposes beyond its intended aim, leading to unethical or illegal applications.
Opportunities

 

  • Innovate teaching and evaluations: AI can foster the design of personalized activities and assessments, promoting a shift towards active learning and critical engagement with course materials.
  • Interactive Learning: AI tools can facilitate interactions, via simulations, debates, and real-time feedback, improving comprehension and engagement.
