Study Notes

Machine Learning

Machine learning is a branch of AI that uses statistical methods to get computers to perform tasks without explicit instructions.
Example: Spam detection

Spam Detection

Machine learning systems use statistical methods to classify email as spam or not.
Email features used for classification:
- presence of words like lottery, inheritance, or typos
- familiarity of the email sender
The system assigns a probability to each email being spam using a statistical model.
This model is trained on a dataset of labelled emails (spam or not spam).

Supervised Learning

Supervised learning algorithms learn from data that is labeled with the correct answer.
They try to find a pattern in the data that predicts the correct answer for new data.
Example: predicting drug trafficking sentences given the quantity trafficked.

Legal Dispositionism and AI

Dispositionism: Attributing actions to internal reasons, motives, and intentions.
The law frequently assumes that people have control over their actions and are responsible for their choices.
AI raises challenges to dispositionism because AI systems are often seen as lacking agency or intent.

The Missing Person Problem

The law is ill-equipped for AI because it assumes human agents as the primary actors.
AI systems perform tasks that were previously only done by humans, raising questions about who is liable.
We need to identify new actors and responsibilities when AI systems are involved.

The AI and the Situation

Psychologists emphasize how external situations influence human actions, contradicting the dispositionist view.
The AI’s situation includes factors like the regulator, manufacturer, programmer, operator, and users.
We should not focus solely on the AI; its environment and context are also crucial.

DABUS Case Study

The Artificial Inventor Project argues that DABUS, an AI system, should be registered as a patent inventor.
DABUS is described as having the ability to perceive, think, and feel like a person.
However, the court decisions on DABUS have been mixed, with no jurisdiction recognizing it as an inventor so far.

Anthropomorphic Bias and the Android Fallacy

AI research has identified an "anthropomorphic bias" – attributing human-like qualities to AI systems.
Legal scholars have called this the "android fallacy," personifying mathematical computations.
We need to be wary of legal narratives that dispositionalize AI; AI systems are ultimately statistical computations.

AI as Statistical Computation

AI systems are not autonomous, but rather follow statistical algorithms and trained models.
We need to understand that AI systems are not "thinking" or "feeling" but rather are mathematical models that operate based on data.

Elon Musk and the Future of AI

The video mentions Elon Musk's concerns about the future of AI, particularly the development of artificial superintelligence.
It highlights ongoing debates and developments in the AI field.
