Study Notes
Policing and AI Applications
- AI-powered policing applications are discussed in relation to early intervention systems (EIS).
Machine Learning
- AUC (Area Under the Curve) in machine learning classification problems measures the model's ability to distinguish between classes.
Policing Applications
- The binary classification problem in this application is determining the likelihood of an individual committing a crime.
- The main goal of an early intervention system (EIS) is to predict and prevent future crime.
User-Centric Approach
- A user-centric approach focuses on the needs of marginalized communities to ensure digital safety.
- This ensures fairness and prevents bias in the development of digital platforms.
Data Privacy and De-identification
- De-identification involves removing or altering personal identifiable information from datasets.
- Irrevocably deleting personal information from datasets is a form of de-identification.
Regulatory Frameworks
- The General Data Protection Regulation (GDPR) is a key regulatory framework focused on data privacy in the era of big data.
Legal Information Accessibility
- Technology has significantly improved access to legal information for the general public.
UN Definitions
- Katrina Denver referenced the UN definition of human rights during the discussion.
Personalized Algorithms
- Personalized algorithms raise concerns about influencing user behavior.
Surveillance Capitalism
- Surveillance capitalism focuses on extracting data from individuals to create profit.
Web Server Personalization
- Web servers identify and personalize user experiences through cookies and browsing history data.
Modern Retail
- The main constraint for shoppers and store owners in the old world shopping experience was the lack of information and limited interactions.
Fraud Detection
- Soft fraud involves exaggeration or misrepresentation of information.
Privileged Learning in AI
- Privileged learning is an AI method that leverages additional information about data for better prediction.
Explainable AI
- Explainable AI is used in Shift's fraud detection algorithm to transparently explain the reasons behind decisions.
Insurance Industry Challenges
- The main challenge faced by the insurance industry due to digitization is the need to adapt to changing customer expectations and new risks.
AI Overfitting
- Overfitting occurs when a model performs well on training data but does not generalize to unseen data.
Big Data Characteristics
- The three V’s of big data are Volume, Variety, and Velocity.
AI and Big Data
- The primary advantage of using big data in the context of AI is the ability to train models and make accurate predictions.
Turing Test
- The Turing test assesses a machine's ability to exhibit intelligent behavior equivalent to or indistinguishable from a human.
Generalization in AI
- Generalizability in AI refers to a model’s ability to perform well on tasks that have never been encountered during training.
General AI
- General AI refers to an AI system with human-level intelligence capable of performing any task a human can.
AI Goals
- The main goal of artificial intelligence (AI) is to create intelligent machines that can solve problems and improve decision-making.
Big Data Value
- The main value of big data lies in its potential to extract insights, patterns, and knowledge.
Non-standard Data
- Non-standard data is characterized by being collected in a non-conventional or non-structured way, like unstructured text or sensor data.
Big Data vs. Classical Data Science
- The key difference between big data and classical data science is the focus on data volume and scale in big data.
Big Data vs. Alternative Data
- The distinguishing line between big data and alternative data is the source of the data. Alternative data refers to non-traditional data sources beyond traditional business data.
Big Data Characteristics Defined
- Doug Laney’s three V’s of big data are Volume, Velocity, and Variety.
Skills Needed for Big Data
- Data science skills are essential for individuals working with AI technologies in the age of big data.
ShotSpotter
- ShotSpotter uses acoustic sensors to detect shots fired.
- Ralph Clark changed the ShotSpotter business model to focus on proactive crime prevention by providing real-time information to police.
Data Scale
- A zettabyte has 21 zeros.
Distributed Data Access
- Cloud computing allows access and interaction with large amounts of data across various locations globally.
Deep Fakes
- Generative adversarial network (GAN) models are primarily responsible for generating deep fakes.
AI Image and Video Generation
- Generative AI creates hyper-realistic images and videos of non-existent entities.
AI Training
- The "test" in AI training is used to evaluate the model’s performance on unseen data.
Big Data Challenges
- The main challenge of working with big data is managing its sheer volume and complexity.
Energy Consumption in AI Models
- Factors contributing to energy consumption in large models include training on large datasets and model size.
Smaller AI Models
- Larger language models are adopting smaller, more efficient architectures to reduce energy consumption.
Transformer Models
- Transformer models have a core feature called attention that allows them to efficiently process sequences of information.
Word Embeddings
- Word embeddings like Word2Vec achieved a breakthrough by representing words in a continuous vector space, capturing semantic relationships.
Natural Language Processing Limitations
- Statistical models used in early natural language processing were limited by relying on explicit rules and lacked the ability to handle complex language structures.
AI Governance
- A governance model is suggested for implementing AI in public services to ensure fairness, accountability, and transparency.
