Important Definitions

Artificial intelligence covers a lot, so to find out how to keep it safe, the first thing is to understand what AI means. It's like taking the first step to figure out what AI is all about before we can make sure it stays secure.

Artificial Learning

Artificial intelligence is when a system can understand and use information, both clear and hidden, to do tasks that might be seen as smart if a person did them. It's like making a computer or machine act clever in a way that resembles how humans do things.

Supervised Learning

Supervised learning is when the computer learns from labeled examples to predict outcomes for new inputs.

Supervised learning offers diverse algorithms for tasks like linear regression, logistic regression, decision trees, random forests, SVM, KNN, Naive Bayes, neural networks, and boosting methods.

The choice depends on the data and task, each algorithm tailored to specific applications, ensuring flexibility and accuracy in various scenarios.

Semi-supervised Learning

Semi-supervised learning uses partly labeled data, improving the model even with unlabeled data.

Semi-supervised learning algorithms, leveraging both labeled and unlabeled data, include Self-training, where the model labels its predictions; Co-training, employing multiple views of the data; and Multi-view learning, utilizing different perspectives.

These methods harness unlabeled data to enhance model accuracy and address real-world challenges with limited labeled samples.

Unsupervised Learning

Unsupervised learning deals with unlabeled data, finding patterns and groups within it.

Unsupervised learning algorithms, without labeled data, encompass K-Means clustering for grouping, hierarchical clustering for tree-like structures, DBSCAN for density-based clustering, and Principal Component Analysis (PCA) for dimensionality reduction.

These algorithms unveil hidden patterns and structures within data, facilitating insights and understanding without predefined labels.

Reinforcement Learning

Reinforcement learning involves agents learning actions to maximize rewards through experience gained by interacting with an environment and undergoing state transitions.

Reinforcement learning algorithms, like Q-Learning and Policy Gradient, help computer agents make good decisions by learning from experience.

It's like teaching them to figure out the best actions through trial and error, so they can maximize rewards in different situations.

Life Cycle for Machine Learning

The machine learning lifecycle involves data collection, data curation, model design, evaluation, deployment, and continuous improvement, ensuring effective learning and adaptation.

Phase	Description	Risks(CIA)	Example Attack
Data Acquisition	Obtaining data from various sources; risks during acquisition, transmission, and storage.	Integrity	Poisoning attack
Data Curation	Preparing data as required by ML system; risks during acquisition, transmission, and storage.	Integrity	Bias
Model Design	A machine learning system's design includes various parts like drawings, formulas, cost calculations, and ways to improve. In complex models, such as Convolutional Neural Networks (CNNs) or Recurrent Neural Networks (RNNs), each layer has its own set of these elements.	Generic Risks	Model Tampering
Software Build	Specifying, designing, and implementing software	Generic Risks	Code Injection
Training	Critical phase Establish baseline behavior	Confidentiality, Integrity, Availability	1. Poisoning Attacks 2. Zero Knowledge attack 3. Backdoor vulnerability
Testing	Validating model performance and testing code; risks involve adversarial testing and the need for comprehensive test coverage.	Availability	Denial of features
Deployment	Challenges in deployment, architecture choices, and hardware/software deployment	Confidentiality, Integrity, Availability	Backdoor Attacks
Upgrades	Treating upgrades cautiously and managing model parameter updates	Integrity, Availability	Parameter Manipulation Poisoning Attack

Conclusion

To sum it up, keeping artificial intelligence safe involves taking care at every step, from getting data to using the AI model. We need to make sure the data is good, the model is secure, and be watchful for potential problems. By staying alert and working together, we can create a trustworthy and secure future for artificial intelligence.
