“Understanding AI Jargon: Key Terms Explained”

August 30, 2023

Here’s a breakdown of some common terms and concepts, organized by topic:

General AI Concepts

  1. Artificial Intelligence (AI): The simulation of human intelligence in machines.
  2. Machine Learning (ML): A subset of AI that enables machines to learn from data.
  3. Deep Learning: A type of ML that uses neural networks with many layers.
  4. Natural Language Processing (NLP): A field focusing on the interaction between computers and human language.
  5. Reinforcement Learning: A type of ML where an agent learns to make decisions by receiving rewards or penalties.

Algorithms and Models

  1. Algorithm: A set of rules or steps that a computer follows to perform a task.
  2. Model: A mathematical representation of a real-world process based on data.
  3. Neural Network: A model inspired by the human brain, used in deep learning.
  4. Decision Tree: A flowchart-like model used for decision-making.
  5. Support Vector Machine (SVM): A classification algorithm that finds the hyperplane that best divides a dataset into classes.


  1. Dataset: A collection of data used to train or test a model.
  2. Training Data: The portion of the dataset used to train a model.
  3. Testing Data: The portion of the dataset used to evaluate a model.
  4. Feature: An individual measurable property of the data.
  5. Label: The output variable in supervised learning.

Evaluation Metrics

  1. Accuracy: The ratio of correctly predicted instances to the total instances.
  2. Precision: The ratio of true positives to the sum of true positives and false positives.
  3. Recall: The ratio of true positives to the sum of true positives and false negatives.
  4. F1 Score: A balanced measure of precision and recall.
  5. Confusion Matrix: A table used to evaluate the performance of a classification model.

Hardware and Software

  1. CPU (Central Processing Unit): The main processor of a computer, generally less specialized but more versatile than GPUs for AI tasks.
  2. GPU (Graphics Processing Unit): A specialized processor efficient for the matrix and vector operations commonly used in AI.
  3. TPU (Tensor Processing Unit): A specialized chip designed specifically for machine learning tasks.
  4. TensorFlow: An open-source ML library developed by Google.
  5. PyTorch: An open-source ML library developed by Facebook.

Ethics and Bias

  1. Ethical AI: The study of ensuring that AI systems operate in a manner that is ethical and just.
  2. Bias: Prejudice in favor of or against one thing, often in a way considered to be unfair.
  3. Explainability: The ability to explain the decisions made by AI systems.
  4. Transparency: The openness about the functioning and decision-making of AI systems.
  5. Data Privacy: Protecting the information used in and generated by AI systems.
