Term & DefinitionMeaning
AI
Artificial Intelligence
Computer systems able to perform tasks that usually require human intelligence.
AI/MLaaS
Artificial Intelligence/Machine Learning as a Service
The offering of AI and ML capabilities as part of cloud computing services.
AGI
Artificial General Intelligence
Highly autonomous systems that outperform humans at most economically valuable work.
ANN
Artificial Neural Networks
Computing systems inspired by the human brain's neural networks. They are a key component of Deep Learning (DL).
AutoML
Automated Machine Learning
The process of automating the end-to-end process of applying machine learning to real-world problems.
BERT
Bidirectional Encoder Representations from Transformers
An LLM method developed by Google and used in NLP.
CNN
Convolutional Neural Networks
A class of DNN, most commonly applied to analyzing visual imagery.
DL
Deep Learning
A subset of ML that structures algorithms in layers to create an artificial neural network that can learn and make intelligent decisions on its own.
DNN
Deep Neural Networks
A type of ANN with multiple layers between the input and output layers.
GAN
Generative Adversarial Networks
A class of AI algorithms used in unsupervised machine learning, implemented by a system of two neural networks contesting with each other.
GPT
Generative Pre-trained Transformer
A class of language processing models particularly known for their ability to generate coherent and contextually relevant text.
GRU
Gated Recurrent Unit
A type of RNN that simplifies learning in sequential tasks. It uses gating mechanisms to control information flow.

LSTM
Long Short-Term Memory
A type of RNN that can remember long sequences of data, improving performance in tasks like speech recognition.
ML
Machine Learning
A subset of AI that involves the practice of using algorithms to parse data, learn from it, and then make a determination or prediction.
NARROW AI
Narrow Artificial Intelligence
AI systems designed to perform specific tasks, operating under a limited set of constraints. (Also known as "Weak AI".)
NLP
Natural Language Processing
A branch of AI that helps computers understand, interpret, and manipulate human language.
RL
Reinforcement Learning
A type of ML where an agent learns to behave in an environment, by performing actions and seeing the results.
RNN
Recurrent Neural Networks
A type of ANN designed to recognize patterns in sequences of data, such as text, genomes, handwriting, or spoken word.
