Convolutional Neural Network (CNN): A specialized type of neural network designed to process structured grid data like images. CNNs are commonly used in image recognition, computer vision, and video analysis.
Cross-Validation: A statistical method used to estimate the performance of a machine learning model by dividing data into subsets, training the model on some subsets, and validating it on others. This helps in evaluating model accuracy and avoiding overfitting.

Data Mining: The process of discovering patterns, correlations, and insights from large datasets using various techniques such as machine learning, statistics, and database systems.
Data Science: A multidisciplinary field that uses scientific methods, processes, algorithms, and systems to extract knowledge and insights from structured and unstructured data. It encompasses machine learning, statistics, and data analysis.
Deep Learning: A subset of machine learning that uses neural networks with many layers (deep neural networks) to learn from vast amounts of data. Deep learning is used for complex tasks such as image and speech recognition, natural language processing, and autonomous driving.
Decision Tree: A machine learning model that makes decisions based on a series of binary choices, similar to a flowchart. Each node represents a decision point, and each branch represents the possible outcomes.

Edge AI: AI computation that takes place directly on devices at the “edge” of the network, closer to the data source, rather than relying on cloud computing. This approach reduces latency and improves response times for applications like autonomous vehicles and IoT devices.
Explainable AI (XAI): AI systems designed to be transparent in their decision-making process, allowing users to understand how and why decisions are made. This is critical for trust, accountability, and regulatory compliance.

Feature Engineering: The process of selecting, modifying, or creating new features (variables) from raw data to improve the performance of a machine learning model. Effective feature engineering can significantly enhance model accuracy.
Feature Extraction: A technique used to reduce the dimensionality of data by selecting only the most important features that contribute to the prediction or classification task. Common in image and text processing.
Federated Learning: A decentralized machine learning approach where models are trained collaboratively across multiple devices without sharing the underlying data, preserving privacy and security.

Generative Adversarial Networks (GANs): A class of machine learning models consisting of two neural networks (a generator and a discriminator) that compete against each other to create realistic data samples, such as images or videos. GANs are used for tasks like image synthesis, data augmentation, and style transfer.
Gradient Descent: An optimization algorithm used to minimize the loss function of a machine learning model by iteratively adjusting model parameters. It is fundamental to training deep learning models.

Hyperparameters: The settings or configurations that define the structure of a machine learning model (e.g., the number of layers in a neural network, the learning rate). Unlike model parameters, hyperparameters are set before the training process begins and are tuned to optimize model performance.

Inferencing: The process of using a trained machine learning model to make predictions or decisions on new, unseen data. It is the deployment phase of a machine learning model.
Internet of Things (IoT): A network of interconnected devices that collect, exchange, and analyze data using AI to provide insights and automation in areas like smart homes, health monitoring, and industrial automation.

Label: A value or category used to identify the output or target of a machine learning model. In supervised learning, labels are used to train models by providing the correct answers for a set of inputs.
Learning Rate: A hyperparameter that controls how much the model’s weights are updated with respect to the loss gradient during each iteration of training. A lower learning rate makes the training process slower but more precise, while a higher rate speeds up training but may overshoot optimal parameters.
Long Short-Term Memory (LSTM): A type of recurrent neural network (RNN) architecture that is well-suited for sequence prediction problems, such as time-series forecasting, natural language processing, and speech recognition. LSTMs can learn long-term dependencies and maintain information over extended periods.

Machine Learning (ML): A subset of AI that focuses on building systems that learn from data to make predictions or decisions. Types of machine learning include supervised, unsupervised, and reinforcement learning.
Model Training: The process of teaching a machine learning model by feeding it data and adjusting its parameters to minimize error and improve accuracy.
