Understanding AI Algorithms The Building Blocks
The Essence of AI Algorithms
Essentially AI algorithms are collections of instructions or rules that allow machines to carry out tasks generally requiring intelligence of a human nature. Examples of these types of tasks would include learning from data, making predictions and identifying patterns in data. The quality of and design of the algorithm largely determines the effectiveness of an AI system.
The first example is supervised learning predicting the future. Supervised learning involves training an AI model on a “labeled” dataset which means the input data is matched with the correct output. Then the model learns to predict the output when it is given new unfound data. Common algorithms in supervised learning include:
- Multiple Regression Analysis: This technique involves predicting continuous values which are to follow within set patterns if the required independent values are given.
- Logistic Regression: Employed for binary classification tasks like spam detection.
- Support Vector Machines (SVMs): These techniques are especially suited to solve both classification and regression problems.
- Neural Networks: These algorithms inspired by the human brain are for more complex pattern recognition tasks.
For example in filtering email messages supervised learning algorithms can make classifications for messages as either ‘spam’ or ‘not spam’ based on features discovered from the content of the email.
Unsupervised Learning Discovering The Hidden
Unsupervised learning models work with unlabeled data seeking to identify inherent structures or patterns without predefined categories. Key techniques include:
- Clustering: Grouping data points with similar characteristics. For example customer segmentation in marketing.
- Association: Identifying rules that characterize a large portion of data such as identifying which products are purchased together.
- Dimensionality Reduction: Reducing datasets to simpler datasets by combining the variables which might be done with Principal Component Analysis (PCA).
An example of unsupervised learning is market basket analysis when retailers look for patterns of which products are most frequently purchased so they can place them in the most advantageous inventory location.
Reinforcement Learning Learning through Mistakes
Reinforcement learning refers to a machine learning method that enables the agent to learn how to make decisions by taking actions and receiving rewards and/or penalties as feedback. Think of it like training a pet with treats for good behavior. Applications include:
- Building Artificial Intelligence: Creating agents that are capable of playing well at games such as chess or Go.
- Robotics: Learning by exploring and/or practicing tasks for a robot-made.
- Autonomous Vehicles: Teaching a self-driving car to navigate roadways using rewards for safe driving behaviors.
Deep Learning Dynamics Fueling Innovation in AI
Deep learning is a type of machine learning which uses two or more layers of neural networks hence ‘deep’ for fact-finding analyses from data of different types.
- Game AI: Designing agents that can play and master games like chess or Go.
- Robotics: Teaching the robot to learn a task by exploration and/or simple practice.
- Autonomous Vehicles: Teaching a self-driving car to navigate roads with welfare given to driving behaviors recognized as safe.
These models have revolutionized fields such as:
- Computer Vision is basically establishing machines to understand as well as process visual information.
- Speech Recognition converting spoken language into written text.
- Natural Language Processing (NLP) involves letting machines understand and generate human language.
- Convolutional Neural Networks have advanced in a big way toward image recognition technologies including facial recognition and medical imaging.

- Part-of-Speech Tagging (POS tagging)
- Sentiment Analysis
- Text Classification
- Word Embeddings (e.g. Word2Vec, GloVe)
- Bag of Words (BoW)
- TF-IDF (Term Frequency-Inverse Document Frequency)
- Stopword Removal
- Dependency Parsing
- Modeling
- Chatbots and Conversational Agents
- Language Modeling
- Transformer Models (e.g. BERT, GPT)
- Sequence-to-Sequence Models
- Intent Recognition
- Contextual Embeddings
