Introduction

This module provides an overview of the key AI technologies powering modern applications. We'll explore machine learning, deep learning, natural language processing, computer vision, and other AI technologies, helping you understand which tools are appropriate for different business problems.

The AI Technology Stack

AI isn't a single technology but a collection of techniques and tools:

Foundation Layer: Machine Learning

Machine Learning (ML) is the foundation of most modern AI. Instead of explicitly programming rules, ML systems learn patterns from data.

Three Main Types:

Deep Learning: Neural Networks

Deep learning uses artificial neural networks with many layers to learn complex patterns. It excels at:

🔑 Understanding Neural Networks

Neural networks are inspired by the human brain:

  • Neurons (Nodes): Individual processing units that perform simple calculations
  • Layers: Neurons organized in layers (input, hidden, output)
  • Connections (Weights): Links between neurons with adjustable strengths
  • Learning: Adjusting connection weights based on training data

Deep networks have many hidden layers, allowing them to learn hierarchical representations (edges → shapes → objects in image recognition).

Natural Language Processing (NLP)

NLP enables computers to understand, interpret, and generate human language.

Key NLP Capabilities

Modern NLP: Transformers and LLMs

Transformer Architecture: Revolutionary neural network design that powers modern NLP

Large Language Models (LLMs):

🔬 LLMs vs. Neurosymbolic AI: Technical Comparison

How LLMs Work:

  • Predict next word based on statistical patterns learned from training data
  • No explicit knowledge representation or reasoning mechanism
  • Everything learned is encoded in billions of numerical parameters
  • Cannot easily update knowledge without retraining

How Neurosymbolic AI Works:

  • Neural Component: Learns patterns from data (like LLMs)
  • Symbolic Component: Explicit knowledge graphs, rules, and logic
  • Integration: Neural predictions constrained and enhanced by symbolic reasoning
  • Updating: Can update symbolic knowledge without retraining neural component
Characteristic Pure LLMs Neurosymbolic AI
Knowledge Representation Implicit in parameters Explicit + implicit
Reasoning Pattern matching Logical + pattern matching
Explainability Difficult Traceable reasoning paths
Reliability Can hallucinate Rules prevent certain errors
Domain Integration Through prompts/fine-tuning Direct encoding of expertise
Best For General language tasks Regulated, critical decisions

When to Use Each:

  • LLMs: Content generation, general Q&A, creative writing, translation
  • Neurosymbolic: Compliance checking, medical diagnosis, financial analysis, legal reasoning—anywhere explainability and reliability are critical

Computer Vision

Computer vision enables machines to understand and interpret visual information.

Key Computer Vision Tasks

Business Applications

Speech and Audio AI

Speech Recognition (Speech-to-Text)

Converting spoken language into written text:

Speech Synthesis (Text-to-Speech)

Generating natural-sounding speech from text:

Speaker Recognition

Identifying who is speaking:

Recommendation Systems

AI systems that predict user preferences and suggest relevant items.

Types of Recommendation Approaches

Business Applications

Predictive Analytics

Using historical data to predict future outcomes.

Common Prediction Tasks

Business Applications

Malta Tourism Company: AI-Powered Experience Recommendation

Business Context: A Malta-based tourism company offering various experiences (historical tours, boat trips, diving, restaurants) wanted to personalize recommendations to increase booking conversion and customer satisfaction.

The Challenge:

  • Generic recommendations led to low conversion (8% of site visitors booked)
  • Customers overwhelmed by 200+ experience options
  • Missed cross-selling opportunities (customers booked average 1.2 experiences)
  • No way to leverage past customer preferences
  • Seasonal variations in demand not considered

The AI Solution:

  • Hybrid Recommendation System: Combined collaborative filtering (similar tourists' choices) with content-based filtering (experience characteristics)
  • Multi-Factor Inputs: Customer demographics, booking history, browsing behavior, time of year, weather forecast, event calendar
  • Contextual Ranking: Personalized ordering of experiences based on predicted preference
  • Explainable Recommendations: Showed reasons ("Popular with families in June" or "Matches your diving interest")
  • A/B Testing: Continuously tested recommendation strategies

Results After 8 Months:

  • Booking conversion increased from 8% to 14.5%
  • Average experiences per customer rose from 1.2 to 2.4
  • Customer satisfaction scores improved by 23%
  • Revenue per visitor increased by 85%
  • Reduced customer service inquiries ("What should I do?") by 40%

Technical Insights:

  • Started with simple collaborative filtering, then added complexity
  • Cold start problem solved by using demographic and contextual data for new users
  • Seasonal patterns crucial—diving recommendations vary by weather and sea conditions
  • Explainability increased trust and click-through rates

Robotic Process Automation (RPA) Enhanced with AI

RPA automates repetitive tasks; AI makes it smarter.

Traditional RPA

AI-Enhanced RPA (Intelligent Automation)

Business Applications

Choosing the Right AI Technology

💡 Decision Framework

For Language Tasks:

  • Simple classification/sentiment → Traditional ML (faster, cheaper)
  • Complex language understanding → LLMs or Transformers
  • Regulated decisions needing explainability → Neurosymbolic AI

For Vision Tasks:

  • Simple object detection → Pre-trained models (YOLO, Faster R-CNN)
  • Specialized domain (medical images) → Fine-tuned deep learning
  • Real-time performance critical → Edge AI with optimized models

For Prediction Tasks:

  • Structured data, explainability needed → Tree-based models (XGBoost, Random Forest)
  • Large datasets, complex patterns → Deep learning
  • Limited data → Traditional ML with feature engineering
