    Study Notes

    Machine Learning Fundamentals

    • An algorithm in the context of machine learning is a set of instructions that is used to train a computer to perform a specific task.

    Types of Learning

    • Supervised Learning: involves training a computer algorithm on input data that has been labeled for a certain output.
    • Unsupervised Learning: the main objective is to identify patterns or structure in the data without a specific output in mind.
    • Reinforcement Learning: an intelligent agent learns to operate within an environment by receiving rewards or penalties for its actions.

    Neural Networks

    • Origin of Neural Networks: proposed by Warren McCulloch and Walter Pitts in 1944.
    • Unsupervised Learning: involves the use of AI systems to find patterns in data sets without labeled data points.
    • Neural Network Memory: differs from human memory in that it is distributed and stored in the connections between neurons.
    • Performance Improvement: a neural network's performance allows it to continuously improve through backpropagation and optimization of weights.

    Biological Brain vs. Artificial Neural Networks

    • Energy Consumption: the energy consumption of a biological brain is significantly lower than that of artificial neural networks.
    • Size: the human brain is much larger and more complex than an artificial neural network.
    • Energy Efficiency: artificial constructions cannot match the energy efficiency level of a biological brain due to the complexity and dynamic nature of biological neurons.

    Neural Network Memory vs. Human Memory

    • Storage: a well-trained neural network can store and recall vast amounts of information, but lacks the contextual understanding and emotional associations of human memory.
