    Study Notes

    Unsupervised Learning

    • Involves training a machine learning model on an unlabeled dataset to identify patterns and relationships without prior knowledge of the output.
    • Example: a topic modeling model trained on a dataset of news articles to identify underlying topics without knowing what those topics are in advance.

    Deep Learning

    • A subset of machine learning that involves training neural networks with multiple layers to learn complex patterns in data.
    • Has been used successfully in natural language processing (NLP) tasks, including language translation, text summarization, and sentiment analysis.

    Machine Learning

    • A field of computer science and artificial intelligence that focuses on developing algorithms and statistical models to enable computers to learn from data and make predictions or decisions without being explicitly programmed.
    • Goal is to create systems that can automatically improve their performance on a specific task by learning from experience.
    • Can be used in conjunction with ABM to enhance the ability of agents to learn and adapt to changing environments.

    Types of Machine Learning

    • Supervised Learning: algorithm is trained on a labeled dataset, where the correct output for each input is provided.
    • Unsupervised Learning: algorithm is trained on an unlabeled dataset, and the model learns to identify patterns in the data and group similar data points together.
    • Semi-supervised Learning: algorithm is trained on a combination of labeled and unlabeled data.

    Text Mining

    • Can be used to analyze social media posts, news articles, and other text data to identify opinions and attitudes of the public on various issues.
    • Can be used to analyze online reviews and user-generated content to identify features and attributes important to consumers when adopting new products or technologies.
    • Often uses machine learning approaches to analyze and extract insights from unstructured text data.

    Applying Machine Learning and Text Mining

    • Can be used to analyze public opinion and inform the behavior of agents in an ABM simulation of public opinion.
    • Can be used to study the diffusion of innovations and inform the behavior of agents in an ABM simulation of the diffusion of innovations.
    • Can be used to model political systems and inform the behavior of agents in an ABM simulation of political systems.

    Combining Machine Learning and Agent-Based Modeling

    • Can provide predictive power that exceeds traditional aggregate methods.
    • Requires high-resolution time series data.
    • Can enable researchers and decision-makers to gain deeper insights into complex systems and phenomena, and to make more informed decisions based on real-world data.
