In this text, we explore how IFN can be applied in various fields with clear examples to help you understand its potential.\n", "\n", "To apply the Ideal Flow Network (IFN) in your field of study, you first need to know how to extract the IFN from your data. Once you have this model, you can apply IFN to predict, generate, optimize, and control the inputs. That’s the power of IFN modeling.\n", "\n", "The first step is understanding how to derive the IFN from your data.\n", "\n" ] }, { "cell_type": "markdown", "metadata": {}, "source": [ "\n", "### How IFN Learns\n", "\n", "The Ideal Flow Network (IFN) learns from \"stories,\" where each story represents a trajectory or path through different states. Because IFN relies on these stories, how we organize the data is essential. The network can be created automatically by analyzing these stories.\n", "\n", "You can build an IFN in two ways: by creating a stochastic matrix from repeated scenarios (or \"stories\") and then constructing the IFN, or by directly generating the IFN through trajectory cycles or string signatures. The algorithm will fine-tune the flow to achieve a balanced state, known as the steady state. We use the ideal flow matrix to represent these repeated scenarios. Once the IFN is built, it can predict outcomes using a Markov Chain and can be adjusted with constraints to achieve specific performance goals.\n", "\n" ] }, { "cell_type": "markdown", "metadata": {}, "source": [ "#### Key Concepts Across Fields\n", "\n", "Before you begin, it’s important to define the following terms in the context of your field:\n", "\n", "* **Node/State**: Represents a key element within your system. Identify the different elements, events or conditions in your system (e.g., a decision, a pixel, a word, a musical note, a symptom, or an intersection).\n", "* **Link**: Represents the connection or relationship between states (e.g., the transition between decisions, neighboring pixels, or words).\n", "* **Trajectory**: The path or progression through different states.\n", "* **Flow**: The weight of movement or changes between states. It may indicates the probability or information about how one state leads to another.\n", "* **Performance**: The outcomes or results you want to achieve. The performance depends objective we’re measuring (e.g., reducing traffic congestion, improving prediction accuracy, or generating new music).\n", "* **Optimization**: The process of finding the best inputs to achieve your desired outcomes.\n", "* **Exploration**: The process of discovering new paths or states that could lead to better outcomes.\n", " \n", "Remember the following key concepts:\n", "\n", "1. **Data Organization Matters:** The way you structure your data is crucial for building an effective IFN. Incorrect representations can lead to poor models. The way you organize the data is critical to how effective the IFN will be. A poorly organized data structure can lead to an inefficient IFN that doesn’t provide accurate results. However, when properly structured, IFN can \"correct\" the flow of information and balance it into a steady state. This steady state represents the ideal conditions for the system being studied.\n", "\n", "2. **Training with Stories:** By inputting repeated \"stories\" or data sequences, you can create a stochastic matrix that eventually can represents the steady state of the system. This matrix can then be used to make predictions or generate new data.\n", "\n", "3. **No Need for Negative Samples:** Unlike many machine learning algorithms that require both positive and negative data samples, IFN only needs positive samples, simplifying the training process. IFN only requires positive samples to create its flow matrix. This makes IFN a more efficient tool for certain types of predictions. However, if you really need to train the model for both positive and negative data samples then you create separate training, once for each category. \n", " " ] }, { "cell_type": "markdown", "metadata": {}, "source": [ "\n", " \n", "Below are some examples.\n", "\n", "---\n", "\n", "#### Understanding IFN in Decision-Making\n", "\n", "**Decision-Making Basics:**\n", "- **States:** These are the different choices or situations you might encounter.\n", "- **Links:** These represent the chances of moving from one state to another or the possibility of selecting a particular choice.\n", "- **Flow:** This indicates the information and the likelihood that a certain state will occur.\n", "\n", "**Example:**\n", "Imagine you're deciding whether to go out or stay home.
