  • Why is the 'multi-label none' field important in the dataset?

    -The 'multi-label none' field is important because it allows the model to learn and classify land parcels that do not have any of the specified features, such as neither a swimming pool nor a solar panel.

  • What are some parameters that can be adjusted when training a deep learning model in ArcGIS Pro?

    -Parameters that can be adjusted include the number of epochs, batch size, chip size, learning rate, and the choice of different model backbones. Additionally, the validation set can be split differently, and the processing environment, such as using a GPU, can be specified.

    -Inference is performed using the 'Classify Objects Using Deep Learning' tool, where the user provides the input features, the trained model definition, and can adjust the batch size and environment settings, such as using a GPU for faster processing.

  • What does the confidence score in the inference results indicate?

    -The confidence score represents the model's certainty in its classification of a feature. A higher score indicates a higher confidence in the assigned labels.

  • How does the multi-label feature classifier help in automating the survey of residential properties?

    -The multi-label feature classifier automates the survey process by classifying features with multiple attributes, reducing the time required from weeks to months to just a few hours, making the process more efficient.

Keywords

💡Multi-label Feature Classifier

A multi-label feature classifier is a type of machine learning model that is capable of assigning more than one class or label to a single feature. This is in contrast to traditional classifiers that assign a single label to each feature. In the context of the video, it is used to classify land parcel polygons as having features like swimming pools and solar panels, which can coexist on the same parcel.

💡ArcGIS Pro

ArcGIS Pro is a powerful geographic information system (GIS) software developed by Esri. It is used for creating, editing, analyzing, and visualizing geographic information. In the video, ArcGIS Pro is utilized to implement the multi-label feature classification process, showcasing its capabilities in handling spatial data analysis.

💡Deep Learning Model

A deep learning model refers to artificial neural networks with multiple layers that can learn complex patterns from data. These models are a subset of machine learning algorithms capable of high-level abstraction and are particularly effective for tasks like image and speech recognition. In the video, a deep learning model is trained to classify features in land parcel polygons based on their attributes, such as the presence of a swimming pool or solar panel.

💡Land Parcel Polygons

Land parcel polygons are geographical representations used in GIS to denote areas of land that are typically used for property identification and management. In the video, these polygons are the primary data objects being classified, with the multi-label feature classifier determining the presence of amenities like swimming pools and solar panels on each parcel.

💡Attribute Table

An attribute table in GIS is a database table associated with a feature layer that stores information about the features in the layer. It contains columns and rows where each row represents a feature, and each column represents an attribute of the feature. In the video, the attribute table is used to show the presence or absence of features like swimming pools and solar panels, which are then used to train the multi-label classifier.

💡Export Training Data

Exporting training data is the process of preparing and saving a dataset that will be used to train a machine learning model. This data is typically structured in a way that the model can learn from it. In the video, the step involves exporting the label data set from the land parcel polygons to be used for training the deep learning model.

💡Model Training

Model training is the phase in machine learning where the model learns from the training data to make predictions or classifications. It involves adjusting the model's parameters to minimize errors. In the context of the video, the deep learning model is trained using the exported data set of land parcel polygons, with the goal of classifying the presence of features like swimming pools and solar panels.

💡Inference

Inference in machine learning is the process of using a trained model to make predictions or classifications on new, unseen data. It is the application of the learned patterns to understand or make decisions about the data. In the video, inference is performed using the trained deep learning model to classify the features of land parcel polygons in ArcGIS Pro.

💡Batch Size

Batch size in machine learning refers to the number of training examples used in one iteration. It is a hyperparameter that can affect the performance and speed of training. Larger batch sizes can lead to faster training but may require more memory. In the video, the presenter mentions adjusting the batch size based on the available memory or GPU memory during model training.

💡GPU

A GPU, or Graphics Processing Unit, is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. In the context of the video, the presenter uses a GPU to speed up the training process of the deep learning model due to its ability to handle parallel computations more efficiently than a CPU.

💡Confidence Score

A confidence score in machine learning is a numerical value that represents the model's certainty in its predictions. Higher scores indicate higher confidence. In the video, the model provides confidence scores for its classifications of land parcel polygons, such as the presence of a swimming pool or solar panel, with values like 0.99 indicating high confidence in the classification.
