💡Multi-label Feature Classifier

A multi-label feature classifier is a type of machine learning model that can assign more than one label to a single feature. This is in contrast to traditional classifiers that assign a single label. In the video, it is used to classify land parcels as having multiple attributes, such as swimming pools and solar panels. This concept is central to the video's theme of using deep learning models in ArcGIS Pro for efficient data analysis.

💡Deep Learning Model

A deep learning model is a complex artificial neural network that can learn from and make decisions based on large amounts of data. In the context of the video, a deep learning model is trained to recognize and classify features in land parcels, such as the presence of swimming pools or solar panels. The model's ability to handle multi-label classification is a key aspect of the video's demonstration.

💡ArcGIS Pro

ArcGIS Pro is a geographic information system (GIS) software developed by Esri for advanced mapping, analysis, and visualization. The video demonstrates how to integrate a deep learning model with ArcGIS Pro to perform multi-label feature classification, showcasing the software's capabilities in handling complex spatial data analysis tasks.

💡Land Parcel Polygons

In the video, land parcel polygons refer to the geographical areas being analyzed. These polygons represent individual properties that are being classified based on their features, such as the presence of a swimming pool or solar panels. The polygons are the primary data input for the multi-label feature classification process.

💡Label Data Set

A label data set is a collection of data points that have been annotated with specific labels. In this video, the label data set is used to train the deep learning model. Each land parcel polygon is labeled with the presence (1) or absence (0) of features like swimming pools and solar panels, which the model learns to recognize during training.

💡Training Data

Training data is the input used to train a machine learning model. In the video, the training data consists of the labeled land parcel polygons. The model learns to associate the visual characteristics of the polygons with their corresponding labels, enabling it to classify new, unseen data accurately.

💡Inference

Inference in the context of machine learning refers to the process of applying a trained model to new data to make predictions or classifications. In the video, inference is demonstrated when the trained deep learning model is used to classify new land parcels based on their features, such as the presence of swimming pools and solar panels.

💡Export Training Data

Exporting training data is the process of preparing and saving the data in a format that can be used for training a machine learning model. In the video, this step involves exporting the labeled land parcel polygons in a specific format that the deep learning model can process, such as multi-label tiles with high-resolution imagery.

💡Attribute Table

An attribute table in GIS is a data structure that stores information about the features in a layer, such as their attributes and values. In the video, the attribute table is used to display the labels associated with each land parcel polygon, which are crucial for training and understanding the model's performance.

💡Batch Size

Batch size in machine learning refers to the number of samples processed before the model's weights are updated during training. The video mentions adjusting the batch size based on available memory, which can affect the training speed and efficiency of the deep learning model.
