Jul 18, 2022 · Image classification is a supervised learning problem: define a set of target classes (objects to identify in images), and train a model to recognize them using labeled example photos. Early computer vision models relied on raw pixel data as the input to the model.

Jan 22, 2025 · Their job is to perform classification based on the features extracted by the convolutions. Typically, the final fully connected layer contains a softmax activation function, which outputs a probability value from 0 to 1 for each …

Mar 3, 2025 · Learn how to calculate three key classification metrics—accuracy, precision, recall—and how to choose the appropriate metric to evaluate a given binary classification model.

Jul 18, 2022 · Exercise 1: Build a Convnet for Cat-vs.-Dog Classification. In this exercise, you'll get practical, hands-on experience with convolutional neural networks. You'll build an image classifier from scratch to distinguish photos of cats from photos of dogs:

Mar 13, 2024 · Machine Learning APIs. Machine Learning (ML) is a powerful technique for analyzing Earth Observation data. Earth Engine has built-in capabilities to allow users to build and use ML models for common scenarios with easy-to-use APIs. A common ML task is to classify the pixels in satellite imagery into two or more categories.

Jul 18, 2022 · But what if you could leverage existing image models trained on enormous datasets, such as via TensorFlow-Slim, and adapt them for use in your own classification tasks?

Apr 15, 2025 · Learn how to interpret an ROC curve and its AUC value to evaluate a binary classification model over all possible classification thresholds.
