AI-900: Confidence vs Accuracy vs RMSE vs Sentiment in Image Classification

Learn the difference between confidence, accuracy, RMSE, and sentiment in image classification. Confidence is the probability of a correct classification, accuracy is the percentage of correct classifications, RMSE is the deviation of the predictions from the labels, and sentiment is the emotional tone of the input.


To complete the sentence, select the appropriate option in the answer area.

__________ is the calculated probability of a correct image classification.

A. Accuracy
B. Confidence
C. Root Mean Square Error
D. Sentiment


B. Confidence


The correct answer is B. Confidence.

Confidence is the calculated probability of a correct image classification. It indicates how confident the model is that the input image belongs to a certain category. For example, if the model assigns a confidence score of 0.9 to the category “dog” for an input image, it means that the model is 90% sure that the image is a dog. Confidence is usually calculated by the output layer of the neural network, which produces a vector of scores for each possible category. The higher the score, the higher the confidence.

Accuracy is a measure of how well the model performs on a set of images that have known labels. It is calculated by dividing the number of correctly classified images by the total number of images. Accuracy is a metric that evaluates the model after it has been trained and tested, not during the classification process.

Root Mean Square Error (RMSE) is a measure of how much the model’s predictions deviate from the actual labels. It is calculated by taking the square root of the average of the squared differences between the predictions and the labels. RMSE is a metric that evaluates the model’s performance on a continuous output, such as regression, not on a categorical output, such as classification.

Sentiment is a measure of the emotional tone or attitude of a text, image, or speech. It is usually expressed as positive, negative, or neutral. Sentiment is a type of natural language processing (NLP) task, not an image classification task.
