Softmax Regression (synonyms: Multinomial Logistic, Maximum Entropy Classifier, or just Multi-class Logistic Regression) is a generalization of logistic regression that we can use for multi-class classification
The “classic” application of logistic regression model is binary classification. However, we can also use “flavors” of logistic to tackle multi-class classification problems, e.g., using the One-vs-All or One-vs-One approaches, via the related softmax regression / multinomial logistic regres...
This could be cross-entropy for classification tasks, mean squared error for regression, etc. Choose an optimizer and set hyperparameters like learning rate and batch size. After this, train the modified model using your task-specific dataset. As you train, the model’s parameters are adjusted ...
Deep learning is a subfield of Machine Learning, focused on a specific category of models known as Neural Networks. Needless to say, these can get dramatically more complicated than the simple linear regression example. GPT-3, for example, had an astounding 175 billion parameters. However, simply...
Face classification loss is a softmax loss for binary classes (face/not face). Face box regression loss – The target bounding boxes are normalized and are in the format [(x_center, y_center, width, height]). Facial landmark regression loss – This regression technique also normalizes the...
For example, if you have a multi-class classification task, you should set the objective to “multi:softmax”5. Alternatively, if you have a binary classification problem, you can use the logistic regression objective “binary:logistic”. Now you can use your training set to train the model...

With K = 2, softmax regression is same as binary logistic regression. Overall, with softmax regression scheme, we can solve the classification problem not just for K = 2, but also for many possible values of K. Softmax regression is often used as the activation function in the ...
Regression is performed using open-source platforms such as Darknet, TensorFlow, or PyTorch. The final output of the object recognition algorithm comprises the categorization of object class along with details of its bounding box to specify the exact location of the object in the image. Did you ...
and essentially carries out a weighted sum of its inputs, applies an offset (or "bias") and then a non-linear transformation function (called "activation"). Different arrangements of these components have been used to describe decision boundaries in classification, regression functions and other st...
