A Gentle Introduction to Imbalanced #Classification
After completing this tutorial, you will know:
* Imbalanced classification is the problem of classification when there is an unequal distribution of classes in the training dataset.
* The imbalance in the class distribution may vary, but a severe imbalance is more challenging to model and may require specialized techniques.
* Many real-world classification problems have an imbalanced class distribution, such as fraud detection, spam detection, and churn prediction.

A Gentle Introduction to Imbalanced Classification
Classification predictive modeling involves predicting a class label for a given observation. An imbalanced classification problem is an example of a classification problem where the distribution of examples across the known classes is biased or skewed. The…

Triple #GenerativeAdversarialNetworks
Generative adversarial networks (GANs) have shown promise in image generation and classification given limited supervision. Existing methods extend the unsupervised GAN framework to incorporate supervision heuristically. Specifically, a single discriminator plays two incompatible roles of identifying fake samples and predicting labels and it only estimates the data without considering the labels. The formulation intrinsically causes two problems: (1) the generator and the discriminator (i.e., the classifier) may not converge to the data distribution at the same time; and (2) the generator cannot control the semantics of the generated samples. In this paper, we present the triple generative adversarial network (Triple-GAN), which consists of three players—a generator, a classifier, and a discriminator. The generator and the classifier characterize the conditional distributions between images and labels, and the discriminator solely focuses on identifying fake image-label pairs. We design compatible objective functions to ensure that the distributions characterized by the generator and the classifier converge to the data distribution. We evaluate Triple-GAN in two challenging settings, namely, semi-supervised learning and the extreme low data regime. In both settings, Triple-GAN can achieve state-of-the-art classification results among deep generative models and generate meaningful samples in a specific class simultaneously.

Hyperparameter Tuning On #Google Cloud Platform With #Scikit_Learn
Google Cloud Platform’s AI Platform (formerly ML Engine) offers a hyperparameter tuning service for your models. Why should you take the extra time and effort to learn how to use it instead of just running the code you already have on a virtual machine? Are the benefits worth the extra time and effort?
