  • Prediction of bank customer churn model using pytorch machine learning classification in Python

    Time:2021-9-7

    Classification problems belong to the category of machine learning problems. Given a set of functions, the task is to predict discrete values. Some common examples of classification questions are predicting whether a tumor is cancer or whether a student is likely to pass an exam. In this paper, given some characteristics of bank customers, we […]

  • Image classification for deep learning

    Time:2021-8-16

    Deep learning image classification resnet50 This time, transfer learning is adopted and fine tuned. The general recommendations are: Feature extraction using pre trained models: when using small data sets, the common practice is to use the features learned from the models trained on larger data sets in the same domain. This is done by instantiating […]
