How does transfer learning works?

How does transfer learning work? Transfer learning means taking the relevant parts of a pre-trained machine learning model and applying it to a new but similar problem. In supervised machine learning, models are trained to complete specific tasks from labelled data during the development process.

What is transfer learning with example?

Transfer learning (TL) is a research problem in machine learning (ML) that focuses on storing knowledge gained while solving one problem and applying it to a different but related problem. For example, knowledge gained while learning to recognize cars could apply when trying to recognize trucks.

How do I learn transfer learning?

Transfer learning scenarios

  1. Remove the fully connected layers near the end of the pretrained base ConvNet.
  2. Add a new fully connected layer that matches the number of classes in the target dataset.
  3. Randomize the weights of the new fully connected layer and freeze all the weights from the pre-trained network.

What does transfer learning mean?

Transfer learning is the application of knowledge gained from completing one task to help solve a different, but related, problem. Through transfer learning, methods are developed to transfer knowledge from one or more of these source tasks to improve learning in a related target task.

Can we use GPU for faster computations in Tensorflow?

GPUs are great for deep learning because the type of calculations they were designed to process are the same as those encountered in deep learning. This makes deep learning algorithms run several times faster on a GPU compared to a CPU.

Why does transfer learning fail?

When there is a mismatch in the domain between the dataset for pretext tasks and the downstream task, the transfer learning may not work. The pre-trained models may converge but it will be stuck in a local minimum. Thus, the performance will not be better than training from scratch.
