Introduction: In machine learning, It’s the technique that allows models to leverage knowledge gained while solving one problem and apply it to a different, but related, task. This capability has revolutionized various fields, from computer vision to natural language processing. Understanding Transfer Learning: Transfer learning operates on the premise that knowledge acquired from solving one task can be transferred to another task, even if they are not directly related. Instead of training a model from scratch each time for a new task, transfer learning enables the reuse of pre-trained models or their learned features, thus significantly reducing the need for…
