What is pre-trained model in machine learning?

Experience Level: Junior
Tags: Machine learning


A pre-trained model is a machine learning model that has been trained on a large dataset and is available for use in solving similar problems. Instead of starting from scratch, a pre-trained model can be used as a starting point and fine-tuned to a specific problem or task. Pre-trained models are particularly useful in deep learning, where training a model from scratch can be computationally intensive and time-consuming.

Pre-trained models can be used in a variety of applications, including computer vision, natural language processing, and speech recognition. For example, in computer vision, pre-trained models such as VGG, ResNet, and Inception have been trained on large datasets such as ImageNet and can be used for tasks such as image classification, object detection, and image segmentation.

Pre-trained models are often made available through open-source libraries and can be accessed and used by developers and researchers for their own projects. However, it is important to note that pre-trained models may not always be suitable for every application and may need to be fine-tuned or modified to achieve optimal performance for a specific task.
