With approximately 300 million parameters, it&#8217;s a small but mighty tool, perfect for mobile and edge devices where resources are limited.<\/p>\n\n\n\n<p>One of the standout features of Embedding Gemma is its versatility. Built on the Gemma 3 architecture, it offers multilingual support for over 100 languages [<a target=\"_blank\" rel=\"noreferrer noopener\" href=\"http:\/\/www.youtube.com\/watch?v=420x8bv1la0&amp;t=70\">01:10<\/a>]. This makes it a highly flexible tool for global applications. Furthermore, the model allows for customizable output dimensions, letting you balance accuracy and performance [<a target=\"_blank\" rel=\"noreferrer noopener\" href=\"http:\/\/www.youtube.com\/watch?v=420x8bv1la0&amp;t=86\">01:26<\/a>]. You can reduce the output from a maximum of 768 down to 128 dimensions, which is a great way to save on compute cost and speed, though it comes with a slight trade-off in accuracy.<\/p>\n\n\n\n<p>Beyond basic search, Embedding Gemma can be applied to a wide range of Natural Language Processing tasks, including classification, topic modeling, and question answering. It can even be used for more complex functions like fact-checking, reranking, and summarization.<\/p>\n\n\n\n<p>A practical example highlighted in the video demonstrates how to build a simple RAG system with the <code>transformers<\/code> package [<a target=\"_blank\" rel=\"noreferrer noopener\" href=\"http:\/\/www.youtube.com\/watch?v=420x8bv1la0&amp;t=493\">08:13<\/a>]. Using a corpus of HR and leave policies, the model can efficiently retrieve the most relevant information to answer a user&#8217;s question, such as &#8220;how do I reset my password?&#8221;.<\/p>\n\n\n\n<p>For those who need to tailor the model to specific needs, fine-tuning is an option [<a target=\"_blank\" rel=\"noreferrer noopener\" href=\"http:\/\/www.youtube.com\/watch?v=420x8bv1la0&amp;t=578\">09:38<\/a>]. By using a dataset with anchor, positive, and negative examples, you can improve the model&#8217;s similarity scores for your unique use case.<\/p>\n\n\n\n<p>In conclusion, Embedding Gemma is an excellent choice for anyone looking for a lightweight, efficient, and versatile solution for on-device retrieval.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Retrieval-Augmented Generation (RAG) is a powerful technique for enhancing large language models (LLMs), but running it on-device has always been a challenge.
