Introduction to Pre-Trained Models and TensorFlow.js

Learn about pre-trained models in machine learning and how to use them in TensorFlow.js. Discover different categories of models like vision, body, text, and sound.

00:00:00 Learn about pre-trained models in machine learning and how they can be used without the need for training your own models. Explore an example of a pre-trained model known as Bert q a that performs advanced text search in a web browser and find answers to questions within any piece of text.

πŸ€” Pre-trained models have already been trained by someone else, saving time and resources.

πŸ‘©β€πŸ’» Pre-trained models are available in easy-to-use JavaScript classes for common use cases.

πŸ” Example of a pre-trained model called Bert q&a that can perform advanced text search in a web browser.

00:02:22 Learn about pre-trained models and how to use them in TensorFlow.js. Discover different categories of models like vision, body, text, and sound.

πŸ“Œ Pre-trained models can be used in web apps without a background in machine learning.

πŸ” Models exist across various categories such as vision, body, text, and sound.

🐱 Object recognition allows the detection of common objects in images using the Coco SSD model.

00:04:46 An introduction to pre-trained models, specifically the Coco SSD model, which can identify objects in images and provide real-time classification. The model can also be used for sound recognition, text toxicity detection, and face tracking.

πŸ” Pre-trained models provide more powerful object recognition by not only identifying where objects are located, but also how many exist.

πŸ–ΌοΈ Coco SSD model allows real-time object recognition in web browsers, enabling practical applications like detecting objects and sending alerts.

πŸŽ₯ Using the webcam, Coco SSD can classify objects in real-time and protect privacy as all the processing is done locally in the web browser.

πŸ”Š Sound recognition models can be used to recognize short sounds and even be retrained for custom sound recognition.

πŸ’¬ Text toxicity models can automatically identify potentially offensive text, allowing for a more pleasant user experience by hiding such content.

πŸ˜€ Face mesh model provides high-resolution face tracking and is widely used in various applications.

00:07:09 This video explores pre-trained models, showcasing the combination of face mesh with WebGL shaders for augmented reality makeup Tryon. It also highlights the use of machine learning and 3D graphics in web browsers.

πŸ“Έ Face mesh combined with webGL shaders for real-time augmented reality makeup try-on.

πŸ€– Machine learning and 3D graphics libraries like 3.js enable quick development of powerful applications.

βš™οΈ Ability to switch hardware for execution and the release of two new pose estimation models with improved accuracy and performance.

00:09:33 An overview of pre-trained models and their applications: pose estimation for hand tracking, body segmentation for human body detection, text toxicity filtering for smoother conversations, remote physiotherapy using pose estimation, and automatic size selection on fashion websites.

πŸ”‘ Pre-trained models offer various functionalities, such as pose estimation, hand pose tracking, and body segmentation.

🌐 These models have applications in human-computer interaction, web conferencing, remote physiotherapy, and enhancing fashion websites.

πŸ’‘ By combining pre-trained models with custom code, one can create innovative solutions and enhance user experiences.

00:11:58 Learn how pre-trained models can be used to create advanced visual effects in the browser without requiring machine learning expertise.

⭐ Pre-trained models can be used to replace backgrounds, add special effects, and create digital teleportation in real-time in web browsers.

🌐 These models can be accessed and used by anyone without needing a machine learning background or sending images to a server.

πŸ’‘ By combining pre-trained models with web technologies, such as WebGL shaders, WebRTC, A-frame, and free.js, new creative experiences can be created.

00:14:22 Learn how to use pre-trained models to enhance your web engineering skills. Try out different models, understand their inputs and outputs, and troubleshoot limitations. Share your findings with classmates.

⭐️ Try out pre-trained models by selecting three from the available options and exploring their documentation and live demos.

πŸ’‘ Familiarize yourself with the inputs that each model requires, such as image, text, or sound, and the outputs it provides.

πŸš€ Consider how you can integrate the models into real web applications to solve problems in your own or others' lives.
