Eliminate the time-consuming process of building and fine-tuning Deep Neural Networks (DNNs) from scratch for Intelligent Video Analytics (IVA) applications.

The term “transfer learning” implies that you can extract learned features from an existing neural network and transfer these learned features by transferring weight from an existing neural network. The pre-trained models accelerate the developer’s deep learning training process and eliminate higher costs associated with large scale data collection, labeling, and training models from scratch. Transfer Learning Toolkit enables you to build high performance IVA based applications such as retail analytics, logistics, smart cities, access control and more.

The Transfer Learning Toolkit is a python-based toolkit that enables developers to take advantage of NVIDIA’s pre-trained models and offers capabilities for developers to adapt popular network architectures and backbones to their own data, train, fine tune, prune and export for deployment. The simple interface and abstraction improves the efficiency of the deep learning training workflow.

Key Capabilities

  • GPU optimized pre trained weights for computer vision tasks
  • Easily modify configuration files for adding new classes and retraining models with custom data
  • Perform model adaptation and retraining in heterogeneous multi- GPU environments
  • Reduce model sizes using pruning functionality
  • Model Export API for deployment on NVIDIA DeepStream SDK with NVIDIA Tesla and Jetson products
  • Jupyter notebook examples for object classification and detection use cases

Enabling End to End Deep Learning Workflow for Intelligent Video Analytics

For developers designing and integrating IVA end applications such as parking management, securing critical infrastructure, retail analytics, logistics management and access control, etc. NVIDIA provides end to end deep learning workflow with DeepStream SDK for AI-based video and image understanding, as well as multi-sensor processing. DeepStream and Transfer Learning Toolkit together are an integral part of NVIDIA Metropolis, the platform for building end-to-end services and solutions for transforming pixels and sensor data to actionable insights.
