Introduction
Deep learning has revolutionized the field of artificial intelligence, especially in object detection and computer vision tasks. However, with the exponential growth in the size and complexity of models, training these architectures has become increasingly challenging. Synvision faced several obstacles in its deep learning workflows, including extended training durations, resource-intensive processes, and the lack of robust solutions for rapid experimentation. This case study delves into the challenges, solutions, and outcomes achieved by Synvision through a custom approach.
Key Challenges
Exponential Model Growth: While deep learning has seen significant advancements, the increasing size of state-of-the-art models has led to resource and time constraints. Training large models demands substantial computational power and time, creating a bottleneck for rapid deployment.
Extended Training Time: Training an object detection model using cutting-edge architectures typically requires 2-4 weeks. This prolonged duration limits the ability to iterate quickly and respond to new project requirements.
Limited Transfer Learning Support: Newer architectures, particularly one-shot learning models, often lack robust transfer learning capabilities. This limitation forces teams to train models from scratch, further extending the development cycle.
Rapid Testing and Validation: The need for rapid testing and validation of new models is critical to ensure agility in development cycles. Existing workflows made this difficult due to inefficiencies in data handling and infrastructure.
Cloud-Based Training Limitations: Training models on cloud-based platforms, such as TAO, presented challenges including:
Frequent debugging and fixing to achieve proper training.
High costs associated with cloud resources for model training.
Lack of robustness in existing solutions, requiring extensive manual intervention.
Solution
To overcome these challenges, Synvision developed a custom scripted pipeline over PyTorch. This pipeline streamlines the entire lifecycle of deep learning model development, from data collection to deployment. Key components of the solution include:
Comprehensive Data Lifecycle Management:
Data collection, batching, annotation, and verification were standardized using tools like CVAT.
Efficient data handling ensures smooth integration into the training process.
Custom Model Development Pipeline:
Synvision’s pipeline supports model selection, baselining, parameter tuning, and experimentation.
A smaller subset of data is utilized for quick experimentation, drastically reducing the training time.
Best Practices Implementation:
Infrastructure and data handling practices were standardized, optimizing resource utilization.
Model building practices emphasized modularity and reusability.
Optimized Training Workflow:
Smaller, more efficient models were prioritized to reduce resource consumption.
Training workflows were optimized to achieve up to 5x better training times.
Standardized Inference Pipeline:
Leveraging OpenCV, PyTorch, TensorRT, DeepStream, and Docker, a standardized inference pipeline was created.
This ensured smooth deployment and scalability of trained models.
Outcomes
The implementation of this custom pipeline resulted in significant improvements across various aspects of model training and deployment:
Efficient Data Standardization: Standard operating procedures (SOPs) for data handling using CVAT improved the speed and accuracy of the annotation process.
Quick Model Experimentation: The ability to conduct rapid experimentation with smaller datasets accelerated the testing of new models.
Reduced Training Time: Training durations were reduced by up to 5 times, enabling quicker iterations and faster time-to-market.
Resource Optimization: By focusing on smaller models and efficient workflows, resource consumption was significantly reduced.
Seamless Deployment: The standardized inference pipeline ensured smooth integration with existing systems and reduced deployment challenges.
Conclusion : Deep Learning Model Training
Synvision’s innovative approach to overcoming the challenges of deep learning model training demonstrates the power of custom solutions tailored to specific needs. By leveraging a scripted PyTorch pipeline, the company achieved remarkable improvements in training efficiency, resource utilization, and deployment agility. This case study underscores the importance of standardization, best practices, and innovative thinking in tackling the evolving demands of deep learning.
Synvision’s success story serves as an inspiration for organizations striving to optimize their AI workflows while maintaining cost-effectiveness and agility in a competitive landscape.
