High-Performance AND Cost Savings in Neural Network Training?  

Jun 7, 2023


Neural networks have emerged as powerful tools for solving complex problems in various domains, including computer vision, natural language processing, and robotics. However, deploying neural networks in real-world applications requires addressing several challenges, such as handling out-of-distribution examples, dealing with adversarial attacks, and reducing input data and processing costs. In this series of articles, we’ll explore the concept of robustness in neural network training, its advantages and consequences, and the methods for implementing robustness during and after the neural network training. We’ll also discuss how robustness can lead to cost savings in different industries. 

Robustness in a nutshell   

Neural networks have revolutionized many industries, from self-driving cars to personalized healthcare. However, these models often fail in unexpected ways when deployed in real-world scenarios. For instance, a self-driving car may not recognize a pedestrian wearing a dark hoodie, leading to a potentially dangerous situation. Similarly, a chatbot may give inappropriate responses to sensitive topics due to biases in the training data. To address these challenges, researchers have focused on improving the robustness of neural networks, which refers to their ability to perform well on input data that is different from the training data.

In other words, a robust neural network can handle noisy, corrupted, or adversarial examples that are not present in the training set. Robustness is crucial for ensuring the reliability, safety, and fairness of neural network-based systems.

Advantages and challenges of Robustness  

Robustness brings several advantages to neural network training, including: 

Improved performance on out-of-distribution examples: In many real-world scenarios, the input data may not match the distribution of the training data. For instance, a medical imaging system may encounter rare diseases that are not present in the training set. A robust neural network can handle such out-of-distribution examples by generalizing well to unseen data. 

Reduced sensitivity to adversarial attacks: Adversarial attacks refer to the deliberate manipulation of input data to fool the neural network. For instance, adding imperceptible noise to an image can make the network misclassify it with high confidence. A robust neural network can detect and resist such attacks, which is crucial for security-critical applications like defense, finance, and healthcare. 

However, there are also some trade-offs to consider when implementing robustness. For example, a more robust AI system may sacrifice some accuracy on clean data, or it may require more computational resources to train and run. Implementing robustness often requires additional layers, modules, or training steps in the neural network pipeline, which can increase its complexity and computational cost. This can make the training process slower and more resource-intensive, especially for large-scale models. Additionally, some robustness techniques may not be applicable to all types of data or tasks.
