Professor Mert Pilanci from Stanford University talks about his recent breakthroughs in machine learning. He discusses the challenges of training AI models, the limitations of gradient descent, and current trends in AI. He also explores different approaches to resolving deep learning issues and the potential of utilizing convex optimization for larger neural networks.
Training shallow neural networks can be transformed into super-efficient algorithms that achieve the best accuracy on the first shot.
Convex optimization theory can be used to find global optimum or close approximations for deep neural networks, but it requires increased computation time.

AI is the collective endeavor to create computer programs that mimic human intelligence
AI aims to simulate or mimic human intelligence by replicating human-like capabilities such as perception, planning, and problem-solving. Neural networks are currently synonymous with AI, although the lack of understanding of their inner workings presents challenges.
Challenges in training AI: high cost and poor optimization algorithms
Training AI systems, particularly deep neural networks, is time-consuming and energy-intensive. These challenges arise mainly from the use of poor optimization algorithms. Gradient descent, commonly used for training neural networks, is a basic and primitive method that performs poorly on non-convex problems.
Applying convex optimization theory to deep neural networks
Researchers are exploring the application of convex optimization theory to address challenges in training deep neural networks. By recasting neural network models as convex optimization problems in higher dimensional spaces, the global optimum or close approximations can be found. However, this approach comes with the trade-off of increased dimensionality, which requires more computation time.
The importance of shallow neural networks and sequential training
While deep neural networks offer impressive performance, practical applications often require shallow networks. Shallow neural networks can benefit from more efficient optimization algorithms, resulting in faster and more stable training. In cases where deep networks are necessary, techniques like sequential training, training layers at a time, can help achieve similar performance despite some loss in optimality.
We have great pleasure of hosting Mert Pilanci, Professor at Stanford University. Mert Pilanci shares with us his recent research breakthroughs in machine learning. Mert and his group discovered that the training of shallow neural networks can be transformed into super-efficient algorithms that always achieve the best accuracy possible on the first shot.
