What is an ntk?

NTK stands for Neural Tangent Kernel, a concept in machine learning and deep learning research. NTKs are mathematical objects used to analyze the training dynamics of certain neural networks, especially in the infinite-width limit. They help researchers understand how neural networks learn and generalize by relating them to kernel methods. NTKs are primarily relevant in theoretical machine learning research and are not typically job titles held by professionals. If you encountered 'NTK' as a job title, it's possible it refers to something specific to a company or industry, so it's important to clarify the context.
