Top 20 Interview Questions on Keras You Must Practice

If you are into deep learning and artificial intelligence, you must be familiar with Keras. One of the most popular Deep Learning frameworks – Keras has become the go-to choice of Data Scientists due to its smooth, high-level, and user-friendly interface. Keras has made it easier for Data Science beginners to dive into deep learning and easily develop applications without getting trapped into complex computations.

With the field of deep learning growing every day, its applications and demand have also increased exponentially. Companies and Data Scientists are actively using deep learning frameworks such as Keras and TensorFlow to develop desired models and applications. 

Consequently, when hiring for a Data Scientist, companies look for candidates with extensive knowledge of Deep Learning and AI along with hands-on experience in Keras and TensorFlow. If you’re interviewing for a Data Scientist position that involves tasks in deep learning and AI, you are likely to be asked questions on these frameworks.

To help you prepare, in this article we’ll discuss the top 20 questions on Keras you can be asked in Data Scientist interviews. Earlier, we talked about interview questions on Tensor. Let’s get started.
