This article is an ultimate guide, crafted by the GATE experts at GFG, to help you start your journey of learning for GATE (Graduate Aptitude Test in Engineering) Data Science and AI in 100 Days in a systematic manner.
There are many overlaps when it comes to data science and artificial intelligence (AI). AI has many smaller subsets, like machine learning and deep learning. Data science uses these technologies to interpret and analyze data and find trends and patterns to make predictions. So, the choice between AI vs data science can be tricky.
Machine Learning (ML) depends on strong data science practices to get relevant data in training the ML algorithms and systems. Data science is a field that requires the knowledge of both Artificial Intelligence (AI) and Machine Learning (ML), and many AI careers, like an AI engineer, need the skills of a data scientist.
The demand for data science and AI skills is only increasing by the day. If you preparing for GATE 2024 or looking for a last 3-month preparation strategy?, this is the best place to get a roadmap of your Data Science and AI learning journey along with all the latest job-oriented technologies, designed according to the latest GATE Syllabus.
