Reinforcement Learning
In reinforcement learning, the algorithm learns by interacting with an environment and receiving feedback in the form of rewards or penalties. The goal of the algorithm is to discover optimal strategies or actions to maximize cumulative rewards over time. The application includes game playing, robotics, autonomous systems. The popular reinforcement learning algorithms are:
Despite the success of machine learning, there are several limitations that led to the development and adoption of deep learning. The key limitations of machine learning are:
- ML models rely on handcrafted features and their performance is limited to quality and relevance of these features. So, extracting informative features is challenging.

The foundations of Natural Language Processing (NLP) encompass the fundamental principles and techniques that enable machines to understand, interpret, and generate human language. Key components include:
Text Processing and Representation
Text processing and representation in NLP refer to the task to handle and transform textual data for analysis and machine learning applications. Text processing is used to manipulate and prepare textual data for analysis and text representation involves converting textual information into a format that can be efficiently processed and understood by machines. Below are the methods to process and represent text:
