Evolution of Machine Learning for practical use
Machine Learning (ML) has played a pivotal role in advancing Natural Language Processing (NLP), enabling computers to understand, interpret, and generate human language. This Markdown file explores the evolution of ML in NLP through key timelines, milestones, and advancements.
Early Developments (1950s-1980s)
- 1950s:
- Alan Turing introduces the Turing Test as a measure of a machine’s ability to exhibit intelligent behavior indistinguishable from that of a human.
- 1956:
- John McCarthy coins the term “Artificial Intelligence” (AI) at the Dartmouth Conference, laying the foundation for AI research.
- 1960s-1970s:
- Shakey the Robot, developed at Stanford Research Institute, demonstrates early attempts at natural language understanding and interaction.
- 1970s-1980s:
- Rule-based systems dominate early NLP approaches, using handcrafted rules and linguistic principles for tasks like syntax parsing and machine translation.
Statistical Revolution (1980s-1990s)
- 1980s:
- Hidden Markov Models (HMMs) and n-gram models emerge as dominant statistical techniques in speech recognition and language modeling.
- 1990s:
- Statistical Machine Translation (SMT) becomes prominent, leveraging large corpora and statistical models for automated translation systems.
Rise of Machine Learning (2000s-2010s)
