Google BERT (Bidirectional Encoder Representations from Transformers) was released on October 11, 2018. In 2019, integrated Google Search.

The AI system AlphaGo by DeepMind Google defeats the Go world champion Lee Sedol.

The Deep Blue is a chess-playing computer developed by IBM that defeated world chess champion Gary Kasparov.

The first chatbot ELIZA, was created in 1966 by Joseph Weizenbaum at MIT.

John McCarthy used the term “Artificial Intelligence” at the Dartmouth Conference, and then it became popular.

The Turing Test was introduced by English mathematician Alan Turing, to test that tries to measure whether the other person is an artificial intelligence or a real human in a dialogue.

The Artificial Neuron Model (McCulloch & Pitts) is the first mathematical model of a neuron and a foundational concept in artificial intelligence and neural networks.

Warren McCulloch (neuroscientist) and Walter Pitts (logician) proposed a neuron model to describe how neurons can be represented as basic logical and mathematical units.

How the Model Works (A Simple Explanation)

• Receives multiple binary inputs (0 or 1)
• Multiplies each input by a fixed weight
• Sums the weighted inputs
• Compares the result to a threshold
• Produces a binary output (0 or 1)
