Measure

We express the depth of a physical object or an idea as Deep or Shallow.

In computer applications, we use “Deep copy” or “Shallow copy” of objects.

Deep Thought (CMU)

• Chess Machine (hardware and software) developed by Ph.D. students at CMU (Carnegie Mellon University).
• A Ph.D. student designed and implemented a special purpose chip to implement multi-ply search.
• Two Ph.D. students, who are Chess experts, designed and implemented the algorithms to play championship level chess.
• Two more Ph.D. students provided feedback and assistance.
• Deep Thought beat the competitors to become World Computer Chess Champion.

Deep Blue (IBM)

• IBM recruited three of the five Ph.D. graduates (who worked on Deep Thought) to develop Deep Blue and challenge Gary Kasparov (World Chess Champion) to a Best-of-five match.
• Kasparov prevailed in the first encounter, but made a costly error — a prime example of “To err is human” — to lose in the second encounter.
• IBM made intensive preparations. It hired several Grand Masters to study Kasparov’s games and techniques.

Deep Learning

• It is a form of Machine Learning.
• It has become a core subject in AI (Artificial Intelligence) courses.

Deep Sleep

• There are numerous studies about Sleep and Insomnia.
• Most people need about seven hours sleep. Sleeping more than eight hours may be detrimental to one’s well being.
• The quality of sleep (e.g. Deep sleep) is important.

Indian Word

• Deep is an Indian word meaning Light. The extended meaning is Wisdom.
• Several Indian names have “Deep” (e.g. Deepak).
• Deepavali is the Indian Festival of Lights. Some call it Diwali. During our younger days, Hindu friends would give us Indian sweets as part of their Diwali celebrations.
