Introduction
• Artificial intelligence (AI)• The science and engineering of making
intelligent machines (John McCarthy, 1956)• The study and design of intelligent
agents/systems (Science Daily)• AI• Uses insights from many fields (computer
science, psychology, linguistics, economics, etc.)• Relevant to robotics development, facial
recognition software, speech recognition software, etc.
Turing Test
• Created by Alan Turing in 1951• Began as a game to see if a judge could tell the
difference between a computer and a human• Now the goal is to develop software/programs
that can accurately process human language and generate appropriate responses
• Loebner prize offered every year; No winners yet
Turing Test
• Can Machines think?• “Can this machine consistently fool
users into believing it is human?”
Turing Test
June 7, 2014, University of Reading
Eugene Goostman, a chatbot
33% of judges fooled Controversial:
Chatbot pretended to be young with poor English skills.
Dodged questions rather than answering.
Turing Test Evaluation
• Strengths– Simple test– Wide array subject
matter• Weaknesses– The Chinese Room
Argument– Unintelligent
human behavior
ParsingAutomated parsing techniques were used on Arabic sentences, and achieved amazingly accurate results!
Speech
An artificial intelligence speech tool was built for the tonal Ibibio language.
Human speech Synthesized speech using context and tone labels
SpeechA dictation tool was constructed for Slovak speech, which achieved great performance using this model.
sounds of the sentence
the darker the RED arrow, the more likely the pointed number is to be the next word
words
the darker the BLACK arrow, the more likely the word is to correspond to a sound
Translating
A written system was developed to first capture Polish sign language, then translate it.
Text ExtractionCzech text was parsed to extract information.
Text ExtractionSample tests were given to evaluate the effectiveness of such algorithms, and accomplished decent accuracy.
The Future of AIOverview
• Uncertain• Trends in biologically inspired
techniques• Trends in statistical models with large
training data sets• Expanding into many other fields
Neuromorphic Chips
• IBM TrueNorth: 256 million synapses per chip
• Neuromorphic Engineering• Reverse engineering the brain
Semantic Search
Augmented Reality
Technological Singularity
