Turing Test and Machine Intelligence
Can a computer think?
Are there imaginable digital computers which
would do well in the imitation game?"
The contest requires at least 30% (50%) of
judges take machine as a human!
Main variations: Standard Test (Loebner Prize), and Imitation Game
Critics: focus on human behavior, and not intelligence
AI has focused on intelligence, and on specific goals/tasks, and not on mimicking humans.
- Some human behavior are not intelligent (typing mistakes, lie, …)
- Some intelligent behavior are inhuman (solving difficult computational problems)

Human Intelligence vs. Machine Intelligence
Analytical Skills
Synthetic Skills
 Cognitive skills that machines excel at
would take intellectual efforts from human
 Cognitive skills that human performs
effortlessly but hard for machines with current
AI
– Mathematical calculations, making logical
decisions in complex situations, chess
 Computational Intelligence
– Manipulation of symbols through
algorithmic information processing
– The processing units (processing device)
does not know or care about the
“meaning” of symbol
– Cognition by “information processing”, or
cognition as computation
– Interpretation of subtle facial expressions,
engaging in creative conversations, etc.
 Conscious intelligence
– Symbol manipulation also happens in the lowest level
of hierarchical structure of brain function
– The higher levels of hierarchical structure of brain
function involve emergent concepts where higher level
concepts/ideas combine, and form complex organisms
(analogy with ‘cloud’, a whole, relation to air and water
molecules, component)
– It is at this level of cognition that “understanding of
meaning” arise

A major challenge towards winning Touring Test: Building knowledge bases
 “For an artifact, a computational intelligence, to be able to behave with high levels of performance on
complex intellectual tasks, perhaps surpassing human level, it must have extensive knowledge of the
domain”
 The challenge of AI in making progress toward building human-like artifacts:
– Knowledge representation, and (especially) knowledge acquisition
 Approaches
– Build a large knowledge base by reading text
– Distilling from the WWW a huge knowledge base
EDWARD A. FEIGENBAUM, Some Challenges and Grand Challenges for
Computational Intelligence, Journal of the ACM, Vol. 50, No. 1, January 2003, pp. 32–40
 Semantic Web and Linked Data methods over the last decade extensively has explored building models,
ontologies and rule-set that contributes to WWW knowledge representation
– Manual, and semi-automated, focused on curated ontologies
– Community participation in building ontologies have resulted in creation of large knowledge bases:
DBPedia, Yago, Wikidata, Freebase, MediaWiki, etc.
– Ontologies are expensive to build and scale, and are generic in nature

Lesson Learned from Watson (1): scalable knowledge model building method
 “The Watson program is already a breakthrough technology in AI. For many years it had been largely
assumed that for a computer to go beyond search and really be able to perform complex human language
tasks it needed to do one of two things: either it would “understand” the texts using some kind of deep
“knowledge representation,” or it would have a complex statistical model based on millions of texts.”
– James Hendler, Watson goes to college: How the world’s smartest PC will revolutionize AI, GigaOm, 3/2/2013
 Breakthrough:
– Developing a systematic approach for scalable knowledge building over large, less reliable data sources,
and deploying a large array of individually imperfect algorithms to find right answers
• Building and curating a robust, and comprehensive knowledge base and ruleset is laborious, time
consuming and slow

• Watson approach for building on massive, mixed curated and not-curated and less reliable information
sources with uncertainty has proved effective

Cognitive Assistant
 A software agent (cog) that
– “augments human intelligence” (Engelbart’s definition1 in 1962)
– Performs tasks and offer services (assists human in decision making and taking actions)
– Complements human by offering capabilities that is beyond the ordinary power and reach of human (intelligence
amplification)
 A more technical definition
– Cognitive Assistant offers computational capabilities typically based on Natural Language Processing (NLP),
Machine Learning (ML), and reasoning chains, on large amount of data, which provides cognition powers that
augment and scale human intelligence
 Getting us closer to the vision painted for human-machine partnership in 1960:
– “The hope is that, in not too many years, human brains and computing machines will be coupled together very
tightly, and that the resulting partnership will think as no human brain has ever thought and process data in a way
not approached by the information handling machines we know today”

Deep Learning
Deep learning is a branch of machine learning based on a set of algorithms that attempt to model high-level abstractions in
data by using multiple processing layers with complex structures, or otherwise composed of multiple non-linear transformations
(Wikipedia Definition)
 Most successful form of deep learning algorithms
– Artificial Neural Networks (ANNs)
• We have had good algorithm for training ANNs with 1-hidden layer, Deep Learning focuses on training ANNs with
multiple hidden layers, at scale
 Deep learning methods use a cascade of many layers of nonlinear processing units for feature extraction and transformation
 Are hierarchical in learning the model (different levels of abstractions), favor unsupervised (and probabilistic) feature
extraction and transformation
 Other examples: Deep Boltzmann Machine (DBM), a binary pair-wise Markov random field, Multi-layer Kernel Machines
(MKM), Deep Q-Networks (Google DeepMind)
 Applications
– Speech recognition, Image recognition, NLP
 Libraries
– Torch, Theano, OpenNN, TensorFlow (Google), etc.
 Latest Development
– Modeling Order in Neural Word Embeddings at Scale, 32nd International Conference on Machine Learning, 2015.
– Digital Reasoning: training largest neural network with 160 Billion parameters (Google’s record was 11.2 Billion)
– Achieved 85.8% accuracy, up from 76.2% (Google), with few hours/days of training time on commodity hardware

– How to build a user model for the Cog?
 Adaptation and training of Cogs for a new domain
– How to quickly train a cog for a new domain? Current approaches is laborious and tedious.
 Performance Dimensions, and Evaluation Framework
– Metrics, testing and validating functionality of Cog
– Are controlled experiments possible?
– Do we need to test in Real environment with Real users
 User adoption/trust, and privacy

What is best for the human to do? What is best for the cog?
© 2013 IBM Corporation
Open Challenges (2)
 Teaching the Cog what to do
– Learning from demonstration, Learning from documentation
– Telling the Cog what to do using natural language
– Interactive learning where the Cog may ask questions of the trainer
– How does the Cog learn what to do, reliably?
– Active learning where the Cog improves over time
• Moving up the learning curve (how does Cog understand the goal/desired end state?)
• Adapts as the environment (e.g., data sources and formats change)
– On what conditions should the Cog report back to the Human?
– Task composition (of subtasks) and reuse
– Adaptation of past learning to new situation
 Proactive Action taking
– Initiating actions based on learning and incoming requests
• E.g., deciding what information sources to search for the request , issuing queries, evaluating
responses
– Deciding on next steps based on results or whether it needs further guidance from Human
 Personal knowledge representation and reasoning
– Capturing user behavior, interaction in form of personal knowledge
– Ability to build knowledge from various structured and unstructured information
– AI Principle: expert knows 70,000+/- 20,000 information pieces, and human tasks involves 1010
rules
(foundation of AI, 1988)
© 2013 IBM Corporation
Open Challenges (3)
 Context understanding, and context-aware interaction
– Modeling the world of the person serving, including all context around the work/task, and
being able to use the contextual and environmental awareness to proactively and reactively
act on behalf of the user
 Learning to understand the task and plan to do it
– Understanding the meaning of tasks, and coming up with a response (e.g.. How many
people replied to an invite over email, accepting the offer, without asking the Cog to do so),
or suggestions on how to achieve it (based on any new information discovered by the Cog)
 Cognitive Speech recognition, or other human-computer interfaces for communicating with Cogs
– Improving the speech-to-text techniques, and personalized, semantic-enriched speech
understanding
– Non-speech based approaches for communicating with humans
© 2013 IBM Corporation
