Supervised Learning At The Heart of AI

➢ Using Machine Learning (ML), we are able to learn these complex non-linear functions / programs

that are not algorithmic in nature

➢ Current ML applications make use of supervised learning

➢ A lot of labeled data need to be available in order to ensure generalization

✓ Generalization – the ability of the machine to produce sensible answers on new inputs that it

has never seen during training

Artificial Intelligence – The Technology of The Future 10

Deep Neural Networks Are A Powerful Method

➢ Researchers have succeeded in training deep neural networks

➢ They consist of many layers of differentiable non-linear transformations

✓ Learn a hierarchical feature representation along side the objective and can be trained

end-to-end

• Early layers learn low-level features such as edges and corners

• Later layers combine these features to obtain “face” features or “ear” features

• The last layer of the model then computes the output from this high-level

representation

Some Challenges Remain

And Need To Be Tackled

Page 16: Knowledgeable Independent Focused · Source: Convolutional Deep Belief Networks for Scalable Unsupervised Learning of Hierarchical Representations, Honglak Lee, Roger Grosse, Rajesh

Artificial Intelligence – The Technology of The Future

➢ Current AI approaches are extremely good at learning complicated functions provided that enough data is available

✓ In domains where little labeled data is available, Deep Learning (DL) will likely fail

➢ DL models are mostly unable to transfer learned knowledge across different domains

➢ As a rule of thumb we can currently solve most of the problems that would require a second of thought by a human

✓ General understanding as we humans have is thus still far away

✓ There is neither a clear road to achieve this

How Powerful Are Current Methods?

Artificial Intelligence – The Technology of The Future

➢ Deep Networks are black-box architectures, which makes it difficult to evaluate how a model has

learned the task

Source: worldlife.org

✓ If the network has learned about the presence of ice instead of the color of the bear skin, it will wrongly

predict the right image to be of a brown bear

➢ Generalization performance helps evaluate the learned knowledge, but is always limited

➢ This may be problematic in which an incorrect decision may affect human lives

✓ Medical diagnoses and self-driving cars are clear examples of this

Artificial Intelligence – The Technology of The Future

➢ An agent (model) observes an environment and interacts with it by means of actions

✓ The environment provides feedback to the agent in the form of rewards

✓ The agent learns to act in order to maximize its reward

➢ Many problems can be modelled in this context, i.e. control, trading, interaction

✓ However the credit-assignment problem makes learning difficult: The agent does not know, which (sequence of)

action(s) caused a positive reward

➢ There is a lot of ongoing research in this domain and current techniques are increasingly being applied in practice

Artificial Intelligence – The Technology of The Future

➢ Superintelligence could happen in decades or centuries, many of the top AI experts

disagree

✓ However recent advances in AI have revived the debate concerning AI safety

➢ Two common failure cases can be considered

✓ An AI is programmed to do harm

• Autonomous weapons - need not be robots

✓ An AI is programmed to do good but implements a destructive strategy in achieving its

goal

• Researchers / Practitioners could fail in aligning the goals of an AI with our

goals through misspecification (example: paperclip factory)

➢ The objective is to align the goals of an AI with ours before it becomes superintelligent

✓ Develop methods to evaluate what an AI has learned and be able to test its goals

✓ Learn how to raise an AI in order to have it adopt our goals and beliefs

Artificial Intelligence – The Technology of The Future

➢ A more serious and immediate concern than the superhuman intelligence scenario

➢ But we are not yet at a point where massive job losses are imminent

✓ However, AI is expected to replace a lot of educated jobs in the near future

➢ Which jobs are currently at risk?

✓ Jobs that are well-defined / have an exact outcome and for which a lot of labelled training data is

available

✓ For example translators, radiologists, taxi-drivers, planners / logistics managers

➢ The closer we get to Artificial General Intelligence, the more jobs are expected to be on the line

✓ Until we have reached that point, AI will also offer a lot of new job opportunities

Will AI Affect Jobs?
