Study Notes
Rational Behavior and Decision Making
- Rational behavior can be described using mathematical terms.
- Two rational agents may hold different opinions about a subjective probability.
Case-Based Reasoning
- Case-Based Reasoning uses a distance measure to compare a new problem with stored examples in the case-base.
- The steps of the CBR cycle are:
- RETRIEVE: find the most similar case to the query using a similarity measure.
- REVISE: adapt the solution from the retrieved case to fit the query context.
- RETAIN: make further changes to the solution as needed after trying it out.
- REUSE: store the final case in the case-base, if necessary.
Hidden Markov Models
- Stationarity is assumed in Hidden Markov models to induce conditional independencies, making calculations more efficient.
- The computational cost of smoothing in Hidden Markov Models grows linearly with the number of observed time-steps.
- Both the Markov assumption and the sensor Markov assumption must be made when using Hidden Markov Models.
Reinforcement Learning and Deep Learning
- Reinforcement learning is not a type of deep learning.
- Deep learning models prefer high-dimensional data and are prone to overfitting.
- Weight regularization is a technique used to avoid overfitting in deep learning.
Markov Decision Processes
- Changing the discount factor in a Markov decision process can affect the optimal policy.
- For some Markov decision processes, one iteration of value iteration can be faster than one iteration of policy iteration.
Natural Language Processing
- Word embeddings translate words to vector representations.
- Word embeddings are beneficial because they change the input representation from a single binary to a high-level vector.
- Probabilistic models for natural language are still useful in conjunction with deep learning models.
- Monogram/Bag-of-Word representations are not necessarily better at capturing sentence structure than Trigram models.
- Major challenges for language models include natural language being ambiguous, subjective, and used inconsistently.
