2. Peter Norvig, Google Research Today we will watch a Youtube video: Peter Norvig, Director of Research, Google Google Developers Day talk: Theorizing from Data Covers some Google tools beyond keyword-search And statistical language models behind the tools Video is 37 minutes long, plus questions from the audience (skip these?)

3. Watch out for… The rise of probabilistic, statistical (Markov or N-gram) models More Data is better than Better Algorithms (Banko & Brill) Google N-gram Corpus: WWW freqs of words, word-pairs, … New Google tools: Google Sets, Google Trends, … Question-Answering: how to extract facts from WWW Statistical Machine Translation, learning from aligned texts How many bits are needed to store probabilities? (4!!) To save space, truncate words – to how many letters? (4!!) Google AI tools dont try to replace human intelligence – they AUGMENT intelligence
