I am a research scientist with broad interests in machine learning and artificial intelligence. My work on large scale learning and stochastic gradient algorithms has received attention in the recent years. I am also known for the DjVu document compression system. I joined Facebook AI Research in March 2015.

Borges and AI

Léon Bottou and Bernhard Schölkopf https://arxiv.org/abs/2310.01425

We started this work mid-2022. AI was already turning into a mainstream topic. Both as a scientist and a member of the society, I was troubled by the ambient confusion between the actual AI technology and the AI of our dreams or nightmares. We seem unable to grasp this technology and its impact without referring to an AI mythology that maybe starts with Homer's golden maiden and was popularized by modern science fiction.

Therefore we decided to instead interpret the advances of AI using a very different lens: the fiction of Jorge Luis Borges, whose subtly ironical stories illuminate how language works and relates to reality. This intellectual exercise turned into a very fruitful exercise, one that has reframed our outlook on AI:

  • It clarifies the relation between AI and language models, or fiction machines.
  • It explains how humans perceive these technologies, searching for vindications that comfort our preconceptions, vainly attempting to purify the fiction machine, or trusting this modern Pythia over our own reason.
  • It also explains how fiction machines should be seen as tools to construct theories for both real and imagined worlds. The ability to create fictional stories —so-called “hallucinations”— is crucially important. For instance, to understand a factual story, say a historical battle, we must be able to imagine how different circumstance or decisions would have changed the events. This provides a new meaning to Pat Winston's claim about the centrality of story making and story telling.
  • And finally, it shows the importance how understanding the world through the right story. For instance, understanding the weather patterns through the mood of the Gods only went so far. Yet it took centuries to readjust.

From Causal Graphs to Causal Invariance

Pointing out the very well written report Causality for Machine Learning recently published by Cloudera's Fast Forward Labs. Nisha Muktewar and Chris Wallace must have put a lot of work into this. This report stands out because they have a complete section about Causal Invariance and they neatly summarizes the purpose of our own Invariant Risk Minimization with beautiful experimental results.

Graph Transducer Networks explained

I was scavenging my old emails a couple weeks ago and found a copy of an early technical report that not only describes Graph Transformer Networks in a couple pages but also explains why they are defined the way they are.
