Writer Contributions

Gabriel Goh: Analysis lead. Gabriel Goh first found multimodal
neurons, sketched out the undertaking path and paper define, and did
a lot of the conceptual and engineering work that allowed the workforce to
examine the fashions in a scalable method. This included growing instruments
for understanding how ideas had been constructed up and decomposed (that had been
utilized to emotion neurons), growing zero-shot neuron search (that
allowed simple discoverability of neurons), and dealing with Michael Petrov
on porting CLIP to microscope. Subsequently developed faceted function
visualization, and textual content function visualization.

Chris Olah: Labored with Gabe on the general framing of the article,
actively mentored every member of the workforce via their work offering
each excessive and low stage contributions to their sections, and contributed
to the textual content of a lot of the article, setting the stylistic tone. He labored
with Gabe on understanding the neuroscience literature and higher
understanding the related neuroscience literature. Moreover, he wrote
the sections on area neurons and developed variety function
visualization which Gabe used to create faceted function visualization

Alec Radford: Developed CLIP. First noticed that CLIP was studying
to learn. Suggested Gabriel Goh on undertaking path on a weekly foundation. Upon
the invention that CLIP was utilizing textual content to categorise photos, proposed
typographical adversarial assaults as a promising analysis path.

Shan Carter: Labored on preliminary investigation of CLIP with Gabriel
Goh. Did multimodal activation atlases to grasp the house of
multimodal representations and geometry, and neuron atlases, which
probably helped the association and show of neurons. Offered a lot
helpful recommendation on the visible presentation of concepts, and helped with many
elements of visible design.

Michael Petrov: Labored on the preliminary investigation of multimodal
neurons by implementing and scaling dataset examples. Found, with
Gabriel Goh, the unique “Spider-Man” multimodal neuron within the dataset
examples, and lots of extra multimodal neurons. Assisted lots within the
engineering of Microscope each early on, and on the finish, together with serving to
Gabriel Goh with the tough technical challenges of porting microscope
to a special backend.

Chelsea Voss†: Carried out investigation of the typographical assaults
phenomena, each by way of linear probes and zero-shot, confirming that the
assaults had been certainly actual and state-of-the-art. Proposed and efficiently
discovered “in-the-wild” assaults within the zero-shot classifier. Subsequently
wrote the part “typographical assaults”. Upon completion of this a part of
the undertaking, investigated responses of neurons to rendered textual content on
dictionary phrases. Additionally assisted with the group of neurons into
neuron playing cards.

Nick Cammarata†: Drew the connection between multimodal neurons in
neural networks and multimodal neurons within the mind, which turned the
general framing of the article. Created the conditional likelihood plots
(regional, Trump, psychological well being), labeling greater than 1500 photos,
found that unfavourable pre-ReLU activations are sometimes interpretable, and
found that neurons generally include a definite regime change between
medium and robust activations. Wrote the identification part and the emotion
sections, constructing off Gabriel’s discovery of emotion neurons and
discovering that “complicated” feelings might be damaged down into less complicated ones.
Edited the general textual content of the article and constructed infrastructure permitting
the workforce to collaborate in Markdown with embeddable parts.

Ludwig Schubert: Helped with common infrastructure.
