The development and assessment of bias mitigation methods require rigorous benchmarks.
This paper introduces BMBench, a comprehensive benchmarking framework to evaluate bias
mitigation strategies across multitask machine learning predictions (binary classification,
multiclass classification, regression, and clustering). Our benchmark leverages state-of-the-art
and proposed datasets to improve fairness research, offering a broad spectrum of fairness
metrics for a robust evaluation of bias mitigation methods. We provide an open-source repository
to allow researchers to test and refine their bias mitigation approaches easily,
promoting advancements in the creation of fair machine learning models.

Using <i>nerfies</i> you can create fun visual effects. This Dolly zoom effect
would be impossible without nerfies since it would require going through a wall.

There's a lot of excellent work that was introduced around the same time as ours.
</p>
<p>
<a href="https://arxiv.org/abs/2104.09125" target="_blank">Progressive Encoding for Neural Optimization</a> introduces an idea similar to our windowed position encoding for coarse-to-fine optimization.
</p>
<p>
<a href="https://www.albertpumarola.com/research/D-NeRF/index.html" target="_blank">D-NeRF</a> and <a href="https://gvv.mpi-inf.mpg.de/projects/nonrigid_nerf/" target="_blank">NR-NeRF</a>
both use deformation fields to model non-rigid scenes.
</p>
<p>
Some works model videos with a NeRF by directly modulating the density, such as <a href="https://video-nerf.github.io/" target="_blank">Video-NeRF</a>, <a href="https://www.cs.cornell.edu/~zl548/NSFF/" target="_blank">NSFF</a>, and <a href="https://neural-3d-video.github.io/" target="_blank">DyNeRF</a>
</p>
<p>
There are probably many more by the time you are reading this.
