Topic: Point-based Neural Radiance Fields
Abstract:
3D scene reconstruction is one of the core problems for 3D understanding. Reconstructing 3D scenes from 2D Images are among the hardest but most useful tasks for autonomous agents. In contrast to rendering, which obtains 2D images from 3D scenes, this task is a reverse rendering problem and can be solved by optimizing a differentiable rendering model with backpropagation.
The current state-of-the-art reverse rendering model utilizes implicit functions such as neural radiance fields (NeRF) to represent the 3D scene. However, it can only be optimized per-scene and not scalable. On the other hand, deep multi-view stereo methods can quickly reconstruct scene geometry via direct network inference. We propose point-based neural radiance fields that combine explicit (points) and Implicit (neural radiance fields) representation by using neural 3D point clouds, with associated neural features, to model a radiance field. Our model has potential to be rendered efficiently by aggregating neural point features near scene surfaces, in a ray marching-based rendering pipeline.

Speaker: Bahar Jalali-Farahani, Technical Lead, Cisco
Talk Title: Toward Tbps Optical and Wireline Communication: a Circuit Design Perspective
Series: Integrated Systems
Abstract: The demand for higher data rate communication has never been greater than today. Driven by
emerging technologies particularly IoT and cloud computing, higher capacity is required both in core
networking as well as computing applications. A report by the IEEE Ethernet Bandwidth Assessment ad
hoc group stated that "global demand for network bandwidth is growing at such an alarming rate that
terabit-speed networks will be the only way to support capacity, should current trends continue through
2015". This brings new challenges for circuit designer community as higher speed and better energy
efficiency are expected from building blocks of such communication systems.
This talk starts with an introduction to the two major category of optical communication; IMDD (Intensity
Modulated Direct Detect) vs Coherent detection. Pros, cons, and application of each are discussed and the
general architecture of receivers and transmitters in these systems are given. The talk then reviews the
latest trends in the design of high-speed transimpedance amplifiers and modulator drivers. Some examples
of co-design and co-optimization with optics are presented.
Biography: Bahar Jalali-Farahani received her PhD in electrical engineering from The Ohio
State University in 2005. During her PhD program, she was working with the data
converter research group at Freescale Semiconductor in Tempe, AZ where she was
responsible for developing digital calibration techniques for high resolution data
converters. She joined the department of electrical engineering at Arizona State
University in January 2006 and continued her research on digitally assisted high
performance analog circuits, and low-power circuit techniques. From 2011 to 2014
she was with Cisco Systems working on design of high-speed components for
Silicon-Photonics-based 100Gb Ethernet. In 2014 she joined Nokia Bell Labs in NJ
where she was a major contributor to the development of Nokia's Wavence products, multi-standard
microwave links used for long haul and short haul applications. Since September 2017 She has been with
Acacia Communications (now part of Cisco) working on millimeter-wave front ends for Silicon-Photonics
coherent receivers.
