lede = introductory section in journalism

Allegedly, it’s spelled ‘lede’ to avoid confusion with ‘lead,’ which was the strip of metal that would separate lines of type.

Today let us read Baydin et al (2018) Automatic Differentiation in Machine Learning: A Survey

arxiv.org/pdf/1502.05767

I have screenshotted the first three paragraphs of the introduction. It reads:

Methods for the computation of derivatives in computer programs can be classified into four
categories: (1) manually working out derivatives and coding them; (2) numerical differentiation using finite difference approximations; (3) symbolic differentiation using expression
manipulation in computer algebra systems such as Mathematica, Maxima, and Maple; and
(4) automatic differentiation, also called algorithmic differentiation, which is the subject
matter of this paper.
Conventionally, many methods in machine learning have required the evaluation of
derivatives and most of the traditional learning algorithms have relied on the computation of gradients and Hessians of an objective function (Sra et al., 2011). When introducing
new models, machine learning researchers have spent considerable effort on the manual
derivation of analytical derivatives to subsequently plug these into standard optimization
procedures such as L-BFGS (Zhu et al., 1997) or stochastic gradient descent (Bottou, 1998).
Manual differentiation is time consuming and prone to error. Of the other alternatives, numerical differentiation is simple to implement but can be highly inaccurate due to round-off
and truncation errors (Jerrell, 1997); more importantly, it scales poorly for gradients, rendering it inappropriate for machine learning where gradients with respect to millions of
parameters are commonly needed. Symbolic differentiation addresses the weaknesses of
both the manual and numerical methods, but often results in complex and cryptic expressions plagued with the problem of “expression swell” (Corliss, 1988). Furthermore, manual
and symbolic methods require models to be defined as closed-form expressions, ruling out
or severely limiting algorithmic control flow and expressivity.
We are concerned with the powerful fourth technique, automatic differentiation (AD).
AD performs a non-standard interpretation of a given c…

Highlight of my day was not just having lunch with the amazing Claudia Goldin, but learning she's responsible for my favourite kitchen item: my ice cream scoop.

She has not just been an inspiration for my professional life but has also directly, heavily improved my personal life!

What a star.

I wanted to get a video of this ghost crab but every time I got close to their hole they scuttled back in, so I tried getting clever with it. I made a little sandcastle and shoved my phone into it, hit record, and walked away. Crab was VERY suspicious of this addition to their environment.
