How machine learning can be used to identify microplastics

Fast Company Tech

The width of a human hair, for comparison, ranges from 20 to 200 micrometers. When scientists collect samples from the environment to study microplastics, they usually want to know more about the chemical identities of the microplastic particles found in the samples. Most scientific studies focus on microplastics in water.

Detecting novel systemic biomarkers in external eye photos

Google Research AI blog

The comparison with a clinicodemographic baseline is useful because risk for some diseases could also be assessed using a simple questionnaire , and we seek to understand if the model interpreting images is doing better. due to the multiple comparisons problem ). Top: Sample images scaled to different sizes for this experiment.

Preference learning with automated feedback for cache eviction

Google Research AI blog

The reward model is a lightweight neural network that is continuously trained with ongoing automated feedback on preference comparisons designed to mimic the offline oracle. To address these issues, HALP first applies an inexpensive heuristic scoring rule that corresponds to an eviction priority to identify a small candidate sample.

Bursting at the seams: Candid’s largest nonprofit compensation report yet  

Candid

Candid’s team also added 21 new metropolitan statistical areas (MSAs) to the report this year to allow for greater geographic comparisons. This allowed us to produce the most complete analysis of fiscal year 2021 and illuminate the continued impact that 2020 had on the sector.

Pop the champagne: This year Candid’s grants data set turns 21!

Candid

2002-2012 – Childhood During the first 10 years, Candid staff primarily focused on collecting grants of $10,000 or more awarded by a sample of the largest U.S. 2013-2014 – Tweens A decade in, the importance of consistent year-over-year comparisons grew. Analysis tip : We still create these annual data sets.

Sony’s first AI image sensor will make cameras everywhere smarter

The Verge

Instead of sending off data to be analyzed, either to the cloud or a nearby processor, the image sensor itself performs whatever AI analysis is necessary and simply produces the metadata instead. Test samples of the IMX500 have already started shipping to early customers with prices starting at ¥10,000 ($93). milliseconds.

Running Code and Failing Models

DataRobot

My hope is that this analysis can increase awareness about data science mistakes and raise the standards for machine learning in research. For example, last year I shared an analysis of a project by Harvard and Google researchers that contained fundamental errors. For comparison, a random forest model achieves 2.38 Conclusion.
