[takes me back to my engineering geology days in the Southern Hemisphere, including my thesis – with a healthy dose of spatial analysis and modeling – and all with a specific use; what is not to like?]

photo - terraces in part of the Ticsani Valley, Peruphotos - (A) The main fluvial landforms in the AOI. The Carumas river can be seen here to be bounded by landslides affecting a fluvial terrace covered by agricultural terraces. (B) Landslides affecting a slope close to a community in the AOI. Note the construction of terraces on prior landslide deposits.schematic / cross-section - Typical profile of terraces built in Southern Peru. Wall rocks are directly piled over an excavated trench in bedrock without mortar. An upward decreasing gradation is used to fill the internal portion of the wall in compacted layers. Fertile arable soil is placed in the top 30 cm.imagery / map / schematic cross-section - (A) A 3D view of the San Cristobal landslide. (B) A 1:50,000 geological map of the landslide area, modified from [33]. Ki-mat = Matalaque Fm. P-Pi = Puno Fm. Q-pl = colluvial deposits, debris avalanche. Qp-vl-pi = pyroclastic deposits. Red line marks the topographic cross-section shown in A. (C) Cross-section of the San Cristobal landslide with estimated base groundwater conditions (blue) and materials boundaries (green) to be used for modeling and interpreted potential failure surfaces (dashed red).

@cnDuKeli @tcdh

The approach they used for #classifying the poems' function in the narrative were interesting, using #LLMs. Performance is pretty bad so far. Keli took up the call for #openness about #failure from a session this morning and showed that the different models are bad in different ways, which allowed the team (and us) to learn something about the models. I think that's great and valuable!

Nice to see specificity and sensitivity uhhhh specified in a discussion of test kit results abc7news.com/health/bay-area-d
