myspace_aminer: MySpace social graph
This network contains the social graph of MySpace, a social networking website which also has a strong music emphasis. A directed edge (i,j) means that user i follows user j.
This network has 854498 nodes and 6489736 edges.

Misspecified Bayesianism
An agent is a misspecified Bayesian if she updates her belief using Bayes' rule given a subjective, possibly misspecified model of her signals. This paper shows that a belief sequence is consistent with misspecified Bayesianism if the prior contains a grain of the average posterior, i.e., is a mixture of the average posterior and another distribution. A partition-based variant of the grain condition is both necessary and sufficient. Under correct specification, the grain condition reduces to th…

Anybody have access to an oscilloscope with a 100baseTX Ethernet decoder on it? Curious how fast commercial protocol decodes are compared to mine.
I'd love benchmarks:
* 2 channels, 10M points, 500 Msps, on P/N
* Simple edge trigger, saturated or nearly saturated link
* Decode to Ethernet frames
How many waveforms per second / seconds per waveform do you get?

MCFuser: High-Performance and Rapid Fusion of Memory-Bound Compute-Intensive Operators
Operator fusion, a key technique to improve data locality and alleviate GPU memory bandwidth pressure, often fails to extend to the fusion of multiple compute-intensive operators due to saturated computation throughput. However, the dynamicity of tensor dimension sizes could potentially lead to these operators becoming memory-bound, necessitating the generation of fused kernels, a task hindered by limited search spaces for fusion strategies, redundant memory access, and prolonged tuning time, l…

I'll tell you, I love my System76 #Linux laptop, but the ancient MacBook Air I just wiped and installed Linux on has way better speakers, better battery life and is much lighter. The old MBA CPU is a dog of course... Something to consider the next time you are looking for a used Linux laptop.

Misspecifications in structural equation modeling: The choice of latent variables, causal-formative constructs or composites
Empirical research in many social disciplines involves constructs that are not directly observable, such as behaviors. To model them, constructs must be operationalized using their relations with indicators. Structural equation modeling (SEM) is the primary approach for this purpose. In SEM, three types of constructs are distinguished: latent variables, causal-formative constructs, and composites. To estimate the parameters of the different models, various estimators have been developed. Many M…

Returned via Delta to LGA tonight. Totally empty. Fortunately there weren't any jet fuel fumes in the air while we waited 8 minutes for the next M60SBS. Next time someone says they don't see anyone in bike lanes I say LaGuardia airport.
