In the absence of other evidence, isn't it the case that any given trait is 50% heritable and 50% environmental?

Peter Godfrey-Smith discusses this topic at length in his recent-ish book Metazoa and uses observations of insects and other invertebrates to argue, compellingly in my opinion, that sentience and cognitive abilities are not intrinsically

The US put a fission reactor in space too. They did it first, in fact: https://en.wikipedia.org/wiki/SNAP-10A Edit: it’s apparently still there and will be for a long time (!) albeit non-functional: > Decay date

The other pro is cost: cameras are much, much cheaper than LiDAR. Tesla is making the bet that they can close the performance gap between cameras and LiDAR faster than the cost of LiDAR will come down.

Off-topic: in the photo lede at the top of the article, are the rescued merchant mariners wearing standard eye/ear protection or is something else going on? Based on how they are holding the shoulder of the person in front of them, it

I think language acquisition provides a pretty compelling example of learning affecting the experience of qualia. When someone is learning to speak a foreign language, there is often an period where certain sounds are difficult for the lear

David MacKay discusses this in Sustainable Energy Without the Hot Air . He concludes that, while it's on first glance appealing to want to use waste heat from power generation, heat pumps are strictly superior to combined heat and pow

Louis de Broglie's dissertation [1] is mindblowing and quite cogent (at least in the English translation, but presumably in French too ...) 1. https://fondationlouisdebroglie.org/LDB-oeuvres/De_Broglie_K...

Max Welling's Kalman Filter tutorial [1] derives the smoother equations using pretty clear and easy to follow notation (and is a great resource generally). Briefly: you first run the filter equations "forwards", processing ea

That doesn't pose an issue: the "observation model" of a Kalman filer allows for affine transformations (e.g. scale, rotation, and offset) between the sensor data and the "true" latent state that you wish to estimat

By three methods we may learn wisdom: First, by reflection, which is noblest; Second, by imitation, which is easiest; and third by experience, which is the bitterest.

There are many ways to think about the Kalman filter. Here are a few that I like: * You can think of it as a Bayesian update process for linear Gaussian systems. That is: given a prior belief of the state of a system (and an uncertainty abo

That's a bit of a tautology because the population exchange was done on the basis of religion, not language. There were plenty of Greek speaking muslims and Turkish speaking orthodox christians before 1915.

The ground stations tie the satellite network into the internet. Once they have the inter-satellite laser links operational, they will be able to get by with many fewer ground stations.

That's what it means here, too. The idea is that if you take the N-dimensional state-space of neural activity --- each dimension being the activity of a neuron or electrode or voxel or whatever --- and look at how the state evolves thr

This is because of transfer learning: for example, by default, DeepLabCut starts with a pre-trained ResNet-50. Thus these trackers start out with an excellent "understanding" of the statistics of natural scenes out of the box.
