finin | 4 years ago | on: Enigma: GPT-2 trained on 10K Nature Papers: Can you spot the difference?

We've done recent work on using a transformer to generate fake cyber threat intelligence (CTI) and found that a set of cybersecurity experts could not reliably distinguish the fake CTI examples from real ones.

I've found the when teaching, I sometimes work on an example program too much, producing what I think is elegant and compact code, but that the students find hard to understand. I suspect that the same may be true when I am collaborating with others on a program. There can be value in writing code in a straightforward, easy to comprehend style.

I took his AI class, 6.258, 45 years ago, in the Spring of 1971. It was probably the first or second time he taught it. He's a great teacher and inspired me to focus on AI. One aspect I remember was that our exams were all take home exams that we had several days to work on. They were great learning experiences.

The current service returns a ranked (with scores) list of up to 200 entities. You can specify a type in your query or filter the results to select types of interest (e.g., Person, Place or Organization). The top result for 'apple' is the Corporation 'Apple, Inc.' and #2 is Thing 'apple' (a fruit). The score is probably based on a graph popularity metric (e.g., number of inlinks) possibly augmented by pagerank. Interestingly, the knowledge graph ID is the same as the Freebase MID and the results for the KG search for 'apple' appear to be a subset of a similar Freebase search and also in the same order.

I recall DEC's TOPS10 operating system for the PDP-10 using three character extensions. It was introduced in 1970. I think the older PDP6 and ITS systems at MIT-AI had a different scheme for extensions. On ITS I recall that a file had a name and a version number and you could get the most recent version of the file named FOO by referring to it as "FOO >". Every time you edited FOO, you created a new version whose extension was incremented by one. Periodically you issued a command that deleted all of the old versions.

IIRC I first saw the three-letter extension scheme when I started using TOPS10 in 1974.

Yes, the lisp machnes used CRTs, but they did not look like the classic terminals from that era. IIRC they had much higher resolution and were black and white.
