Alexis C. Madrigal on how Janelle Shane set machine learning to work on existing knitting patterns to create new ones:Ai machinelearning knitting
<p>here’s the first 4 rows from one set of instructions that the neural net generated and named “fishcock.”
row 1 (rs): *k3, k2tog, [yo] twice, ssk, repeat from * to last st, k1.
row 2: p1, *p2tog, yo, p2, repeat from * to last st, k1.
row 3: *[p1, k1] twice, repeat from * to last st, p1.
row 4: *p2, k1, p3, k1, repeat from * to last 2 sts, p2.
The network was able to deduce the concept of numbered rows, solely from the texts basically being composed of rows. The system was able to produce patterns that were just on the edge of knittability. But they required substantial “debugging,” as Shane put it.
One user, bevbh, described some of the errors as like “code that won’t compile.” For example, bevbh gave this scenario: “If you are knitting along and have 30 stitches in the row and the next row only gives you instructions for 25 stitches, you have to improvise what to do with your remaining five stitches.”
But many of the instructions that were generated were flawed in complicated ways. They required the test knitters to apply a lot of human skill and intelligence. For example, here is the user BellaG, narrating her interpretation of the fishcock instructions, which I would say is just on the edge of understandability, if you’re not a knitter:
“There’s not a number of stitches that will work for all rows, so I started with 15 (the repeat done twice, plus the end stitch). Rows two, four, five, and seven didn’t have enough stitches, so I just worked the pattern until I got to the end stitch and worked that as written,” she posted to the forum. “Double yarn-overs can’t be just knit or just purled on the recovery rows; you have to knit one and purl the other, so I did that when I got to the double yarn-overs on rows two and six."
