Thanksgiving ingredient network leftovers

Filed under: data, statistics, visualization,papers — Tags: , , — ladamic @ 03:29

Michaeleen Doucleff just wrote a very fun article on our recipe network paper for NPR’s the Salt.

It made me realize that Edwin Teng, Yuru Lin and I have some leftover plots that may be Thanksgiving appropriate. If you don’t have quite the right ingredients handy while cooking Thanksgiving dinner, here is a network of common substitutions as found in reviewers’ comments on a large recipe site (click to see a larger view):

The favorite Thanksgiving ingredients are often recommended as substitutes. e.g. cranberries end up substituting for other kinds of fruits and even somehow for chocolate. In the fat category, olive oil and butter seem to be recommended as substitutes for things such as margarine. Yams are often recommended as a substitute for sweet potatoes (more so than the other way around), etc.

Recently, from my Coursera class, I created region specific networks using data shared by YY Ahn & co. in their flavor network paper. This isn’t a complete set of all regions, but see if you can guess which region is visualized in each of these (mouse over for the answer, your choices are Northern European, Southern European, North American, Latin American, Middle Eastern, South Asian, African, Southeast Asian, East Asian):

 

Lastly, and most deliciously, here is the network of complementary ingredients for Thanksgiving, created by my collaborator Edwin Teng:

Bon Apetit!

Social media and the ex

Filed under: random musings — ladamic @ 06:58

My past relationships predate social media of the Friendster and later type. So being friended or circled or followed by an ex on social media can’t be a case of ‘Oops, forgot to unfriend/uncircle/unfollow’. But these connections do pique my interest, not because there’s anything much to say, but because there might be interesting news & quirky thoughts to follow. After all, if I can be curious about gossip regarding celebrities from shows I don’t even watch, this is bound to be more interesting. Did I just admit to reading a gossip blog? (BTW, if you’d be interested in creating a Gossipedia, please let me know. If anything needs to be compiled and sources identified, then its gossip.).

Connections that ended almost as soon as they started are both odd and well-suited candidates for something as light and feathery as Twitter.

Loving an unloved romance film

Filed under: Uncategorized — ladamic @ 13:01

Tristan and Isolde was director Kevin Reynolds’ last movie to see theatrical release. Screenwriter Dean Georgaris never had another screenplay turned into a feature film. Producer Ridley Scott seemed to have distanced himself from it even as it was being filmed. It was the last film Franchise Pictures distributed before going bankrupt. James Franco, the male lead, regretted it so much, he bothered to write it up as his favorite mistake, 7 years later.

I saw it by chance (chance engineered by Amazon.com). I had wanted to re-watch ‘Elizabeth’ in the earlier days of Netflix and Amazon Video, when neither had it. But Amazon resourcefully recommended Tristan and Isolde. I watched it. I thought ‘huh’. But then a few months later I watched it again, and thought it brilliant. Unfortunately, any friends I have managed to get to see it share only my initial reaction of ‘huh’.

After becoming a bit obsessed with T&I, I bought the DVD, not so much because I needed the physical DVD, but because I was hoping to express gratitude and in a miniscule way boost global sales. I was also hoping that the extra features would show that the cast and crew appreciated the brilliance of the movie even if the film critics had failed to do so (it was 32% fresh on Rotten Tomatoes). But all the interviews contained were repeated complaints about an extremely tight budget, frigid water, and gnats.

My last hope was Georgaris, the screenwriter. After all, even though to my untrained eyes and ears the film looked and sounded great, it was the intricately woven plot and the sparing and intriguing dialogue that surely made the movie. Alas, all Georgaris had to say was that he was originally thinking of setting it in space, and that an earlier draft was deemed too cheesy by a friend.

It’s not my favorite realistic romance (that goes to Before Sunrise + Before Sunset), but it’s my favorite unrealistic romance. Not that I know all that much about the genre (for example, I’ve never seen Titanic and can count on 1 hand the number of romance novels — all horrible — I’ve attempted to read). The weird early-teen magic-potion suicide mix-up of Romeo and Juliet never much made sense to me, and neither did Wuthering Heights (even the house-remodel in the Notebook seemed a bit strange).

I won’t spoil the movie by giving away to much, just in case you are looking for that ‘huh’ experience. What separates this movie from others (besides the awesome screenplay) is having a male romantic lead who is brawny, brainy, and loyal to a cause/person (and gets to show this off during the movie). But unlike other hero-focused movies where the romance subplot is intended as another opportunity for the hero to overcome a challenge (e.g. by rescuing the girl), Tristan doesn’t rescue Isolde (at least not intentionally), but instead she saves his life. Maybe I read too much Prince Valiant as a kid, but what other movie has a valiant knight in an interesting romantic entanglement? You’d think there would be scores of these, but… And so I join scores of Amazon and imdb users in adoring a movie that is unloved by its makers and critics.

Keynote

Filed under: conferences/workshops,random musings — ladamic @ 16:32

This year I had the great honor of giving one of the keynote talks at the ICWSM conference, a conference I had been attending and enjoying for years. I ended up delivering the keynote on 4 hours of sleep, despite 10 months lead time to prep the talk. I don’t know how to explain it, except:

Lada channeling James Franco in photo op.Lada channeling James Franco in photo op.

Which is how a squinty photo of me (along with perfectly well-rested looking John Breslin, Igor Perisic, and Jimi Shanahan) ended up in the Irish Times.

Lada channeling James Franco in photo op.

I’d like to think I was just channeling James Franco, who always looks a bit squinty, because he is too awesomely busy to get any sleep.

Superwomen

Filed under: Uncategorized — ladamic @ 13:06

Everyone’s read the Anne-Marie Slaughter piece in the Atlantic on why there are so few women on the upper rungs of government and corporate ladders. Most of the discussion of the piece I’ve seen is about work/life balance, etc., but what resonated with me is Prof. Slaughter’s insight that the women we aspire to be (Hillary Clinton, Sheryl Sandberg, etc.), and who advise us that we can have it all, are superwomen. I agree, except that I think we don’t have to look at the upper rungs to find them. I run into them all the time. And here are my observations from the field:

While the rest of the world sleeps soundly, the superwoman steadily advances science.

Late into the night:

It's 11pm, do you know where your stack of work is?

or the wee hours of the morning.

When even the squirrels are still sleeping.

If she has volunteered for an especially critical task, the superwoman does what must be done:

If she is deprived of sleep for another reason, well, that’s just another opportunity for the superwoman to advance science:

Unlike the rest of us, the superwoman does not need to catch up on sleep. The superwoman never naps…  well, almost never.

And when duty calls for her to save another part of the world, the superwoman flies back on the weekends to take care of her responsibilities back home.

To the superwomen out there: you’re all my heroes. And to the supermen, you have my admiration as well!

A while ago I commented on how I haven’t practiced dressing up too much. Apparently Visa’s fraud detection algorithms have detected this.

the “Nature” paper

Filed under: random musings — ladamic @ 20:34

[By ‘you’ I mean me, but it’s easier to say ‘you’] You spend sleepless nights and frustrating days working on a problem, pushing the limits of your data-analysis, algorithmic and analytical know-how, following obscure and not-so-obscure leads through the literature,  until, one day, it clicks. Your model actually fits the data. And no one has even seen data like this before. You’ve made a scientific discovery!

eurekaA colleague who hears you gushing about the result suggests you submit it to Nature. Although you have only written up bits and pieces during the course of the research, it’s too late now, those bits have become the “Nature” paper.

Even in this incomplete state, the “Nature” paper changes you. It makes you feel important, special. You go to conferences and are surprised to find that a lot of other researchers have “Nature” papers.

conferenceAfter a bit of initial angst that they may actually have your “Nature” paper, you wonder a) if Nature will have enough room and b) if these people seem a bit delusional, am I delusional too?

As you spend weeks to months doing the last 10% of the work to make the paper 100% ready for submission, you try to handle the anxiety of getting scooped. Mornings are the worst, as you read arxiv or Google News headlines (because of course, any paper that did what your “Nature” paper does would capture the headlines).

checking newsUntil one day it happens. Your office mate has spotted a Nature (no quotes) paper on X, and your “Nature” paper is on X. Your stomach turns, you quickly skim the paper. Relief: the paper says X, it’s not your X.

scooped

After that scare, your work pace gets even crazier. Gotta finish that last 1%, triple-check all results. You send the paper to a few people who regularly publish in Nature. When they say they like it, you’re over the moon. And if they ask where it’s going to, you reluctantly admit your aspirations.

where are you submitting to?When you’re not working, you daydream. You imagine your PhD advisor, mom, dad, long-ago flame just happening to read your paper, because they all read Nature or at least used to or at least used to say they do.

who is readingYou’ve delayed as long as possible, but it is time to do the final formatting. You create a new folder, and give it a name e.g. “Nature2012” which will forever serve as a painful reminder of your unsuccessful attempt if the paper is rejected.

the folderNow you are ready to begin formatting. Inexplicably, you are asked to take your perfectly well-formatted paper, tear out the figures, upload them as separate files (which you will have to rename, resize, and resort), separate out the figure captions (to ensure that the reviewers will have the most difficult time figuring out what you are talking about when referring to a figure), and then wait for the submission system to glue them back together in the most impractical and unreadable form possible. This will take hours to days.

formatting the submissionFinally, you submit. It’s a strange feeling. The creation you have labored so hard for is now in someone else’s hands. There is emptiness. You start to think about other things in life besides the “Nature” paper. Life returns to “normal”. Then…

rejection

Rear Window

Filed under: random musings — ladamic @ 05:48

I have been puzzled by the styling of new cars in the past few years, which appears to shrink rear passenger windows.

Take for example this 2012 car (Kia Rio), relative to its 2008 version (which already has a smallish rear passenger window).

Perhaps the styling around the side view mirror is playing visual tricks on me and there hasn’t been much change 2008-2012. However, one thing I’m sure about is that the 1991 Honda Civic (arguably the best car ever designed and built), is positively an aquarium relative to the newer models.

I can think of 2 reasons for this development: fashion and safety. I sincerely hope it is fashion, because fashions come and go, but boring safety is always there to stay. And in this case it really is boring. A small boy who loves cars, trucks, and buses, but rides in a newer model car, only has a chance to see the occasional airplane or tree/bus/truck tops.

Reading to distraction

Filed under: Uncategorized — ladamic @ 04:51

On a recent visit to NYU I accidentally activated an alarm by exiting through the wrong door. As I sheepishly retraced my steps back toward the security guard, he admonished me ‘Didn’t you read the sign on the door?’. Actually, I try very hard not to read signs. That little voice in my head likes to read them to me. In my undergrad house at Caltech, I’d sometimes get up from working on a problem set to go to the restroom: ‘I wonder if I approximated the functio… “PLEASE PROP DOOR OPEN WHEN NOT IN USE” .. uh… what was I thinking?’. I tried to move the sign or dispose of it altogether, but it would reappear in the same spot shortly.

Recently my attempts to think on the way to and from lunch have been foiled by the brilliant “Thanks to Berkeley” campaign. As I walk down Berkeley’s shady paths, I’m greeted by smiling faces telling me all that they can do thanks to their fine university. Staring at the ground is a pity in such pretty surroundings, but it did pay off recently when I had to step over someone sprawled in the middle of the path, possibly protesting something, possibly not.

Perhaps my most pathetic repeat reading is that of art posters specifying the artist and the exhibit featuring the work, e.g.:

There are studies recording a higher incidence of traffic accidents within viewing distance of attention-grabbing billboards. But who is keeping track of the many small crashes our brains experience when exposed to reading material?

Girls who like boys they want to be like

How many of us can trace some interest, hobby, or even career choice to a youthful infatuation?

I encountered Ivan in my grandmother’s kitchen in Split. He had requested an extra strong shot of Cedevita (a powdered vitamin drink), and my aunt obliged by filling the glass half-full with powder. He brushed his floppy hair aside, downed the fizzy concoction, grimaced, and laughed. That vacation he rang the doorbell a few more times, while I sat around writing poems about him and how I wished the doorbell would ring. On the one visit to his apartment in the building next door, he showed me a fantastic self-portrait he had painted, and some exercises he was doing in art school. He was 14. I was 12.

The following year I was again in Split, but just for an evening. Ivan and I wandered around the old city, eating corn on the cob bought from a street vendor. Ivan was so funny, I nearly peed my pants. Maybe I even did pee my pants. When we got back, I dug up the poetry I had written for him. He listened, amused, and when I walked him to the door, he leaned in for a kiss. I momentarily panicked and closed the door in his face, which was the last I ever saw of it. He and his mom moved the next year, possibly related to the collapse of their 2nd floor balcony on New Year’s Eve, when everyone had piled out onto it to watch the fireworks.

The reason I mention Ivan is that he nearly made an artist out of me. Not only did I increase my Cedevita intake,  but I started painting in earnest. Every once in a while, I would pull out a photo of Ivan’s self-portrait for inspiration. In the following 1.5 years I painted enough for a small portfolio that gained me admission to 2 art magnet high schools in NYC. I opted for Stuyvesant HS instead, and pretty much abandoned my interest in art for a while. But it was a close call. Ivan went on to become a professional illustrator and published a graphical novel (as Google tells me).

At Stuyvesant I became infatuated with M., who sat in the row behind me in biology class. I almost never talked to M., except to catch him saying “I play violin” (I purchased several violin concertos on CD, lacking any discernible music ability of my own), “I run track” (I joined the track team, even though gym was my worst subject), “I go to ancient greek club in the morning” (this I only tried a few times because at 8am it conflicted with math team), “now I play the cello” (I augmented my CD collection to include cello compositions). Our biology teacher must have noticed my obvious crush, and paired us off for a quiz on human sexuality. M. knew all the answers, except one; I switched his answer of “semen” to “seminal fluid”. We got a 100 on the quiz, but that was just about the only success I experienced with M. (besides when we compared our 1st report cards and he said “What? Your GPA is 98.7? I though my 98.1 was the highest!”).

At the end of freshman year, my family moved. M. stayed. Although I don’t remember any ancient greek at all, I did gain a greater appreciation of string-oriented classical music, and I actually continued to run track and cross country for the rest of high school in an undistinguished way. M. continued his musical training and plays concerts, but is a physician by day (um, thanks again Google).

I suppose that must be what they mean by “impressionable” when they talk about youth. I wasn’t sure who I wanted to be. Liking boys, and then wanting be like them, made sense. But once I knew who I wanted to be, who did I want them to be? By the time I was a freshman at Caltech, I wanted to be a physicist, or a mathematician, or something like that. E., a sophomore physics major and my first steady boyfriend, was acing his classes. I thought he was great, and so did he. When a few short months later, he dumped me for another, I started dating D., who had published papers already back in high school. D. was a more attentive boyfriend than E., e.g. on the occasion of breaking up with me, he told me a couple of jokes to cheer me up first.

Even before their ends, these relationships made me unhappy. Dating conspicuous academic accomplishment comes at a price. Not only did I have to compete with E and D’s homework /extra credit/research assignments for their attention, but it spoiled my independent fun to know that my significant other had the discipline to work all the time while I sometimes wanted to not work. It was also difficult to maintain self-esteem. While constantly thinking about how great they were, I couldn’t help but notice that I wasn’t as great. When my freshman progress report for a sophomore abstract algebra class generously said that “Lada is getting used to the level of abstraction”, D’s progress report for a graduate level applied math/CS class said that he was far outperforming the graduate students. Even though E and D were always able to help me if I got stuck on homework assignments, my self-esteem and GPA improved after they were no longer around.

So after ceasing to want to be like the boys I liked, I also stopped liking men I wanted to be (exactly) like. Now I’m married to a man I like to love, and who has many fine qualities I can admire without necessarily wanting to acquire.
