You get home after a full day of work, tired. You gather some of the basic ingredients for the classic negroni but, instead of regular gin, you get a jar with beets and gin that you prepared in the morning when you knew that your arrival from work later that day would beg for a beet negroni.

You put all the ingredients in a shaker.

You close it, and shake well. Then you grab a cold martini glass from the freezer and throw in an orange peel. (Not everyone likes their negronis served this way, I know).

Any glass would do, but I prefer these.

You serve it, and enjoy.

Now for the backstory: a few days ago I read that Parm, a restaurant in New York city, is making beet negronis. Given my love for both things, I decided to give it a try without a recipe. If anyone knows the actual recipe, please share. Meanwhile, I will enjoy this drink…

During the past few days I have been reviewing applications of students and researchers interested in working or studying in our department. The quality of the average application in the pool is impressive.

I don’t know how much this may be due to the economy, the overall higher education levels in developing countries, the popularity of our department and/or our field, etc. Whatever the causes, the fact is that some applications are off the charts, and this has made me start thinking.

To start, I wonder if my application would have been accepted if I were submitting it along with the ones that I am seeing today. Probably not. Secondly, I wonder how accurately does the information in these applications represent the qualities of the applicant and his/her ability to succeed in this environment. There is only so much that can be communicated through these forms and papers.

But perhaps more interestingly, what seeing all these strong applications makes me feel is a bit jealous. Not in a bad way, but still, jealous. Jealous and a bit melancholic.

You see, I left my country five and a half years ago driven entirely by an insatiable thirst for scientific/engineering knowledge. The four years I spent studying here allowed me to reinvent myself and branch far out of what a typical person with a degree in Civil Engineering from the DR would be able to do. I learned a good number of really useful concepts, techniques, algorithms. My time was spent mostly feeding my brain new knowledge, and playing around with it afterwards: bliss.

But the time to do these things with such dedication is probably behind me already. As a tenure-track faculty there is less time for Mario the learner, because Mario the manager needs to come to existence. A good part of my job today is to ensure that others can effectively go through the steps that got me here and, although there is still a good deal of learning to do, it does not seem likely that I will ever be able to, for instance, become an expert in functional analysis or nonparametric bayesian methods, to name a few examples.

Who knows? Maybe I will. Regardless, I will still reminisce on how great it was to be a graduate student, with no other responsibility than becoming an expert, like a child…. like a child.

When I started writing this post, I was sitting on a train from Granada to Madrid. I had spent the last two days in Sierra Nevada, a National Park in Spain known for its great ski slopes. The Neural Information Processing Systems (NIPS) conference for 2011 had its workshops there in December, and I was an invited speaker for the “Machine Learning for Sustainability” workshop. I had a good time there, and look forward to attending this year too.

During the 40 hours that I was in Sierra Nevada (yes, unfortunately it was a short trip), there were talks on many different topics, which was very refreshing for me. Besides talks focusing on energy, the topic I work on, there were talks on global climate models, ecosystem modeling, species conservation and water monitoring. Overall, it was a well organized event that shows promise.

At the end of the day, it seemed as if there were basically two main things that could be improved for next year’s version of the workshop: (a) better advertisement and (b) clearly define a few interesting problems in sustainability along with the challenges they pose to the machine learning (ML) domain, so that more people from the ML community can join in.

The first issue I am battling by writing about the workshop here. I will attempt to address the second issue by summarizing my talk on another post later. I spoke about “Machine Learning Challenges in Building Energy Management”. For now, however, I will leave you with some pictures of Sierra Nevada and La Alhambra, as well as with the following thought: are the carbon emissions associated with a transatlantic flight to a sustainability conference in any way less harmful? A positive answer would help me feel better about myself.

There are four links to share with you for the past two weeks. One of the more interesting ones is this detailed study on flavor networks:

Last year, after starting the job as a faculty member, I decided to analyze my e-mail usage up to that point and discovered that there had been a sharp increase in the number of e-mails sent/received immediately after I started the new job.

I had the impression that things had only escalated since that time so, to continue with the tradition, I decided to run the same analysis this year. The results are in some ways expected: the number of e-mail exchanges has continued to increase. The only difference, though, is that I now feel as if I have almost reached the limits of my ability to process and respond to this flood of e-mails in a timely manner. I have adopted quite a few changes and improved my GMail ninja skills, but this can only take me so far. Who knows what will happen next year…

First, here is the graph with total number of e-mail exchanges per year since 2005:

Annual number of e-mail exchanges

And here is the month-by-month graph for 2011, as of 12/12 when I generated this graph:

Monthly numbers for 2011

Monthly numbers for 2011

Lastly, here is the daily numbers for November 2011:

Daily numbers for November 2011

Daily numbers for November 2011

Let’s hope for a better year, with less e-mail!

All these graphs were created using a nifty piece of python code called mail-trends.

It’s funny how effective a promise to myself can be. I promised to write every day of the month of November (starting on the 7th), and I did. But after that I have written very little here.

Anyway, here are the links for the week that just passed:

There is something very powerful about this house that Frank Lloyd Wright designed. Every time I visit (and this must be the 4th or 5th time) I leave with a long-lasting impression and a feeling of awe and peacefulness like the one that follows after watching a good movie or experiencing a great painting.


Pictures cannot describe what it feels like to experience that house. One enters the gates to the property and slowly but surely, the walk to, into and out of the house transforms into a conversation between your body and the surroundings, a hushed dialogue that lingers for days.

Links (27/November/2011)

November 27, 2011

I have been posting these links of the week for about three years, always in Spanish. Let’s switch to English for a change. Being a big fan of To-Do lists, the link I would like to feature is an an article at an NPR science blog that talks about an upcoming book about Leonardo DaVinci. [...]

Cinemascapes

November 24, 2011

Photographer Aaron Hobson carefully selected Google Street View shots and added them to his Cinemascapes collection, in which he explores “close quarter panoramics, open ended narratives”. From what I can tell these are actual Google Street View images, but I could not find a link to the original, hosted on Google. Either way, they look [...]

Puzzle

November 22, 2011

Before going to sleep, I decided to open a deck of cards with math puzzles that I keep in the living room. Here are two of the puzzles that will have to wait until tomorrow when my brain is recovered from 13 hours of work: What number should replace the question mark? a. 6, 8, [...]
