Study Log
This thread is for anyone studying, learning something new, preparing for any examination, in general; and students in particular.
Use this to share what you are studying and keep track. It'll make you accountable and disciplined.
You could post an update of what you plan to study next week and what you've studied the previous week. Or after one test and before the next one.
I have to study Laplace transform (Math) and KMap upto 5 variables (Digital Electronics) by next week.

Re: Study Log
Are you studying Laplace in the context of an application? I was first introduced in ODE. The idea that you can convert between domains to simplify a problem is fascinating.
Anyway, I'm between semesters now, but I have been reading nietzsche's work (along with several other things). I tend to study about 10 things at once, each not longer than a couple days so this tread might not be for me.

Re: Study Log
Yes. It as a topic in Applied Mathematics3 subject. It is then used as a prerequisite to Circuits and Transmission Lines subject. Both are in the same semester.daylen wrote:Are you studying Laplace in the context of an application? I was first introduced in ODE.

Its application in CTL is for doing
time domain/transient analysis,
for transient voltage or current,
converting time domain functions to frequency domain, heavy side function to unit step signal,
Dirac Delta functifun to impulse signal and
something about ramp signal and
damped response, over, under , critically damped.
Thanks for the revision.
Re: Study Log
Study log.... great idea!
For the past few months I've been plotting to get into the Wilderness First Responder course at our local community college. It is a 4 credit class and is held just once a year so it fills up fast with those who have registration priority at the college. In years past I failed get into the class before it filled so last semester I registered for a Sea Kayaking course which did not get enough participants and was cancelled after two (free kayaking!) classes. That got me into the system and gave me priority over those who were newly registered. This time I logged on within the first hour of open enrollment and secured a spot. With all the fees the total cost was $194. REI offers the same course taught by the same instructor for $750/$785.
A few years ago I went through the EMT program at a different community college and enjoyed it very much so I look forward to this as a refresher that focuses on solving problems far away from the safety net of 911. It should be interesting.
Mrs. Ego will be working on her TESOL certification in the spring.

Re: Study Log
@Stahlmann I recommend you pick up the book "The Elements of Style". This book is a classic on english writing/grammar and is less than $5 on amazon.
Re: Study Log
I am doing an online HTML/CSS course to refresh my web skills. It has been very helpful and I have made a website that I needed that otherwise would have cost $thousands instead of the $20 the course cost. I have all the reference books, but I needed some structured explanation on what is important.
I am also doing a Programming in C course but have slacked on this one. Winter time is a good time to pick this up again.

Re: Study Log
Here's what I'm currently trying to learn (those which I can remember right now)
 Landscape photography (I'm getting better, but practice/doing it can take a lot of time)
 Writing (Improving my writing by blogging)
 Setting up a blog (appearance, layout, general management, SEO, etc.)
 How to gain Instagram followers quickly (ones who are interested in my content).. Currently experimenting with different types and amounts of automation.
 Outdoor survival skills
 Offroad bicycling technical skills
 Automotive maintenance (I haven't made any progress in a long time though,... I really should now)
 Western U.S. history
Some I should pick up, but haven't bothered with for some time:
 Meditation
 Lucid dreaming

I'm using Duolingo to learn an (other) foreign language. So far I have a streak of 49 days I completed at least on lesson.

Re: Study Log
I'm always checking in on Duolingo every now and than to see if they would put up Tagalog (my spouses's language). It would be nice to converse in her language.
Re: Study Log
Bayesian Data Analysis.
For some reason universities teach frequentist statistics so I really had no idea what posteriors, prior, supports and conditional probabilities were.
I got Doing Bayesian Data Analysis; A tutorial with R, JAGS, and STAN and I'm taking the minimalist excursion and then I want to try it on some real life data.
I'm doing all the exercises as I go along. I really want to learn how to DO something, not just have a theoretical understanding of it. I also want to learn something on my own terms for once.
The minimalist excursion (as suggested by the author) is: Chap 19, 1516, 25.1.
That covers intro to book, credibility, models, parameters, The R language, Probability, Bayes Rule, Inferring binomial probabilities, Markov Chain Monte Carlo, JAGS, hierarchial models, generalized linear models, metricpredicted variables on one or two groups, reporting bayesian analysis.
So far I've done chap 15. which is probably close to the first lecture of a Bayes stats course.
Learned so far: priors, updating priors, conditional probabilties, measures of independence, likelihood and support, effect of priors on posteriors, markov representations, dataorder invariance.
Tomorrow: Inferring Binomial Probabilities.

Re: Study Log
Finished chapter and all assigments on exact binomial probabilities using beta distributions and the idea of conjugate priors.
Starting on Markov Chain Monte Carlo methods (Metropolis algorithm and Gibbs sampling).
Every day includes 2 pomodoro study session. And that's it. Just get a little done and mull things over for the next day.
'book I'm writing is now 250 pages. Same as stats: 2 pomodoros every day.

Re: Study Log
@FBHow do you structure the pomodoros? Normally I don't like them (I like to write in long sessions) but my house is hectic at the moment and I'm forced into shorter work sessions. Do you have a trick for jumping back into it? I spend too much time rereading previous work to pick up the mental thread again.
Re: Study Log
There is really not much to structure. I'm alone from 9 to 16 so I have all the time I need to work when I want to.
Pomodors only really work as intended if you can shut EVERYTHING out so if you can't coerce the rest of the household to leave you alone there isn't much you can do about that.
If you can't find a quiet space at home to work, I'd suggest going somewhere else, but I'm also a complete fascist when it comes to a clean and quiet working environment.
I subscribed to Focusatwill.com some time ago and I use their timer to work in Pomodoros. The brainhack music from focusatwill works tremendously well and the builtin timer makes it a nonissue to align the music with my work.
I have all day to compete 4 pomodoros and a normal officeworkday should be somewhere between 8 and 10 so I don't have any suggestions other than: Don't go to work all day and you won't need to work all day

Re: Study Log
Starting on exercises for JAGS (Just Another Gibbs Sampler) which is a semiautomated way of performing MCMC sampling.
I really want to finish this, and then read up on hierarchiel modeling, because the need for Gibbs sampling and the requirements are not that obvious to me. Specifically Gibbs sampling is useful when you have an expression for all the conditional distributions, but do not have an expression for the joint posterior.
So Gibbs is good when you do not have:
P({ t_i }D)
But instead know:
P(t_i {t_j}, D) where j .ne. i
Visually (inside my mind) this is like taking exact slices through the parameter space in one direction at a time, and you are able to do that for all parameters, but so far I can't see the problem where you'd have this exact formulation, and I still somewhat fail to grasp why the Curse of Dimsionality is not a real problem for Gibbs sampling.
When JAGS and hierarchial modeling is done, I'll be taking a look at an introduction to Information Theory.
I am also learning to sleep on the floor, and to live/sit on the floor (Inspired by Katy Bowman's books). So far I really like floor sleeping. Maybe even to the point where I'm not totally keen on getting back in a fluffy bed.
I still need to work on my sitting mobility, mainly because I royally hurt my right leg a few weeks ago. So floor sitting is made somewhat difficult currently.
Sleeping on the floor gets somewhat cold, so I want to figure out how to solve this best. The best solution so far has been to ditch the yoga mat and sleep on a thin fleece blanket and a big yoga blanket instead. I can't figure out why I feel like sleeping with blankets only is warmer that blanket and yoga mat. Still finding resources on floor sleeping, but they are quite far between.
I've slept on the floor for the last 14 or so.
