  • Finished installing tensorflow for all user. Create a new folder to work on the DBServer to use tensorflow. The folder can be found here:
Z:\AcceleratorDemoDay

or if accessed from PuTtY, use the following command:

cd \bulk\AcceleratorDemoDay
  • The new RNN currently has words frequency as input features

/usr/local/cuda-9.0 

for the toolkit. Did NOT install NVDIA accelerated Graphics Driver for Linux-x86_64 384.81 (We believe we have a different graphic driver. we have a much Newer version(396.26)). Installed the CUDA 9.0 samples in

HOME/MCNAIR/CUDA-SAMPLES.
  • 2. Installed Patch 1, 2 and 3. The command to install was
sudo sh cuda 9.0.176.2 linux.run # (9.0.176.1 for patch 1 and 9.0.176.3 for patch 3)
  • 3. This was supposed to be what to do next:

""" Set up the environment variables: The PATH variable needs to include /usr/local/cuda-9.0/bin To add this path to the PATH variable:

$ export PATH=/usr/local/cuda-9.0/bin${PATH:+:${PATH}}

In addition, when using the runfile installation method, the LD_LIBRARY_PATH variable needs to contain /usr/local/cuda-9.0/lib64 on a 64-bit system To change the environment variables for 64-bit operating systems:

$ export LD_LIBRARY_PATH=/usr/local/cuda-9.2/lib64\${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

Note that the above paths change when using a custom install path with the runfile installation method. """ But when we travel to /usr/local/ we saw cuda-9.2 which we did not install. So we are WAITING for Yang to get back to use so we can proceed.

  • For now, I can't build anything without tensorflow, so I am going to continue classifying data.
  • Helped Grace with Google Scholar Crawler's regex
  • All installationote can be see here Installing TensorFlow

2018-07-11:

  • With an extended dataset, the accuracy went down with the random forest model. Accuracy: 0.71 (+/- 0.15)
  • Built codes for an RNN, running into problem of not having tensorflow installed
  • Helped Grace with her Google Scholar Crawler.
  • Asked Wei to help with installing tensorflow GPU version.

2018-07-10:

  • Doing further research into how RNN can be used to classify
  • Reorganize the code under a new folder "Experiment" to prepare for testing with a new RNN
  • Ran the reorganized code to make sure there is no problem. I kept running into this error: "TypeError: ufunc 'isfinite' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule safe"
  • Apparently this was caused by random question marks I have in the column (??) Removed it and it seems to run fine.

2018-07-09:

  • Continued studying machine learning models.
  • Helped Grace with her LinkedIn Crawler.
  • Cleaned up working folder.
  • Populate the project page with some information.

2018-07-06:

  • Review Augi's classified training data to make sure it meets the correct requirement.
  • Continued studying machine learning models and neural nets

2018-07-05:

  • Studied different machine learning models and different classifier algorithms to prepare to build the RNN.
  • Worked on classifying more training data.

2018-07-03:

  • Ran a 0.84 classifier on the newly crawled data from the Chrome driver. From observation, the data still was not good enough. I will started building the RNN
  • Still waiting Augi to release lock on the new excel data so i can work on it.

2018-07-02:

  • Why did the code not run while I logged out of RDP omg these codes were running for so 3 hours last time I logged off :(
  • The accuracy got to 0.875 today with just the new improved word list, which I thought might have overfitted the data. This was also rare because I never got it again
  • Ran the improved crawler again to see how it went. (The ran start at 10AM ~It has been 5 hours-ish and it only processes the 50% of the list)
  • After painfully seeing firefox crawling (literally) through webpages, I had installed the chromedriver in the working folder and changed the DemoDayCrawler.py back to Chrome Webdriver
  • It seems like Firefox has a tendancy to pause randomly when i don't log into rdp and keep an eye on it. Chrome resolves this problem

2018-06-29:

  • Delegated Augi to work on building the training data.
  • Started to work on the classifier by studying machine learning models
  • Edited words.txt with new words and remove words that i don't think help with the classification. Removed: march/ Added: rundown, list, mentors, overview, graduating, company, founders, autumn.
  • The new words.txt had increased the accuracy from 0.76 to 0.83 in the first run
  • The accuracy really fluctuated. Got as low as 0.74 but the highest run has been 0.866
  • Note: testing inside of KyranGoogleClassifier instead of the main folder because the main folder was testing out the new improved crawler.
  • It also seemed that rundown and autumn is the least important with 0.0 score so I removed them

2018-06-28:

  • Continued to find more ways to optimize the crawler: adding several constraints as well as blacklist websites like Eventbrite, LinkedIn and Twitter. Needed to figure out a way to bypass Eventbrite's time expire script. LinkedIn required login before seeing details. Twitter's post was too short and frankly distracting.
  • Ran improved results on the classifier.
  • Classified some training data.
  • Helped Grace debug the LinkedIn Crawler.

2018-06-27:

  • Worked on optimizing and fixing issues with the crawler.
  • It was observed that we may not need to change our criteria for the demo day pages. The page containing cohort list often includes dates (which is a data we now need to find). I might add more words to the words bag to improve it further but it seems unnecessary for now

2018-06-26:

  • Finished running the Analysis code (for some reasons the shell didn't run after i logged off of RDP
  • Talked to Ed about where to head with the code
  • Connected the 2 projects together: got rid of Kyran's crawler and Peter's analysis script for now (we might want the analysis code later on to see how good the crawler was)
  • Ran on the list of accelerators Connor gave me. Got mixed results (probably because the 80% is low) and we had to deal with website with expire timestamp like Eventbrite (the html showed the list, but displaying the html in the web browser doesn't). Found a problem that the crawler only get the number of results of the first page so if we want to gather large numbers of result, it would not work.

2018-06-25:

  • Fixed Peter's Parser's compatibility issue with Python3. All code can now be used with Python 3
  • Ran through everything in the Parser on a small test set.
  • Completed moving all the files.
  • Ran the Parser on the entire list.
  • The run took 3h45m to execute the crawling (not counting the other steps) with 5 results per accelerators
  • Update @6:00PM The Analysis has been taking an hour and 30m to run and only 80% done. I need to go home now but these steps are taking a lot of time

2018-06-22:

  • Moved Peter's Parser into my project folder. Details can be read under the folder "E:\McNair\Projects\Accelerator Demo Day\Notes. READ THIS FIRST\movelog".
  • The current Selenium version and Chrome seem to hate each other on the RDP (throwing a bunch of errors on registry key), so I had to switch to a Firefox webdriver. Adjusting code and inserting a bunch of sleep statements.
  • For some reason (yet to be understood) if I save HTML pages with the utf-8 encoding, it will get mad at me. So commented that out for now.
  • The code seemed slow compared to those existed in Kyran's project. Might attempt to optimize and parallelize it?
  • it seems that python 3 does not support write(stuff).encoding('utf-8')?

2018-06-21:

  • Continued reading through past projects (it's so disorganized...)
  • Moved Kyran's Google Classifier to my project folder. Details can be read under the folder "Notes. READ THIS FIRST\movelog".
  • Tried running the Classifier from a new folder. The Shell crashed once on the web_demo_feature.py
  • Ran through everything in the Classfier. Things seemed to be functioning with occasional error messages
  • Talked to Kyran about the project and clarified some confusions up
  • Made a to-do list in the general note file ("Notes. READ THIS FIRST\NotesAndTasks.txt")

2018-06-20:

  • Set up Work Log page.
  • Edited Profile page with more information.
  • Created project page: Accelerator Demo Day.
  • Made new project folder at E:\McNair\Projects\Accelerator Demo Day.
  • Read through old projects and started copying scripts over as well as cleaned things up.
  • Created movelog.txt to track these moving details.
  • Talked to Ed more about the project goals and purposes

2018-06-19: More SQL. Talked to Ed and received my project (Demo Day Crawler).

2018-06-18: Set up RDPs, Slacks, Profile page and learned about SQL.
