I opened PRs for the code pieces which I may not deliver for the university projects.I increased the prediction time from 80 ms to 400–500 ms due to a lack of functional tests.I reduced the model performance by adding simple features that improved the model performance while the model building.I made a lot of estimations, and I extracted too many features without any bias-free baseline study.In addition to this example, we make many mistakes and apply too many dreadful practices. Otherwise, all the academic people with several cited articles or all the startups/companies with over-performing hardware will not fail in the industry. As this example demonstrates, using state-of-the-art technology may not bring value to the companies and their clients. Although the implementation provides a sufficient performance increase, Netflix never used this prize-winner study due to additional costs. In 2009, a developer team implemented a recommendation algorithm that improved the accuracy of the current recommendation system at Netflix by 10% then the team won a Grand Prize. The class that contains the main method is Datathief.I am pretty sure that the majority of you came across the title ‘ Netflix never used its $1 million algorithm’ at least once. If you have problems starting Datathief.jar, the following might help: Do not accept this java requires the file to have the 'jar' extension. Some Windows installations offer to save the Datathief.jar file as Datathief.zip. I shall try to solve the problem, but it seems a tricky little item of what my software does with how Java is implemented for MacOS X. Zooming in and out, or any other way to refresh the screen will do the trick. There is one known problem which I have as yet been unable to solve: On (some versions of) MacOS X, when you load an image, it is not automatiaclly displayed. Try reducing the dimensions of the image. I you get an error message explaining that the program quits due to a "OutOfMemoryError", this usually means that the image you are using is too big. If you have lost your reference locators, you can use the reset menu item to move all locators to their default positions. It is now impossible to move point to the top or the left out of the screen. Under certain circumstances negative numbers in scientific notation were respresented as positive (ouch)! There was a serious bug in the previous versions of DataThief. Made it possible to enter the key using copy and paste Regretfully the fix introduced another bug. The number 1.0001 was formatted as 1.0E-4. There was another bug in the formatting of numbers. The bug that was introduced in version 1.4 was repaired. When you zoom in, the motion will be even more precise. Now you can move the point using the arrow keys on your keyboard. To move a point it is now possible to locate the mouse pointer over the point so the pointer will turn to a crosshair. View the tutorial video Changes in DataThief III version 1.7įixed a nasty little bug that sometimes caused a number to have an exponent of 1 less then it should be. The MD5sum for Datathief.jar is: 2d76e91ab76c5c1b3c59337260ae2956 Datathief.jar The manualĮven though the aim has been to create an easy to use tool, DataThief III has many possibilities that are hard to understand without the manual. Usualy downloading Datathief.jar will work. Java has had a serious security problem with a module called Log4j.ĭataThief does use Java, but this specific module is not included in the DataThief code, so this security problem is not present in DataThief.įor the more curious, a full list of Java modules used in DataThief is here. Please buy the shareware registration key from It can convert data from numeric format to any other format, for instance dates.It is capable of tracing any more or less continuous line, even when the line crosses itself.It is written in Java, it runs on Windows, Unix, Macos.Typically, you scan a graph from a publication, load it into DataThief, and save the resulting coordinates, so you can use them in calculations or graphs that include your own data. Welcome to DataThief What is DataThief IIIĭataThief III is a program to extract (reverse engineer) data points from a graph.
