Tasks for the day

- rdconverter
- + convert WaghaeuselFlowChief data
  - ***** fix problem with header, which was added between 2 merged files
    - at the moment “fix” is not to merge files ⇒ clarify with Hr.Lieb ⇒ fix it!
      - decided still not to fix it, because the problem is:
        
        data is not “good”: a file can contain a header, but do not contain it always
  - ***** convert again
  - ***** check
  - + write project docs
  - + commit
- - write a “User Guide” for rdconverter
- - make a small “Project Developer Guide”
- - Clean up
  - - nuertingen
    - - use “data/in” as input directory
    - - use “vars” directory for configs
  - - nagold
    - - use “data/in” as input directory (make use of recursion!)
    - - check what can be done additionally
- - extend documentation
  - - CsvPreprocessor

- datachecker
- - implement SinglePointOutliersCleaner
  - - implement slope detection on multiple points
- - implement MultiPointOutliersCleaner
  - - define TODO
    - - mark as “between slopes”
    - - replace with previous valid value
      - - save previous valid value
      - - fetch previous valid value
      - - replace current value with previous valid value
  - - implement
    - using UDAF?
      - https://medium.com/@suffyan.asad1/user-defined-aggregate-functions-udafs-in-apache-spark-ba373183cbc1
    - using caching machanisms
      - https://stackoverflow.com/questions/36305422/caching-in-spark
- - refactor GetSlopeFromOneRowUDF
  - - move maxAllowedSlope member to MarkSlopeFromOneRowUDF class
- - make a Transformer for “Blockdistanz” (see “1.2 Blockdistanz / Einstau Sonde”)
  - - implement HadSlopeMarkerTransformer
    - - check in current implementation
    - - implement MarkAsBetweenNegativeSlopeStartAndPositiveSlopeEndUDF
      - - test
        
        - test with data of one year
        
        - tests with real data
    - - clean up in HadSlopeMarkerTransformer and in all UDFs used there
      - - simplify getting/marking slopes using only
        
        SLOPE_TO_PREVIOUS_COLUMN_NAME_DEFAULT
        
        ⇒ getSlopeToPrevious using GetSlopeFromOneRowUDF()
        
        SLOPE_TO_NEXT_COLUMN_NAME_DEFAULT
        
        ⇒ getSlopeToNext using GetSlopeFromOneRowUDF()
  - - implement SlopeBasedBlankingDistanceDataTransformer
    - - implement ReplaceValuesWithinEntlastungEventUDF properly
      - ??? use gradient (as first solution) ⇒ GradientBasedBlankingDistanceDataTransformer
        
        (⇒ it should be not necessary because it is already calculated in HadSlopeMarkerTransformer.BETWEEN_NEGATIVE_SLOPE_START_AND_POSITIVE_SLOPE_END_MARKER_COLUMN_NAME_DEFAULT)
        
        ??? check how gradient can be calculated
        
        proposal 1:
        
        if (start point is near of the maxValue)
        
        if(t2-t1 < X min)
        
        if(slope > 0 && slope > maxSlope)
        
        ⇒ mark as “probableBlockingDistance”
        
        proposal 2 (older?):
        
        if (start point is near of the maxValue)
        
        if(there was a slope with “speed” ⇐ maxSpeed)
  - - define scenarios
    - Scenario 1. (simple)
      - runter und nach einer Weile wieder hoch
        
        Beispiel: Bild 1, zweite Lücke
    - Scenario 2.
      - runter, dann hoch, aber nicht bis zum Anschlag, dann ein paar mal hoch und runter, aber jedes Mal nicht bis zum Anschlag und nur ziemlich später wieder hoch bis zum Anschlag
        
        Beispiel: Bild 1, erste Lücke
    - Scenario 3
      - runter, dann relativ stabil, dann aber noch stark nach unten
        
        Besipel: Bild 3
    - Scenario 4
      - ask Benjamin
        
        letztes Bild im Abschnitt 1.2, letzte Lücke
        
        es ist unklar wie die rechte Seite von der Lücke korrigiert wurde
  - - test all defined scenarios
- - optimize building
  - set jar to “target” of sparktest
- - create a new project for transformers
- - test “1.1. Einfache Ausreißer”
  - test data is in /home/vkalaschnikow/Desktop/buero/Entwicklung/Plausibilitätsprogramm/Beispiele Messfehler Datenlücken
- - implement a graph for our data
  - - find out which graph libs exist
  - - decide how to handle “big data problem”
    - - find out which solutions exist
    - - implement 2-3 options
- - “data gaps analysis” → SparkTester.getStatsAboutMultipleIntervals()
  - - test Apache Zeppelin
    - - build zeppelin from IntelliJ
    - - Writing visualizations:
      - https://zeppelin.apache.org/docs/0.11.0/development/helium/writing_visualization_basic.html
