+# MyClassifier
+So far completed: Sensor-data-gathering prototype
+
+To do: Everything else 
+
+My Classifier
+Android Machine Learning Development Tool
+
+● A tool to help researchers and developers to visualize
+and experiment with classification using phone sensor
+data, all in the same app </ br>
+  ■ Classification: takes a set of features associated
+  with a condition and finds a model that predicts
+  when the condition obtains
+  ■ User chooses condition to test
+  ■ Used for preliminary research
+
+The Tool: Data Gathering
+  ● Generates, stores, and formats data
+  from selected phone sensors
+    ○ Accelerometer, gyroscope, speed,
+    light, and others
+    ○ Data stored in SQLite database,
+    CSV formatted files
+  ● Allows boolean labeling of data for
+  conditions a user chooses
+
+The Tool: Machine Learning
+  ● Can divide data into
+  training/cross-validation/test sets
+  ● Allows selection of machine
+  learning algorithms on which to
+  train the data
+  ● Measures accuracy of predictions
+  ● Exports results into a report
+    ○ Model parameter values
+    ○ Cost before/after
+    ○ Accuracy, precision/recall
+
+Machine Learning Algorithms
+  ● Supervised learning/Classification
+  ● Developers can code their own machine
+  learning algorithms by implementing an

+  interface (MLAlgorithm)
+  ● A handful of ready-made implementations
+  of MLAlgorithm will be provided
+    ○ SVM, KNN, Random Forest, Naive
+    Bayes, Neural Net?, . . .
+  ■ Weka Machine Learning library
