machine learning for java

Detect all inverse parabolas in a graph, and give their coeficients in an array using java. The java function must return an array of all the inverse parabolas equation coeficients (a,b,c in ax2+bx+c=0 ) of any xy data source provided with polinomial regresion grade 2 (cuadratic equation). To test it, find all the inverse parabola equations of the (x,y) data provided. See the sample image. Configurable sensitiveness .
