Batch Processing
Training
For a description of the input and output, refer to Recommendation Systems Usage Model.
At the training stage, the implicit ALS recommender has the following parameters:
Parameter |
Default Value |
Description |
---|---|---|
algorithmFPType |
float |
The floating-point type that the algorithm uses for intermediate computations. Can be float or double. |
method |
defaultDense |
Available computation methods:
|
nFactors |
10 |
The total number of factors. |
maxIterations |
5 |
The number of iterations. |
alpha |
40 |
The rate of confidence. |
lambda |
0.01 |
The parameter of the regularization. |
preferenceThreshold |
0 |
Threshold used to define preference values. 0 is the only threshold supported so far. |
