## FEAST main function (fast version)

### Description

FEAST main function (fast version)

### Usage

    FEAST_fast(
      Y,
      k = 2,
      num_pcs = 10,
      split = FALSE,
      batch_size = 1000,
      BPPARAM = bpparam()
    )

### Arguments

`Y` | A expression matrix. Raw count matrix or normalized matrix.
`k` | The number of input clusters (best guess).
`num_pcs` | The number of top pcs that will be investigated through the consensus clustering.
`split` | boolean. If T, using subsampling to calculate the gene-level significance.
`batch_size` | when split is true, need to claim the batch size for spliting the cells.
`BPPARAM` | parameters for BiocParallel. e.g. bpparam() and SnowParam.

### Value

the rankings of the gene-significance.

### Examples

    data(Yan)
    k = length(unique(trueclass))
    res = FEAST_fast(Y, k=k)
