## Dependencies
- [`tb_db`](https://git.nsrddyn.com/tb_db) — custom CSV query engine / database layer

## Status
Work in progress.
## Output
```bash
[2038] header_index=17, row_index=100, payload=0xfffe9924e087
[2039] header_index=18, row_index=99, payload=0xfffe9924de07
[2040] header_index=19, row_index=98, payload=0xfffe9924db87
[2041] header_index=17, row_index=101, payload=0xfffe9924e327
[2042] header_index=18, row_index=100, payload=0xfffe9924e0a7
[2043] header_index=19, row_index=99, payload=0xfffe9924de27
[2044] header_index=18, row_index=101, payload=0xfffe9924e347
[2045] header_index=19, row_index=100, payload=0xfffe9924e0c7
[2046] header_index=19, row_index=101, payload=0xfffe9924e367
trained value :: 1.062144
Prediction for new house: 2202.942871
```
## Issues
- Children are null.
- Rows are wrong.
- The prediction isn't taking enough parameters.
