What is the criteria for a ML paper to be published?[D]

I'm going to attend a conference soon with my academic supervisor. I want to know what I should be expecting as I'm new to this field. To be specific, I'm forecasting a stock index using macroeconomic variables, where the results are robust (addressed non-stationarity and such), but have small predictive power. I've applied SHAP to a random forest model where I noticed that it struggles with regime shifts (like oil becoming a liability instead of an asset depending the period) which is explainable because it didn't learn the inverted relationship.
