Time-Series Forecasting for Virtual Item Prices

This repository contains trained machine learning and deep learning models for forecasting the price direction of virtual assets based on time-series data.

Best Model

The best performance was achieved by the LSTM neural network on the Kneedle (MAE <= 0.416) data pool, yielding a metric of ROC-AUC = 0.6567.

Final model architecture:

LSTM(128) – recurrent layer, tanh activation
Dropout(0.3)
Dense(64, ReLU)
Dense(1, sigmoid) – probability of price increase

Repository Structure

lstm_final_kneedle.keras — the main optimized model.
lstm_final_kneedle_cosmetics.keras — model for the alternative dataset (appendix).
best_experiments/ — the best models across 14 different algorithms (CatBoost, XGBoost, TabNet, etc.) after pool optimization.
