huevosabio / cs341 Goto Github PK

Dear authors,

I found some files still can not be derived from the code base.

For example, LSTMPrediction.ipynb needs to load some files (e.g., 'ignored_assets/to_lstm_3b_3f.csv', 'ignored_assets/new_lstm_to_pred.csv') to generate different predictor for Matlab simulation part, I searched the whole cs341 code base but found nowhere to generate those files.

Now I can only use LSTMPrediction.ipynb to generate empty predictor, and simulate no prediction scenario.

I want to simulate with prediction part, could you please give me some advice?

Dear authors,

Thanks for your last reply, I can study the prediction module.

Here, I have questions about Line 552, 556 in Road_network_sim.m.
Line 552: Passengers.FlowsIn(1:predleftin,:) = Passengers.FlowsIn(1:predleftin,:); + double(FlowsIn{currentTime}(1:predleftin,:));
Line 556: Passengers.FlowsOut(1:predleftout,:) = Passengers.FlowsOut(1:predleftout,:) + double(FlowsOut{currentTime}(1:predleftout,:));

The number of rows in Passengers.FlowsIn and Passengers.FlowsOut is both horizon, i.e., 50 (For convenience, I only use FlowsIn to illustrate), which means 50 timesteps in 5 min.

Passengers.FlowsIn with shape (50*66) means how many cars will arrive at each station in the future 5min.

The number of rows in FlowsIn{currentTime} is the number of car arriving time buckets, where these cars start in the future 2h (25 timesteps, 2h/5min) form currentTime.

FlowsIn is loaded from GoodPrediction.ipynb. FlowsIn{currentTime} with shape (#time_bucket_arrival * 66) means from now (currentTime), in the future some time buckets, how many cars will arrive at 66 stations.

So the meaning of row in Passengers.FlowsIn and FlowsIn{currentTime} is different. Why the two variables can be directly added in Line 552?

Thank you.

Dear authors, the original data (orders.csv) from DiDi is excluded from the code base. DiDi's GAIA website has been unavailable for a period, so I am still unable to find the data. Dr. Qingwen has not replied to me. 😱 Do you have any backups for that data?
