no member named w in the linear_regression structure

[wyoung1]

Dear İbrahim Ümit Akgün,

I'm sorry to bother you. I am writing to bring to your attention a bug that I encountered while reviewing the code in mq-adios.c in the kernel-ml-linux repository.

Upon inspecting the code at line 495 of mq-adios.c, I noticed the following snippet:

io_sched_linear = build_linear_regression(0.03, 10, 0.99, 2);
io_sched_linear->check_correctness = io_scheduler_linear_check_correction;
set_random_matrix(io_sched_linear->w, modula);
The variable io_sched_linear is of type struct linear_regression, as defined in linear_regression.h. However, it appears that there is no member named w in the linear_regression structure. This inconsistency has resulted in compilation errors.

Here is the relevant definition of the linear_regression structure:

typedef struct linear_regression {
int batch_size;
sgd_optimizer *sgd;
loss *loss;
layers *layer_list;
bool (*check_correctness)(val result, val prediction);

model_data data;
model_multithreading multithreading;
model_state state;
} linear_regression;
Could you please look into this issue and provide a fix? It seems that there may be a discrepancy between the code in mq-adios.c and the definition of the linear_regression structure.

Thank you for your attention. I appreciate your efforts in maintaining the kernel-ml-linux repository.

Best regards,
