QUESTION
I try to find the optimal number of topics in the LDA algorithm for my database. For this purpose I try to use the package "ldatuning". After the implementation of the LDA algorithm with the "gibbs" method I try to use the function:
Griffiths2004(models, control) The arguments should be: models An object of class "LDA control A named list of the control parameters for estimation or an object of class "LDAcontrol".
I used it like that:
...ANSWER
Answered 2021-Jun-15 at 11:13The problem probably lies in how you pass the control parameter list to the Griffiths2004 function.
In the Griffiths2004 function, the parameters are addressed as in a list using control$param
. However, lda_5@control
returns an S4 object where the parameters should be addressed with control@param
. (An S4 object is an advanced class in R, but the only important difference for this application is, that we address objects in these lists with @ instead of $)
You can see that lda@control
is an S4 object when calling it:

) followed by either one or more space, comma ([, ]+

and digits (\\d+
) and other characters (.*
) or (|

QUESTION
I am new to MIPS assembly. I am trying to convert a java code to MIPS code but I can't figure it out that how can I load and store double values in MIPS. I get this error "address not aligned on doubleword boundary 0x10010001". Here is the java code:
...ANSWER
Answered 2021-Jun-14 at 17:49Use syscall function code 3 to print doubles (not function code 2 — that's for single float).
Use mov.d
to copy one register to another, e.g. into $f12
for sycalls (then no need to load 0.0 into $f0
).
(Also, use l.d
instead of ldc1
.)
The loop:
loop isn't a loop (there is no backward branch for it).
As @Peter says, your scaling/offsets are not properly accounting for the size of double, which is 8. Scaling needs to multiply by 8 (shift by 3, not 2), and offsets need to be multiples of 8.
Your first loop, when its done, should not EXIT the program but rather continue with the next statement (i.e. the printing loop).
For this statement numbers[i+2] = numbers[i+1] + numbers[i];
there are two loads and one store as array references, whereas the assembly code is doing 3 loads and no store.
You use $s5
, but never put anything in it.
The comparison of numbers[i+1] < 150
has to be done in (double) floating point, whereas the assembly code is attempting this in integer registers.
Floating point comparison is done using c.eq.d
, c.lt.d
, or c.le.d
. Like with integer compares, constants need to be in registers before the compare instruction. 150.0 would best come directly from memory (as a double constant) before the loop and remain there for the loop duration (or you can move integer 150 into a floating point register and convert that to double (cvt.w.d
)).
Conditional branches on floating point compare conditions use either bc1t
or bc1f
(depending on the sense you want).
The C-like pseudo code probably doesn't run properly. The exit condition for the first loop is suspect — it will probably run off the end of the array (depending on its initial data values).
Translating non-working C code into assembly is a recipe for frustration. Suggest getting it working in C first; run it to make sure it works.

I have a small follow-up question to a previous one answered here. With a dummy dataset as included below, I would like to filter off rows in which one or more of the samples (denoted S1, S2, S3, S4 in the dataset) has only "1" and "0", as well as all rows where the samples have only 1", "0" and "."

E 13 0 0 0 0 F 14 1 1 1 1 G 10 1 0 0 0In other words, I want to keep only those rows that either has "1" in all the samples, or "0" in all samples, or "1" and "." in all samples, or lastly those with "0" and "." such that at the end, I have the final dataset looking as below
ID Pos S1 S2 S3 S4 C 50 0 . . . D 11 . 1 . . E 13 0 0 0 0 F 14 1 1 1 1I am trying to do this in R and I request any suggestions from you.
