Traning neural networks with extension R in NetLogo -


i creating supply chain simulation netlogo. putting list of lists netlogo r, represented distributor id (agents who) , sales history (sales of previous ticks). in r train neural network , make predictions. when put answer in same format list of lists. need specify result goes agent. however, not know how in netlogo. assume there should function that, understand functions programmed java , need assign values inside raw code , not in netlogo environment. moreover, think training , predictions occurs multiple times (for each agent) , not once.

variable example: [ [0] [ 100 200 300 100 200] ] [ [1] [ 200 300 100 100 200] ]

where first index agents index , second agent's sales history.

maybe explain how netlogo , r can combined computational purpose , not statistical analysis , plotting? assume netlogo similar parallel programming, while style of r programming more linear.

the last part of question beyond me (and may broad typical stack overflow questions- i'm not sure you'll useful answer here). however, maybe example in right direction you're trying do.

i assume you're using [r] extension in previous question, using setup: 

extensions [r]  turtles-own [ rand-num ]  setup   ca   crt 10 [     set rand-num random 5   ]   reset-ticks end

in example, turtles have rand-num instead of sales history, concept same. first, build list of lists first index turtle [who] , second [rand-num], output r (note sort list, clarity , not needed):

to go    let l_list map [ ->     list [rand-num] of turtle   ] ( sort [ ] of turtles )    r:put "list1" l_list    show r:get "list1"

next, use r:eval whatever need values in r- in example i'm using lapply square rand-num value (x[[2]])- make sure return x:

let modified_list ( r:get "lapply(list1, function(x) { x[[2]] <- x[[2]]^2; return(x)})" )

now, assign turtles modified values, use netlogo's foreach iterate on modified list , ask turtle of index 0 (turtle item 0 x) set rand-num index 1 (set rand-num item 1 x):

  foreach modified_list [ x ->     ask turtle item 0 x [       set rand-num item 1 x     ]   ]  end

if check sort [rand-num] of turtles before , after running go, should see rand-num of each turtle squared after go called.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
