kandi X-RAY | MKR Summary
This repository is the implementation of MKR (arXiv):. Multi-Task Feature Learning for Knowledge Graph Enhanced Recommendation Hongwei Wang, Fuzheng Zhang, Miao Zhao, Wenjie Li, Xing Xie, and Minyi Guo. In Proceedings of The 2019 Web Conference (WWW 2019). MKR is a Multi-task learning approach for Knowledge graph enhanced Recommendation. MKR consists of two parts: the recommender system (RS) module and the knowledge graph embedding (KGE) module. The two modules are bridged by cross&compress units, which can automatically learn high-order interactions of item and entity features and transfer knowledge between the two tasks.

QUESTION
I've trying to work out why someone would write the following section of code in a Arduino loop. To me, it doesnt make sense, why have a return in a if statement? Does it just return to the start of the loop and not carry on with the rest of the loop. Here's the snippet of interest:
...ANSWER
Answered 2021-Jun-08 at 19:34After return ; or just return; (for void functions) the program exits from the loop and also from function. The function returns (for non-void functions). This statement applies when executing function already is not requeris.
QUESTION
I'm running an algorithm to predict prices and enter trades for me using the ccxt API in python. I wish to execute a trailing stop loss order and I enter such a long position like this:
...ANSWER
Answered 2021-Apr-24 at 12:29Binance REST API doesn't support TRAILING_STOP_MARKET, see "Order types" in the Enum definitions.
If you want to simulate a trailing stop order, you'll need to subscribe to the trade stream and keep recalculating your stop price. When the current market price reaches the stop price, submit a new order.

I have a component that displays a grid of elements. These elements are all composed by the same thing except that each element has a different city and price.
This city and price I am grabbing from a data.js file I got.
At the moment this is my code:
...ANSWER
Answered 2021-Jan-24 at 17:16A better approach would be to create a seperate component for displaying a single city information and then use that component for displaying each city.

QUESTION
I have a problem with my new project. The goal is to control my piezo motor with an Arduino MKR Wifi 1010 via RS485. For that reason I have these components:
Arduino MKR Wifi 1010 Arduino MKR 485 Shield Piezo Motordriver PM401 (Manual: https://piezomotor.com/wp-content/uploads/2019/03/150025_PMD401_Technical_Manual.pdf) Piezo LEGS motor
I tested the RS485 by using a USB adapter and the piezomotor software. That worked. But if it comes to code, I don't get any further.
The commands I want to send the piezodriver in ASCII Code is:
X127M2;
X127J200,0,100;
(They worked in the PiezoMotor DriveLab Software)
And I try to do it with this code:
...ANSWER
Answered 2021-Jan-14 at 11:06Do I need a adress? And if, how do I get it.
This is explained in the manual... Read it!
Also is the Piezodriver Half or Full duplex?
The manual only lists one pair of data pins. So it must be half-duplex.
but the example code said it have to be Full Duplex.
The MKR 485 shield supports both half- and full duplex. Read the manual.
The commands I want to send the piezodriver in ASCII Code is:
X1M2;
X1J200,0,100;
According to the manual commands are terminated with carriage-return. Why do you put a semikolon at the end of the commands?
RS485.write(X1J200,0,100;); and RS485.write('X1M2;'); will not even compile.
Replace you need to use double quotes. Using none or single quotes won't work.
Your commands should looke something like RS485.write("X1M2\r");
QUESTION
I have recently been playing with the Arduino MKR Vidor 4000, and I have run into a small problem. I want to be able to reuse code (like with a function in C++) and have the defined variables local to the piece of code, so they don't interact. I have come across Tasks in Verilog, and these seem to be the correct way of doing this.
The problem is, I can't get Quartus to compile it. It just reports an error:
Error (12006): Node instance "comb_6" instantiates undefined entity "test". Ensure that required library paths are specified correctly, define the specified entity, or change the instantiation. If this entity represents Intel FPGA or third-party IP, generate the synthesis files for the IP.
Here is my code:

Answered 2020-Oct-17 at 15:31I have put the code I wanted to be able to reuse in a module, and it works okay now! I am not sure if this is what I should be doing, so if anyone has a better way to do it, then I'm all ears!
I have, effectively, done this:
QUESTION
I am writing a serial communication program between a mkr wifi 1010 and a mega in which the mkr sends either a H or L char to the mega, and the mega responds by reading the char and setting it's onboard LED to either high or low depending on the char. When I use delay(#) on the mkr the code works just fine and the mega's LED blinks on and off.
However when I create delay-less code the mega's led will not blink. It either stays low or stays high, most of the time stays low. I have checked the mkr code by reading the serial port and it indeed sends 72(H) and 76(L) alternately at the correct interval in both versions of the code.

QUESTION
I'm using the cryptocompare API and trying to pull the historical data for a bunch of different tickers.
Tickers are read from an excel spreadsheet and then loaded through the API to get the historical prices for each ticker.
This is the dataframe that I am currently receiving: https://docs.google.com/spreadsheets/d/1jQ7F0H2D-voTBxjHI3QVPTRNyR4m4qKob8NE04JWVY0/edit?usp=sharing
I am wondering a few things:
- How do I get the index to be the date and
- How would I access just the 'close' data point?
This is currently my code:
...ANSWER
Answered 2020-Sep-22 at 19:39- The file is columns of
dicts, asstrings, for each ticker symbol. - Load your file with
pandas.read_excel. - Convert the
strtypes todicttypes, usingast.literal_eval. - Convert each column of
dictsto a dataframe withpandas.json_normalize.- Each dataframe will be added to a
dict,df_dict, where the keys will be the tickers.
- Each dataframe will be added to a
- Add the ticker as a column to each dataframe
- Combine all of the dataframes into a single dataframe, with
pandas.concat. - Convert the
'time'column to a datetime format withpandas.to_datetime, and set as the index. - Access the
'close'column withdf.closeordf['close']. - Use
pandas.DataFrame.pivotto get'close'as values, with the tickers as headers and'time'as the index.

Install MKR
You can use MKR like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
