        <description><![CDATA[<h2><strong>An introductory webinar to Upalgo Labeling by Ezako, now available through the Altair Partner Alliance.</strong></h2> <p>Join us for an exciting webinar, where we will explore how&nbsp;<a href="https://altair.com/upalgo-labeling" target="_blank" rel="noopener nofollow">Upalgo Labeling</a>&nbsp;revolutionizes the process of annotating time series and sensor data.<br /><br />In the world of Machine Learning, two prominent techniques emerge: Supervised and Unsupervised learning. While Supervised learning models often achieve higher accuracy, they heavily rely on labeled datasets. On the other hand, Unsupervised learning leverages unlabeled datasets, posing challenges in obtaining accurate labels for training.<br /><br />Enter Upalgo Labeling, the game-changing solution that simplifies and accelerates the annotation of time series and sensor data. Designed with data scientists and data engineers in mind, Upalgo Labeling boasts an efficient user interface and cutting-edge functionalities such as the "candidate generator" and the "label propagator." These powerful features significantly enhance productivity and eliminate the painstaking effort associated with obtaining precise annotations.<br /><br />During this webinar, Ezako Co-Founder &amp; Managing Director Bora Kizil will walk you through the incredible capabilities of Upalgo Labeling. You will learn how this tool streamlines the annotation process, reduces time consumption, and empowers you to unlock the full potential of your time series and sensor data. We will showcase real-world use cases, highlighting how Upalgo Labeling has revolutionized the way data scientists and data engineers approach their projects.<br /><br /></p> <h2><strong>Topics covered include:</strong></h2> <ul> <li> <p>Upalgo Labeling software overview and capabilities</p> </li> <li>Real-world use cases</li> <li> <p>Live Demo</p> </li> <li>Live audience Q&amp;A</li> </ul> <p>&nbsp;</p> <p>Don't miss this opportunity to discover the fastest and easiest way to annotate time series and sensor data.

        <description><![CDATA[<p>Hi All,</p>&#13;
&#13;
<p> </p>&#13;
&#13;
<p>I have spent the past few days learning the basics of&#13;
RapidMiner and looking through the tutorials and existing posts. There are a&#13;
lot of examples on time series prediction comparing existing data against predicted/forecasted&#13;
data and scoring/ranking the two streams against each other.</p>&#13;
&#13;
<p> </p>&#13;
&#13;
<p>I am yet to find any discussion on “predicting into the&#13;
future” where there is no available data. Eg use only the past few years of&#13;
daily data to predict the next 100 days. As always, my question relates to the&#13;
stock price of a single company. </p>&#13;
&#13;
<p> </p>&#13;
&#13;
<p>I have setup my design view to use an ANN as per below. </p>&#13;
&#13;
<p> <img src="https://us.v-cdn.net/6030995/uploads/editor/fj/iwihfyflhwxc.png" alt="" title="Image: https://us.v-cdn.net/6030995/uploads/editor/fj/iwihfyflhwxc.png" srcset="https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=300, width=300/6030995/uploads/editor/fj/iwihfyflhwxc.png 300w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=600, width=600/6030995/uploads/editor/fj/iwihfyflhwxc.png 600w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=800, width=800/6030995/uploads/editor/fj/iwihfyflhwxc.png 800w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=1200, width=1200/6030995/uploads/editor/fj/iwihfyflhwxc.png 1200w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=1600, width=1600/6030995/uploads/editor/fj/iwihfyflhwxc.png 1600w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=2000, width=2000/6030995/uploads/editor/fj/iwihfyflhwxc.png 2000w, https://us.v-cdn.net/6030995/uploads/editor/fj/iwihfyflhwxc.png" sizes="100vw" /></p>&#13;
&#13;
<p>However I would like RapidMiner to predict the next 100 days&#13;
etc into the future where I have no data as shown in the blue drawn line below. Has anyone done this before or would&#13;
know of an example I can examine? </p><p><img src="https://us.v-cdn.net/6030995/uploads/editor/bv/seh7okcv43ei.png" alt="" title="Image: https://us.v-cdn.net/6030995/uploads/editor/bv/seh7okcv43ei.png" srcset="https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=300, width=300/6030995/uploads/editor/bv/seh7okcv43ei.png 300w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=600, width=600/6030995/uploads/editor/bv/seh7okcv43ei.png 600w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=800, width=800/6030995/uploads/editor/bv/seh7okcv43ei.png 800w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=1200, width=1200/6030995/uploads/editor/bv/seh7okcv43ei.png 1200w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=1600, width=1600/6030995/uploads/editor/bv/seh7okcv43ei.png 1600w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=2000, width=2000/6030995/uploads/editor/bv/seh7okcv43ei.png 2000w, https://us.v-cdn.net/6030995/uploads/editor/bv/seh7okcv43ei.png" sizes="100vw" /><br /></p>]]>

        <description><![CDATA[Hi All-<br />[Apologies in advance for any confusing or vague language I may use; I'm not a data scientist, so I don't know the proper terminology.]<br /><br />Say I have a data set of sales volume over time for a retailer that sells screwdrivers. Their product catalog really runs the gamut: flathead, phillips, torx, long, short, every color you can think of, and on and on. If you wanted to forecast demand, you could create a model for one series at a time for each product (e.g. short, yellow, flathead screwdrivers and then medium length, purple, torx drivers with fat handles, etc), or one could aggregate sales for all phillips head screwdrivers or all the different types of screwdrivers in order to collapse them into one series.<br />For some reason, though, let's say you wanted to use all the data from every type of screwdrivers individually to train a model. For each date, you would have data points for every type of screwdriver in inventory. <br /><br />What is the "right way" to represent this in RapidMiner?<br /><br /><a href="https://community.altair.com/profile/sgenzer" rel="nofollow">@sgenzer</a><a href="https://community.altair.com/profile/tftemme" rel="nofollow">@tftemme</a><br />]]>

        <description><![CDATA[Hello Guys<br />I'm working on a final project using rapid miner on COVID-19 data. I did the parameter optimization process. I entered a value for the learning rate in the range of 0.00 - 0.99 with a step count of 10 and for training_cycles in the range 1-200 for a step count of 10. Initially, there was no problem with that value, but when I changed the number of steps in training_cycles to 200, an error appeared like "Cannot reset the network to a smaller learning rate". I want to ask why this happened and how to solve it. If anyone can help out I would really appreciate it.<br /><br />Thank you~]]>

        <description><![CDATA[Hi. I'm new to this but I think I can muddle my way through most of it. The one thing I'm struggling with is that I have a collection of time series examples that I basically want to organise into two groups, True and False, so that I can use the Deep Learning extension on them. What's the best way of applying a label for the DL operator to predict? Is there anyway I can just sort them into two seperate groups? "Tag" the examplesets? Do I just add an extra row at the bottom with True or False in them and get the operator to predict that?<br /><br />Thanks.]]>

        <description><![CDATA[Hi everyone,<br /><br />I just want to do a simple prediction for our company sale numbers. I have data from 2012 to 2020 for one of our product and i just want to predict 2021 year sale number so i can compare it with the real sale numbers.<br /><br />I just do not want to do it with replacing missing numbers with average or other methods. Tried to do it with "replacing missing numbers (time series)" operator with linear interpolation but it seems it can not replace the last line of missing value. How can i solve this or should i use knn, decision tree or neural network to predict it?<br /><br /><div>If we manage to predict number i also want to compare the methods' prediction values. i would appreciate if it is a simple solution like (hard to understand and explain root mean squared error to boss for example) comparing the prediction values how close to real numbers. <br /><br />Maybe i did all the process wrong but ty for your answers i am still trying to learn.<br /><br /></div><div><img src="https://us.v-cdn.net/6030995/uploads/editor/i2/kzopxqrqekfk.jpg" alt="" title="Image: https://us.v-cdn.net/6030995/uploads/editor/i2/kzopxqrqekfk.jpg" srcset="https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=300, width=300/6030995/uploads/editor/i2/kzopxqrqekfk.jpg 300w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=600, width=600/6030995/uploads/editor/i2/kzopxqrqekfk.jpg 600w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=800, width=800/6030995/uploads/editor/i2/kzopxqrqekfk.jpg 800w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=1200, width=1200/6030995/uploads/editor/i2/kzopxqrqekfk.jpg 1200w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=1600, width=1600/6030995/uploads/editor/i2/kzopxqrqekfk.jpg 1600w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=2000, width=2000/6030995/uploads/editor/i2/kzopxqrqekfk.jpg 2000w, https://us.v-cdn.net/6030995/uploads/editor/i2/kzopxqrqekfk.jpg" sizes="100vw" /></div><br /><br /><br />]]>

        <description><![CDATA[<div>Hello,</div><div>Does RapidMiner have any operator that can determine the seasonality of a time series? My idea is that the input is a dataset with an attribute specified as the target, and the output (perhaps among other things) figures out the seasonality pattern (e.g. 12 for annual seasonality on monthly data, 7 for weekly seasonality on daily data, 168 for weekly seasonality on hourly data, etc.). <br /></div><div>I know that R can do this with auto.arima, but does RapidMiner have such a feature built in? (If not, I know that I could use the R Scripting extension to run the R function.)</div><div>Regards,</div><div>Chitu<br /></div>]]>

        <description><![CDATA[Dear All,<br /><br />I am a terrific newbie on rapidminer. I need to extract dominant cycles (peaks of frequencies) on a time series of the financial tools, in the example of S&amp;P future, candlesticks on 1-minute timeframe. I have previously calculated per minute the average price value (high+low)/2 and then the moving average on 10 periods (minutes) to smooth a bit of noise. Then I have calculated the FFT. The calculation is made generating frequency but not considering the timestamp column since there are ranges of time during which there are no exchanges (Saturday, Monday, night...) and they have not to count az missing or zero values. Said this, I have at this point several questions. The generated FFT is as in the following screenshot table, on the FFT amplitudes it has been applied a log since some components have too high magnitude than others<br /><br /><img alt="" src="https://us.v-cdn.net/6030995/uploads/editor/w8/u8kvyjbkoq19.gif" title="Image: https://us.v-cdn.net/6030995/uploads/editor/w8/u8kvyjbkoq19.gif" srcset="https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=300, width=300/6030995/uploads/editor/w8/u8kvyjbkoq19.gif 300w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=600, width=600/6030995/uploads/editor/w8/u8kvyjbkoq19.gif 600w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=800, width=800/6030995/uploads/editor/w8/u8kvyjbkoq19.gif 800w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=1200, width=1200/6030995/uploads/editor/w8/u8kvyjbkoq19.gif 1200w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=1600, width=1600/6030995/uploads/editor/w8/u8kvyjbkoq19.gif 1600w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=2000, width=2000/6030995/uploads/editor/w8/u8kvyjbkoq19.gif 2000w, https://us.v-cdn.net/6030995/uploads/editor/w8/u8kvyjbkoq19.gif" sizes="100vw" /><br /><br />if I display the FFT spectrum as a Histogram I obtain the following result:<br /><br /><img alt="" src="https://us.v-cdn.net/6030995/uploads/editor/cl/1neex4t59ela.gif" title="Image: https://us.v-cdn.net/6030995/uploads/editor/cl/1neex4t59ela.gif" srcset="https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=300, width=300/6030995/uploads/editor/cl/1neex4t59ela.gif 300w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=600, width=600/6030995/uploads/editor/cl/1neex4t59ela.gif 600w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=800, width=800/6030995/uploads/editor/cl/1neex4t59ela.gif 800w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=1200, width=1200/6030995/uploads/editor/cl/1neex4t59ela.gif 1200w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=1600, width=1600/6030995/uploads/editor/cl/1neex4t59ela.gif 1600w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=2000, width=2000/6030995/uploads/editor/cl/1neex4t59ela.gif 2000w, https://us.v-cdn.net/6030995/uploads/editor/cl/1neex4t59ela.gif" sizes="100vw" /><br /><br />The shape could be coherent, but not the labels on the X and Y axes that appear inverted. I have selected as values columns "HL/2_filtered_amplitude" and what I expect is that this field is the Y axe. So the first question is<br /><br />Q1: why axes are inverted?<br /><br />and<br /><br />Q2: despite the labels, is the histogram really showing on the Y the amplitude of the frequency spectrum and on X the frequency?<br /><br />Note that if I change the values columns field and select the "frequency" column I get a flat histogram.<br /><br /><img alt="" src="https://src" srcset="https://community.altair.comsrc/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=300, width=300 300w, https://community.altair.comsrc/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=600, width=600 600w, https://community.altair.comsrc/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=800, width=800 800w, https://community.altair.comsrc/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=1200, width=1200 1200w, https://community.altair.comsrc/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=1600, width=1600 1600w, https://community.altair.comsrc/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=2000, width=2000 2000w, src" sizes="100vw" /><img src="https://us.v-cdn.net/6030995/uploads/editor/gu/yygoomioglwz.gif" alt="" title="Image: https://us.v-cdn.net/6030995/uploads/editor/gu/yygoomioglwz.gif" srcset="https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=300, width=300/6030995/uploads/editor/gu/yygoomioglwz.gif 300w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=600, width=600/6030995/uploads/editor/gu/yygoomioglwz.gif 600w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=800, width=800/6030995/uploads/editor/gu/yygoomioglwz.gif 800w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=1200, width=1200/6030995/uploads/editor/gu/yygoomioglwz.gif 1200w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=1600, width=1600/6030995/uploads/editor/gu/yygoomioglwz.gif 1600w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=2000, width=2000/6030995/uploads/editor/gu/yygoomioglwz.gif 2000w, https://us.v-cdn.net/6030995/uploads/editor/gu/yygoomioglwz.gif" sizes="100vw" /><br /><br />Q3: how can I pot correctly the FFT amplitude with an histogram chart?<br /><br />If I change the type of chart for instance lines and set on Y and X the proper columns I get something very different and with an unexpected shape<br /><br /><img alt="" src="https://us.v-cdn.net/6030995/uploads/editor/u4/hs86vsypoys4.gif" title="Image: https://us.v-cdn.net/6030995/uploads/editor/u4/hs86vsypoys4.gif" srcset="https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=300, width=300/6030995/uploads/editor/u4/hs86vsypoys4.gif 300w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=600, width=600/6030995/uploads/editor/u4/hs86vsypoys4.gif 600w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=800, width=800/6030995/uploads/editor/u4/hs86vsypoys4.gif 800w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=1200, width=1200/6030995/uploads/editor/u4/hs86vsypoys4.gif 1200w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=1600, width=1600/6030995/uploads/editor/u4/hs86vsypoys4.gif 1600w, https://us.v-cdn.net/cdn-cgi/image/quality=80, format=auto, fit=scale-down, height=2000, width=2000/6030995/uploads/editor/u4/hs86vsypoys4.gif 2000w, https://us.v-cdn.net/6030995/uploads/editor/u4/hs86vsypoys4.gif" sizes="100vw" /><br /><br /><br />Q4: is this chart showing correctly the X and Y axes?<br /><br />The other big question is on frequency interpretation: provided that<br /><br />1. i do not declare the timestamp column<br />2. the values are given with a time interval of 1 minute<br />3. i do not know the number of samples considered<br />4. I checked the "calculate frequency" option<br /><br />Q5: What does the number on the frequency axe represent? is it correct to interpret the N value as a period 1/N minutes?<br /><br />Thank you a lot, in case I can provide a link to download the project.]]>

I have a few thousand examples I want to use to be able to predict whether or not an event is going to occur. I've been tidying the data up in Python so far but I want to move to RapidMiner.<br /><br />My examples contian multiple attributes. Everything I read about Time Series talks about using just one attribute and pivoting the data so one example is on a single row. this obviously doesn't work when there's multiple attributes.

        <title>Time Series using Windowing operator in RapidMiner</title>

        <description><![CDATA[<p>I'm trying to use a time series model in RapidMiner to forecast premium paid to an insurance company. Specifically, I have an entry for each month from January 2009 - December 2015, I want to be able to forecast the data for the next 12 months (January 2016-December 2016).</p>
<p>I'm having trouble understanding how the Windowing operator works, I have a few questions:</p>
<p>1) What goes into selecting a window size? If I want to forecast Premium over the next 12 months, is my window size 12? And if so, why do I get 12 attributes for each original attribute in my data set (the original Premium amount in one of these 12)? I get that this is supposed to explain the corresponding label value (which is just the next row's original Premium, not sure why this is happening either), but where are these numbers coming from and why does RapidMiner generate these?</p>
<p>2) What does the option "create single attributes" do?</p>
<p>3) The horizon field: If this is the distance between the last window value and the value to predict, does this mean I can't at once predict the next 12 months of data? Even if I enter the horizon as 1 (which I take to mean, give me the prediction for January 2016 since the last data point is for December 2015), then why is there no label value for December 2015 or January 2016 in the output when I run the process?</p>
<p>I'm a beginner, and I would really appreciate any help!</p>]]>

        <description><![CDATA[Hi guys, I am a newbie in RapidMiner and am trying to do Time Series Analysis combined with sensex. I have forecasted values with Arima model and I would like to compare forecasted value in row x with real value in row x-1. I tried using Generate attributes operator but I am unsure on how to reffer to different attributes and rows. Does anyone have a suggestion on how to solve this?<br /><br />Thanks<br />]]>
