<p class="MsoNormal"><span style="mso-fareast-language:EN-US">Dear colleagues,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">Unfortunately, I won’t be able to join you as the time shift is a bit complicated to handle.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">However, there are a couple of things I’d like to share with you.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">First, I had a discussion with the people from CHIME, they are collecting a dataset for the cloud detection algorithm with cloud masks that will be used to test the “multiclass” (only 2 classes for
CHIME) compression. They are willing to share with us the dataset with both the cloud images and the cloud masks once ready.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">Also, in CHIME we have discussed the use of some additional metrics for the compression that could be of interest for the 123B3 green book:<o:p></o:p></span></p>
<ul style="margin-top:0cm" type="disc">
<li class="MsoListParagraph" style="margin-left:0cm;mso-list:l1 level1 lfo2"><span style="mso-fareast-language:EN-US">The covariance between input and ouput<o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0cm;mso-list:l1 level1 lfo2"><span style="mso-fareast-language:EN-US">The crosscorrelation between input and compression error<o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0cm;mso-list:l1 level1 lfo2"><span style="mso-fareast-language:EN-US">The crosscorrelation between output and compression error<o:p></o:p></span></li></ul>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">We had an intern working on compression using the 123B2 with different preprocessing and the Generalised Anscombe Transformation and those metrics were quite insightful, it could be worthed to consider
them.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">I wish you all a good meeting, I’ll try to keep track of the discussions through email.<o:p></o:p></span></p>
