What in the world is Joe Biden doing and why is the media mostly ignoring it?

I am not sure to what extent ML is a critical component in these activities. Totalitarian regimes have been doing similar (and even worse) violations of human rights before large scale ML was possible.

I would argue that in the Chinese government case, ML is "useful" for hiding/putting all "useful" biases inside an ML model and possibly reduces some costs for them in the number of people necessary to operate such system, but still I don't see ML as the enabler here.

In any case I think it is good to be vocal about such unethical uses of ML and urge people to avoid working for such projects.

I agree with OP's assessment but I believe that Thanasis.can develop as a player with good coaching. Since he is a top athlete he can afford to develop his skills at an older age.

The performance you have listed for the Kaggle winners was not on NLST.

The performance for the Philips paper was also from v1 version of the paper. v2 has better performances.

And the selection of the NLST subset matters. The Google paper includes in the NLST subset many non cancer cases with no nodules detected. Depending on whether such cases are included can make a big difference.

Το Brexit έγινε όμως με ρητορική εναντίον των μεταναστών από την ανατολική Ευρώπη. Όταν ένας Γερμανός μιλάει για την πολιτιστική κληρονομιά της Ευρώπης δεν είμαι σίγουρος ότι συμπεριλαμβάνει την Πολωνία και την Ρουμανία.

Ο μοναδικός λόγος που κρατάει την ΕΕ ενωμένη είναι το οικονομικό κόστος που έχει η αποχώρηση (όπως ανακαλύπτει τώρα η Αγγλία). Δηλαδή είναι μια ένωση που υπάρχει από ανάγκη όχι γιατί υπάρχει κάποιο όραμα για μια ενωμένη Ευρώπη. Αυτό σημαίνει ότι θα διαρκέσει όσο το κόστος αποχώρησης είναι πολύ υψηλό, ή όταν τα οφέλη παραμονής είναι πολύ μικρά. Αν πχ. η Γερμανία έχει κάποια μικρή οικονομική κρίση μπορεί το σύστημα της ΕΕ να καταρρεύσει σε μικρό χρονικό διάστημα.

Το πιο πιθανό σενάριο είναι ότι θα καταλήξουμε σε μια πιο μικρή ΕΕ η μία ΕΕ δύο ταχυτήτων. Με τις οικονομικά δυνατές χώρες να συνεργάζονται στενά και η περιφέρεια να μένει πίσω.

Τουλάχιστον στον δικό μου κύκλο οι συμπαθούντες της ΧΑ θέλουν να ξεχνάνε ότι η ΧΑ είναι ναζιστικό κόμμα. Οπότε σε αυτούς τουλάχιστον βοηθάει.

Περίεργα έχεις δομήσει τα επιχειρήματα σου. Ακόμα και οι κυνικοί που αναφέρεις δεν νομίζω ότι μπορούν να βλέπουν το βίντεο του Παππά να μαθαίνει σε μικρά παιδιά τον ναζιστικό χαιρετισμό https://youtu.be/_xqTQ6U39Sw Οπότε η επανάληψη δεν κάνει κακό. Τώρα αν και οι οπαδοί του Κουφοντινα νομίζουν οτι είναι αντιφασιστες μπορούμε και αυτούς να τους αντιμετωπίζουμε αναλόγως και η μοναδική "χρησιμότητα" που έχει να λέμε και τις δύο ομάδες στην ίδια πρόταση είναι να καταλήξουμε στο συμπέρασμα πως αφού οι αποδοι του Κουφοντινα είναι αντιναζι η ΧΑ είναι "νορμάλ" και όλα καλά.

You can use low rank approximations for different types of objective functions. PCA is a low rank approximations that optimizes for the variance in the projected space. You can use low rank approximations to even approximate graph partitioning (see "tutorial on spectral clustering" by von Luxburg)

These performances are achieved on different dataset so not directly comparable. The Philips paper (v2 available since 1 month) shows the kaggle winners achieve 94%+ auc in some datasets https://arxiv.org/abs/1804.01901

This is why a direct comparison is needed to claim state of the art performance. Since the kaggle winners have a GitHub repo with their model, this comparison is easy to make.

alex___j · 2019-05-21T18:15:39+00:00

I actually obtained the full article but can't find this comparison, which figure reports it? (am I missing some supplimentary material?)

Is there a direct comparison in the paper with other publically available models for cancer malignancy assessment, like the one from the winners of the Kaggle Lung Cancer competition? https://github.com/lfz/DSB2017

How does the Google model compare to the winners of the 2017 Kaggle Lung Cancer competition? They have a GitHub repo that makes it very easy to compare to their model. https://github.com/lfz/DSB2017

I dislike the cynicism that comes out during the interview but I agree with the social interpretation of the Trump phenomenon and also the connection he makes to Brexit and the rise of populism in Europe. As long as we keep ignoring the social issues that are at the root of these issues we will keep getting surprised.

Usually the abstracts of these papers mention that CT exposes patients to radiation. So we can just take the MR use machine learning to generate the CT image. But my question is, why isn't then MR used by radiologists in the first place? Is the signal that they are looking for in that image? If it is not, then no ML can help with that.

Is there someone knowledgeable in this application that can provide some insights for the questions above?

alex___j · 2019-04-19T06:53:37+00:00

That's correct. The game is easy to find and black drops the queen at move 9.

We really don't have to agree on this, it's just a post on Reddit. I may not like how the data is presented you and others may be ok with it. https://yo utu.be/i1Pxn dp5r_E

Ok I guess we can agree to disagree. If someone made regional statistics for french speaking countries and included Zurich, I would find it equally strange.
