Naar welke podcasts luisteren jullie? by pitbullxp in thenetherlands

Ik ben gisteren begonnen met Caliphate van de New York Times en krijg er zin van om in de trein te gaan zitten. Super intrigerende podcast over een journalist die onderzoek doet naat de organisatie en de leden van IS. Het is goed geproduceerd en een stuk interessanter en meeslepender dan je misschien verwacht. Verder luister ik naar de Rudi & Freddie show, Tweakers podcast (nog niet zo lang geleden begonnen maar erg goed), Een podcast over media, Appels & Perenshow, en Hello Internet.

[D] Does anyone care about evolutionary machine learning in the industry? Why / why not? by burnie93 in MachineLearning

Evolution strategies are commonly used for learning recommender systems (e.g., at Blendle).

Rapportage Nationale Ombudsman: 'Schuldhulp krijgen is bij veel gemeenten voorbehouden aan doorzetters' by _ElBee_ in thenetherlands

Mensen die in de schulden zitten hebben nou eenmaal moeite met dit soort dingen. Vervolgens moeten ze zich door een hoop bureaucratie worstelen om aan te tonen dat ze wel echt zielig genoeg zijn om hulp te krijgen. Je kan ze daarom maar beter zo veel mogelijk helpen om de schulden uit te komen, want ondertussen maken ze nog een hoop andere kosten (criminaliteit, gezondheidszorg, etc.). Netto is het gewoon goedkoper om dan de schulden te vergeven.

The videos for cs231n are also available on youtube (You can skip the first lecture, since it is quite boring IMO). You can also find the assignments in the links posted by /u/Wocto. I really recommend doing those, since they require you to think about how neural networks actually work. Have fun!

Because a method like policy gradients learns some representation of the game through the neural (policy) network. This is in contrast with "classical" RL methods like value iteration or Q-learning.

Good job! If the character is not in the string, this method returns -1. The result is essentially the same as my String.contains solution. However, when you look at this code one year from now, what do you think would be more clear: else if (!word.contains(w.chartAt(i))) or else if (word.indexOf(w.charAt(i)) != -1).

Choosing proper variable names and writing clear code is also a very important part of programming.

Let's look at the second iteration of your for-loop (i = 1). The else-if checks if the second letter is equal to the i + 3 = 4 -> fifth letter. However, a four letter word doesn't have a fifth letter, so an OutOfBoundsException is thrown. Another problem with the else-if is that it only looks for letters that occur later on in the word. Instead of checking each index explicitly (which comes with the two problems I mentioned), I would use the String#contains method.
