In my CSV I have inconsistent data so I have to log the error while iterating record and want to create a list of POJO of valid CSV records. I am using OpenCsv to process the CSV file. I have added try-catch block to log the error if there is any but at while(iterator.hasNext()) there is the exception/error as next record has some incorrect formatted data.

So how to log the error and continue to process the next record?

I have a question about gsub of part string if condition match....

I am using CesiumJs. I would like to create point D at distance C from point A using the direction B

I'm using a function based on argparse to use it with different options and calculations on this options.

This works perfectly:

I'm new on python and I was wondering how to call a function based on argparse on a selective structure

I tried this function

I am trying to calculate the Kullback-Leibler divergence from Gaussian#1 to Gaussian#2 I have the mean and the standard deviation for both Gaussians I tried this code from http://www.cs.cmu.edu/~chanwook/MySoftware/rm1_Spk-by-Spk_MLLR/rm1_PNCC_MLLR_1/rm1/python/sphinx/divergence.py

The following is self-contained, and when you run it it will:

1. print the loss to verify it's decreasing (learning a sin wave),

2. Check the numeric gradients against my hand-derived gradient function.

The two gradients tend to match within 1e-1 to 1e-2 (which is still bad, but shows it's trying) and there are occasional extreme outliers.

I have spent all saturday backing out to a normal FFNN, getting that to work (yay, gradients match!), and now sunday on this LSTM, and well, I can't find the bug in my logic. Oh, and it's heavily depends on my random seed, sometimes it's great, sometimes awful.

I've hand checked my implementation against hand derived derivatives for the LSTM equations (i did the calculus), and against the implementations in these 3 blogs/gist:

• http://blog.varunajayasiri.com/numpy_lstm.html

• https://gist.github.com/karpathy/d4dee566867f8291f086

• http://colah.github.io/posts/2015-08-Understanding-LSTMs/

And tried the (amazing) debugging methods suggested here: https://blog.slavv.com/37-reasons-why-your-neural-network-is-not-working-4020854bd607

Can you help see where I have implemented something wrong?

I have written a js code for removing 31st date column.

So, I'm having trouble with the legend of a multiple line/point/bar plot. Just the lines appears and I couldn't change its names neither add the bar element to it, here's the code I´m running:
