arunreddy / pad_packed_demo.py
Created September 27, 2022 13:44 — forked from HarshTrivedi/pad_packed_demo.py
Minimal tutorial on packing (pack_padded_sequence) and unpacking (pad_packed_sequence) sequences in pytorch.
import torch
from torch import LongTensor
from torch.nn import Embedding, LSTM
from torch.autograd import Variable
from torch.nn.utils.rnn import pack_padded_sequence, pad_packed_sequence
## We want to run LSTM on a batch of 3 character sequences ['long_str', 'tiny', 'medium']
#
# Step 1: Construct Vocabulary
# Step 2: Load indexed data (list of instances, where each instance is list of character indices)

arunreddy / clean_audio.sh
Created October 22, 2017 20:35 — forked from devoncrouse/clean_audio.sh
Using Sox (http://sox.sourceforge.net) to remove background noise and/or silence from audio files (individually, or in batch).
# Create background noise profile from mp3
/usr/bin/sox noise.mp3 -n noiseprof noise.prof
# Remove noise from mp3 using profile
/usr/bin/sox input.mp3 output.mp3 noisered noise.prof 0.21
# Remove silence from mp3
/usr/bin/sox input.mp3 output.mp3 silence -l 1 0.3 5% -1 2.0 5%
# Remove noise and silence in a single command

arunreddy / arch-linux-install
Created December 5, 2015 04:06 — forked from mattiaslundberg/arch-linux-install
Minimal instructions for installing arch linux on an UEFI system with full system encryption using dm-crypt and luks
# Install ARCH Linux with encrypted file-system and UEFI
# The official installation guide (https://wiki.archlinux.org/index.php/Installation_Guide) contains a more verbose description.
# Download the archiso image from https://www.archlinux.org/
# Copy to a usb-drive
dd if=archlinux.img of=/dev/sdX bs=16M && sync # on linux
# Boot from the usb. If the usb fails to boot, make sure that secure boot is disabled in the BIOS configuration.
# Set swedish keymap
