References Introduction This section gives a brief overview of random forests and some comments about the features of the method. Overview We assume that the user knows about the construction of single classification trees. Random Forests grows many classification trees. To classify a new object from an input vector, put the input vector down each of the trees in the forest.

Big channels prefer trading with big channels. At the same time, the offering of paid promotion is increasing, making it easy for artists to resort to paying for their reposts. As the importance of SoundCloud expands beyond electronic music, labels of all sizes are catching on to the importance of having their SoundCloud plays on point.

Their marketing efforts are now also directed to SoundCloud, including repost trading and sometimes paid campaigns. While the research methodology of this article was initially intended to address just paid repost marketing, the findings apply to Analysis paper on outliers in general.

We were shocked by the results, even as they affirmed the belief that we had already formed by intuition — that the value of reposts was being diluted. It turns out that followers are not the best indicator for how many plays you can expect to get from a repost. The value of a repost is directly linked to the nature and behavior of the reposting SoundCloud channel.

How often they upload, repost and who their audience comprises of are all impacting factors.

As the SoundCloud trading atmosphere is like the Wild West, these findings can help you better choose your repost partners, as well as better estimate the value of a paid promotional offer. Methodology For this research, we paired up with someone with experience in statistics and coding, as we needed to mine data from the SoundCloud API.

By day Tim works for a notable management consulting firm, where he crunches data to find where businesses can Analysis paper on outliers efficiency and save money. Tim took it upon himself to analyze the data and to estimate the real efficiency of paid SoundCloud promotion. The research question that Tim set out to answer is one that many SoundClouders may have asked themselves at some point: The answer to this question would also have implications for traditional non-paid reposts, as the mechanics are identical in nature.

To answer this question, we had to pull a huge amount of data on individual tracks. Not just total plays and hearts, but detailed information such as plays gained from reposts, who reposted what tracks, and how many followers those channels had. This is what applications and websites such as Hype Machine and Artist Union use to access upload information and incorporate embeds from.

Tim wrote a script that crunched the numbers on 8. To avoid outliers messing up the data, such as a 1 Hype Machine charting position or a track with several strong YouTube uploads that would draw traffic back to the SoundCloud uploadwe picked tracks with minimal outside exposure.

We limited the age to less than two months old, as we assumed that after that period, the track would be at the end of its promotional cycle and any additional plays would be unlikely to result from active repost promotion.

How we established the contribution of a repost by a specific SoundCloud channel to an upload, is best explained as follows. Then, channels X and Y repost another track, leading to plays and another track reposted by channels X and Z earned plays.

The findings are shocking.

In other words, if a You, like us, had likely expected this number to be much higher. Most of the low-ratio accounts were the repost channels, who reposted frequently throughout the day and had few original uploads on their account.

By contrast, the high-ratio accounts were the labels and artists, who reposted significantly less and uploaded more often. These varying play-to-follower ratios support our initial fear; that the value of reposts is diminishing.

A repost by a highly engaged The difference is significant, and reinforces the notion that you need to be careful in who you team up with. The secret behiind strong reposts So why do labels and artists have higher engagement ratios?

Labels and artists tend to curate more when it comes to reposts and uploads, favouring quality over quantity, allowing them to develop dedicated superfans. The opposite is true of promotional channels, who prioritize quantity over quality in a pursuit for more followers and scaling their networks.

The trend on SoundCloud, particularly with promotional channels, is to pair consistent reposts with like-to-download gate inclusion in order to accelerate follower growth. A channel might incorporate another channel in the download gate of their track, which then gives them an incentive to consistently repost that upload.

That other channel might then do the same, and receive consistent uploads as well. The result is a perpetuating cycle, where the increase in followers leads to more exposure but not per se more plays.

Also it creates an overlap of followers, which is common with SoundCloud networks that grow through daily repost and mutual gate-inclusion. Eventually they end up ignoring the channels, or unfollowing them. The outliers are the ones that repost less frequently and upload more, acting more like labels.

The highest ratios are found with artist channels, who not only repost less often and upload more than promotional channels, but also exhume a personality that fans can connect with. The more a channel reposted per day, the less engaged their audience.Contents.
