Koneoppiminen ja Googlen algoritmi

Published by Joni on March 29, 2017

Johdanto Tämä postaus sisältää muutamia Rand Fiskinin (MOZ) “What Deep Learning and Machine Learning Mean For the Future of SEO” -videosta syntyneitä ajatuksia. Video löytyy täältä, ja se kannattaa katsoa jotta pysyy kärryillä. Mikä on SEO:n tulevaisuus koneoppimisen myötä? Kukaan ei varmasti tiedä, miltä osin Google on jo implementoinut koneoppimisen periaatteita sijoittelualgoritmiinsa.

Kohtaamisongelmia opiskelija-startupeissa

Published by Joni on March 29, 2017

Johdanto Tapasimme Timo Herttuan kanssa Helsingissä elokuussa 2014, ja startup-harrastajina keskustelimme tietysti startupeista. Tämä artikkeli tiivistää tuon keskustelun tulokset. Lähdimme liikkeelle siitä, että opiskelijavetoiset startit ohjattaisiin löytämään ja ratkaisemaan suuryritysten (Kone, Wärtsilä, jne.) ongelmia. Tällä vältettäisiin “triviaalien applikaatioiden ongelma”, jossa keskitytään asioihin, joilla on marginaalisen pieni vaikutus ihmisten elämään merkittävien ongelmien sijaan. Haluamme tässä yhteydessä korostaa, että kaikki startup-toiminta on tottakai haluttavaa ja…

Published by Joni on March 29, 2017

Introduction By definition, a dilemma is a trade-off situation in which there are two choices, each leading to a negative outcome.

Organic reach and the choice of social media platform

Published by Joni on March 29, 2017

(This is work in progress.) Introduction It is a well-established fact that the organic reach in a dominant platform decreases over time, as the competition over users’ attention increases. There is thus an inverse relation: The more competition (by users and firms) in a user’s news feed, the less organic visibility for a firm. The problem How would a firm willing to…

About moral hazard and banking crises

Published by Joni on March 29, 2017

Introduction The struggle against moral hazard in banking is constant and real. There’s no turn-key solution for eliminating it, but it must be kept in mind at all times by policy makers. Consider the following citation from Wikipedia: “The role of the lender of last resort, and the existence of deposit insurance, both create moral hazard, since they reduce banks’…

Big data is not enough data

Published by Joni on March 29, 2017

There is a big data fallacy My argument here is simple – even though it’s a common argument that “everything is tracked”, marketers face a big data fallacy when assessing their ability to predict consumer behavior. The reason is explicated here [1]: “On any given occasion, everything from personal factors such as how well a person has slept the night before,…

How to measure offline marketing with online metrics?

Published by Joni on March 29, 2017

Introduction The issue with offline marketing is tracking. For many offline marketing efforts, such as exhibitions and networking events, it’s hard to track results. Participation in these events is often expensive, and the results are evaluated on a qualitative basis. Although qualitative evaluation is better than nothing, quantitative data is obviously better. And in many cases, we can do that –…

Using the VRIN model to evaluate web platforms

Published by Joni on March 29, 2017

Introduction In this article, I discuss how the classic VRIN model can be used to evaluate modern web platforms. What is the VRIN model? It’s one of the most cited models of the resource-based view of the firm. Essentially, it describes how a firm can achieve sustainable competitive advantage through resources that fulfill certain criteria. These criteria for resources that provide…
